    It brings up a lot of

    questions.

    There have been studies in the past demonstrating activation of the VNO when exposed to none. Does

    that indicate the VNO/VND is only one of several potential pathways for detection of none?

    Since none is

    detected through senses other than the VNO/VND, how does the specific pathway effect the sexual excitation response

    within the brain? Is there a difference? If so, what is it?

    I only remember seeing evidence

    for A1 dectection by the VNO, but I cold be wrong.

    Perhaps the next obvious question is one addressing the

    possibility of pheromonal pathways from the regular olfactory system.

    My guess would be possibly, but another

    possibility is some sort of conditioning.

    Also, does -none have the same

    effects on people who can't smell -none?

    Bruce has said it does. I haven't seen

    any studies indicating VNO activities with none either.

    My understand was that it is all olfactory, which

    makes it kind of ironic that you don't have to smell it to be affected.

    Nice post! Interesting.



    The problem with such studies is that they are designed by people with no experience in perfuming, aromatherapy,

    or wearing pheromones.

    So they choose to expose subjects, for example, to ether alcohols and extreme, bizarre

    smells like that instead of smells with real world relevance, just because detection threshholds are easy to measure

    or some such reason.

    Then they make conclusions about olfaction in general. Duh.

    So such studies

    lack the subtlety both to address questions precisely and also to detect phenomena of interest.



    So, for example, the study's measurement methods are probably blind to various interactions between

    pheromone activity and smell perception, and to the most important ones, if so.

    But it does suggest again that

    -none doesn't trigger the VNO, and therefore works through standard olfaction. We knew that from Erox.

    But the

    sensitivity/-none perception interaction testing was flawed for the reasons I mentioned.

    There needs to be a

    distinguishing line between olfactory in terms of SMELLING something and being affected by it via the VNO. That is,

    just because you can't smell it, doesn't mean its not having effect on the VNO. The study cited at a quick glance

    demostrates that a small yet statistically correlation existed between those with better olfactory function and

    detection of none. "Results suggest that the human VND does not play a major role in sensitivity toward odorants or

    the perception of androstenone". Thats fine, no one ever said you would consciously smell it....

    good point, the study doesn't

    address whether or not the effects of -none are still occuring with a covered VNO. After all, we can smell A1 and

    that also has an effect on the VNO, so why can't -none?

    Findings from several different

    mammalian species show that the VNO is not required for a response. Findings from many different mammalian species

    show that the typical mammalian response to pheromones of the opposite sex is an increase in luteinizing hormone

    (LH), which alters the LH/follicle stimulating hormone(FSH) ratio, which alters sex steroid hormone production,

    which alters behavior. Since there are now human studies that show either an LH response or testosterone response to

    pheromones from the opposite sex, the case for the functionality of the human VNO is becomming a mute point. Of

    interest to some may be that homosexual rams do not show the typical LH response to estrus ewes. You'll be reading

    more about this someday soon.

    What I would like to see is

    the extent to which LH, FSH, and hence testosterone response is affected from exposure to opposite sex pheromones.

    There is a wide array of applications for something that can be stimulatory enough to cause significant and

    consistant results.

    Default Copulins/VNO's Role in Olfaction/Classifying Types of Olfaction

    I want to address briefly three issues which were raised above: using copulins in

    men's products, the VNO's role in olfaction; and classifying types of olfaction. None of these issues are new,

    though they are often reintroduced on the forum in one form or the other; and so it would be nice to get everybody

    on the same page a little bit, for that reason. I probably should have broke this into three posts, but "oh, well"

    (guess I won't be getting as many "points").

    * Copulins have other effects besides raising testosterone

    for the user, so it's not a "clean" thing, and not simple to apply. I thought long and hard before adding a trace

    amount of Jutte-like copulins to my L-S product, Pheros, which is a man's scent ("Not enough to suggest

    femininity" was a goal there, and I looked at all available anecdotal reports in the forum before determining

    amounts, which I'd be happy to share.). I think it makes the scent good for orgies, as Koolking and Sue use it, and

    also supports virility to some small extent, as has also been reported anecdotally on the forum. That is not to say

    there might not be a tradeoff of some kind. Available data suggests it's not always a good idea to add cops

    indiscriminately to a men's product. We really explored the issues thoroughly on the forum back in those days

    following the release of EW.

    * Obviously, we've known for a while that the VNO is not required for

    phero-responsiveness. That is not to say the VNO is boring, or a "mute' issue. The process may be very different

    for the VNO path (e.g., well-defined patterns of brain activity) versus standard olfaction (e.g., LH/steroidal

    changes have been identified here), which is more indirect and serpentine by comparison. The role of the VNO is

    crucial to learn for constructing bigger pictures, such as the one I sketched in my A1 "analysis" post a couple days

    ago. Phero-responsiveness is only partly a matter of LH and testosterone changes, for example. A1 lights up the

    social cognition and attention areas of the brain when female subjects are in the presence of males. That is a much

    bigger picture than the hormonal change picture; and more fundamental. The VNO works through direct perception by

    brain cells, bypassing all that other stuff, as far as we know presently. It is time to enlarge our thinking and

    integrate some things.

    *For our purposes, I think about olfaction like this:

    Types of Olfaction Relevant

    to the Study of Pheromones


    A. Conscious olfaction

    1. Pheromonal conscious

    a) VN pheromonal

    olfaction
    b) Non VN pheromonal

    2. Non-pheromonal conscious

    B. Unconscious olfaction (I'm not

    implying that there's a clean break here between conscious and unconscious in the real world, BTW.)

    1.

    Unconscious pheromonal olfaction

    a) VN pheromonal olfaction
    b) Non VN pheromonal

    2. Unconscious,

    non-pheromonal

    This means it makes sense to identify at least 6 kinds of olfaction for our

    purposes
    , as just listed. These are the main types that have been discussed already in the forum, after all.

    Given this, it should be easy to understand why there has been so much miscommunication about "olfaction", even

    among serious researchers. As a partial solution, I am proposing that we all use the classification I just provided,

    to make sure we are clear with each other, and avoid useless semantic debate. There are of course, other variables

    we could use, such as aesthetic versus biologically functional olfaction, (-- which would here also

    involve a very, very fuzzy line in the real world; but I think it can be a useful logical distinction, at

    least.).

    Nice categorization, doc.



    It was my understanding that A. 1. a) is the null set. I will state, not as proof of the previous sentence, but

    merely as comment, that we currently have no language to describe A. 1. a). Your categorization begins the process

    of creating such a language.

    If A. 1. a) is truly a null set but added for the sake of completeness, we should

    lay all our assumptions on the table and create
    A. 2. a) VN nonpheromonal olfaction

    and

    A. 2. b) Non VN

    nonpheromonal olfaction

    Why prejudge the function of the VN? It may sense chemicals other than pheromones. Or, if

    we choose to define the VN as the pheromone-sensing organ, then we may choose to broaden considerably our definition

    of what pheromones are.

    Given my claims above, we would also add B. 2. a) and B. 2. b) to allow for the

    possibility of unconscious detection by the VN of nonpheromonal signals.

    Examples:

    A1a: null set

    (hypothesis)
    A1b: 'none smells like cat piss
    A2a: null set (hypothesis)
    A2b: the smell of baking bread
    B1a:

    paradigmatic VN detection
    B1b: unconscious smell of cat piss in 'none(someone who's been around it for hours and

    is no longer is consciously aware of it)
    B2a: nonparadigmatic possibility of VN detecting nonpheromones
    B2b:

    unconscious smell of baking bread (someone who's been around it for hours and no longer is consciously aware of

    it)

    Nice post, nonscents! I agree

    with your logic. The VNO might well be involved in biologically functional olfaction other than that of one

    animal communicating to another (e.g., environmental smells indicating dangers or the presence of water). The

    examples you gave are good ones. I guess I should have put the biologically functional/purely aesthetic category in

    there, too (at least under conscious, though I guess it's theoretically possible for a smell to be detected

    unconsciously just for the purpose of, say, making interesting dreams); since you've already brought up test

    cases. Who says being obsessive/compulsive isn't good for anything?

    Lightbulb The "Rod of Olfaction"

    Is the VNO the "Rod of Olfaction?"
    Exaltation, "Preconscious"

    Olfaction, Visual Perception, and the Human
    VNO


    Since at least one person,

    nonscents, is interested in my classification scheme, I'm encouraged to continue the theoretical discussion,

    making the picture even more complicated, in light of nonscents' comments. But hopefully the big picture

    will get a bit simpler and clearer! Uh oh, here comes another long DoctorofScenTology post! Just look at it as a

    free Psychology of Scent lecture, where you won't even get thrown out of the hall for drinking!



    Hey, wait, this is cool! Oh well, at least the hard core alcoholic nerds are still here! Cheers!



    Before anyone assumes things -- no, the "rod of olfaction" has nothing to do with Cyrano de Bergerac or

    Pinocchio! But please do read on, nose drama fans! The title suggests that a motley crew of concepts are about to

    be pulled together under a larger picture of olfaction; and so they will be.

    Regarding nonscents' null set

    thing, have you ever had the sense, when "smelling pheromones", that you "smell something but you don't"? I have it

    often. I bet many of you have had this happen, too. Often, when smelling pheromones, I know I "smell"

    something, but it seems indescribable, or "ghost-like".

    It does seem to "piggyback" onto other smells I

    can "consciously" detect. In other words, it noticeably changes something about the smells I am perceiving.

    In perfuming this is called "exaltation," With exaltation, a smell "glorifies" another smell without being

    itself smellable. A smell that exalts another is a "selfless team player", making the smells it is combined with

    more beautiful, without calling attention to itself. This is, not suprisingly, a primary attribute of musks, and is

    doubtless also a primary attribute of human pheromones, which are components of human musk.

    Why do you

    think folks get increased compliments on their colognes when wearing pheromones? The reason is exaltation.

    If

    you focus on the pheromone smell itself, it seems like it's "not really there". But in another sense, it

    is there, but just very hard to describe, and ghostlike (like a sight having an outline or shadow but

    otherwise lacking qualities one can talk about).

    The airborne pherochemical comes to "mean" something to

    us -- that it, it is perceived -- and even moreso in conjunction with standard, conscious smells we are fully

    aware of; as a smell modifier or "exaltant". But the pherochemical does not seem to be "consciously" smelled in the

    way we customarily think of it, unless in it is presented in unnaturally high concentrations. But if pheromones seem

    not to be "consciously" smellable, this might be the concept's "fault" more than the smell's.



    Something like the process behind "ghost smells" might be a way in which we can smell airborne chemicals

    consciously with the VNO.


    Yes, you heard me right! I said smelling consciously with the

    VNO! It's heresy!

    But first, can we really get away with calling the smelling that happens in

    the case of exaltation "conscious olfaction"? Maybe we can! On the other hand, maybe we should call it

    "preconscious" olfaction instead -- to borrow a term from psychoanalysis -- to distinguish it from both

    "unconscious" and "conscious" olfaction. For psychoanalysts, "preconscious" means potentially conscious:

    presently accessible by consciousness; but not presently grasped by our conscious minds. One way of

    thinking about this is to say that whatever we choose to focus on becomes fully conscious, compared to

    other things in our field of perception that we are not presently focusing on, which are preconscious. If we have to

    have a term for it, this might be the best one.

    Honestly, though, it would probably be more precise to just

    enlarge our notion of what it means to have "conscious smells:" to include things that are more off in the

    background and not so rich for us, and fill in the "null set" talked about by nonscents!

    Since we don't have

    too many words for olfaction, as nonscents noted, we can borrow some concepts from the study of vision, which has

    given us words out the wazoo! (wish I had a smiley for this one!! )

    In particular, the nature of "cone" and

    "rod" vision might throw some "light" on our situation. Those of you who studied the eye in physiology will know

    what I am talking about, but I'll summarize the eye information for those of you who haven't seen it.

    Smelling

    pheromones is partly similar to seeing a faint star in the sky better when not looking directly at it.

    Most of us have had this experience. If not, try it! It's easy to notice! If you kinda look out of the side of your

    eyes on a clear night, you'll see more stars! In vision, this phenomenon results from the difference between "cone"

    and "rod" vision, relative to the structure of the eye. Cones detect color well, and shades of light/dark poorly,

    while rods detect light and dark very well, but are color blind.

    The human eye is structured so as to have many

    cones, but few rods at the part of the eye in the middle of the back; which is struck by light when we

    consciously focus on something we see. Things in the middle of our field of vision are literally more colorful,

    then, due to cones! Slightly further out is a subtle halo of less colorful brightness, due to the greater number of

    rods away from the middle of the back of our eye. Pay close attention to what all you can see right now, and

    you'll get it. Painters from the school of realism, take note!

    So cone vision is more directly connected to

    focal consciousness (the part corresponding to the "figure" as opposed to the "ground", as

    Gestalt psychologists say) than rod vision. Rod vision is better at night, contributing to survival capabilities or

    biological functioning; but is unable to detect richer, more aesthetic aspects of sights, i.e., color.

    Still, rods help keep us safe from background threats to our survival.

    Um, my point being?!



    I am suggesting here that perhaps standard olfactory detectors might similarly be more connected with focal

    (figural) olfaction, whereas the VNO is more connected with the background for other smells we focus on; and

    less connected with focal olfaction.

    The VNO may well be the "rod of olfaction"!



    "Biologist types" invariably assume that the VNO works entirely beneath consciousness. Why? Is it because they

    assume animals behave entirely according to instinct? It's not clear that even this taken-for-granted assumption is

    necessary. Indeed, maybe it's premature to conclude that the VNO is not an instrument of conscious

    perception! After all, rods can be used in conscious vision, but just don't yield as rich of information. Do

    you see the distinction I am trying to make, between something that is unconscious, and something that is

    preconscious; or conscious, but in the background with pared down qualities?

    The similarity between

    rods and VNO receptors seems uncanny. Though my theory about their similar functioning has not been confirmed by

    research, we've not had a chance to know all this until now, due to the exclusive focus on non-human biology

    when it comes to VNOs! Biologist types have been doing all the talking! But rats, pigs, and fruit flies aren't so

    kind as to share their experiences directly with us. People can! So it is time for regular people, and

    psychologists, to speak up. IMO, that is what makes this forum better than typical scientific conferences and

    research papers on pheromones in so many respects.

    Just as there are two different kinds of cells that

    detect light, for color and light; there appear to be at least two different kinds of cells that detect airborne

    chemicals.

    As with the case of biologically functional rod vision, the VNO contributes to survival by

    helping us "smell" things we normally couldn't, for the the sake of biological fitness. But the "smells" in

    question are barren of describable aesthetic qualities that conscious smells normally possess.

    Why?

    Quite a few molecules are required for the smell areas of the brain to flesh out a smell's multifarious qualities.

    But the VNO specializes in faint signals, where just a few molecules of an airborne chemical are enough to trigger

    the biologically desired reaction. This is like having good night vision to a nose. VN olfaction doesn't seem to

    process jumbles of complex information nearly as well as standard olfaction, however. The VN system seems more

    easily overwhelmed.

    In vision the multifarious qualities that make something we see appear rich are called

    "colors", of course. In olfaction we have no word for it -- which should tell us how out of touch we humans have

    become with our noses!
    Perhaps because we aren't as intimate with our senses of smell these days as we

    could be, we typically don't recognize all our smell experiences as smells at all!

    That doesn't mean we

    couldn't learn to recognize them, as the CptKipling's article suggests. But I am talking about conscious

    recognition through the VNO, not through "standard" olfaction, like I said. The problem with this idea,

    theoretically speaking, is that I've had the "ghost smell experience" with -none, -rone, and -nol; as well as the

    known VNO activator, A1. But the former three -mones are not thought to activate the VNO. Hmmmmm...

    Maybe this

    suggests that there might even be a third type of smell receptor, or at least that we don't yet understand standard

    and VNO olfaction too well. Or both. Or, more parsimoniously: Maybe these other pherochemicals are

    converting to something on our skin that is detected by the VNO!? We already know -none can be converted to

    A1, and that -nol can go back to -dienol. Perhaps that's part of the answer.

    But for now, this phenomenon must

    remain a mystery of smell, "in some sense" (pun intended). But never say "alas" if you have a lass.

    presently grasped by our conscious minds. One way of thinking about this is to say that whatever we choose to

    focus on becomes fully conscious, compared to other things in our field of perception that we are not

    presently focusing on, which are preconscious.

    Honestly, though, it would probably be technically best,

    eventually, to just enlarge our notion of what it means to have "conscious smells" to include things that are more

    off in the background and not so rich for us, and fill in the "null set" talked about by nonscents! But for now,

    enough of us remain out of touch with our worlds and ourselves in this way to call it something "lesser" than

    conscious.

    Since we don't have too many words for olfaction, as nonscents noted, let's borrow some

    concepts from the study of vision, which has given us words out the wazoo! (wish I had a smiley for this one!! )



    The "cone/rod parallel" from the science of visual sensation and perception might throw some "light" on the

    situation. Those of you who studied the eye in physiology will know what I am talking about.

    Smelling

    pheromones is partly similar to seeing a faint star in the sky better when not looking directly at it.

    Most of us have had this experience. If not, try it! It's easy to notice! If you kinda look out of the side of your

    eyes on a clear night, you'll see more stars!

    In vision, this phenomenon results from the difference

    between "cone" and "rod" vision, relative to the structure of the eye. Cones detect color well, and shades of

    light/dark poorly, while rods detect light and dark very well, but are color blind.

    The human eye is

    structured so as to have many cones but few rods at the part of the eye in the middle of the back

    which is struck by light when we consciously focus on something we see. Things in the middle of our field of vision

    are literally more colorful, due to cones, then! Slightly further out is a subtle halo of less colorful brightness,

    due to the greater number of rods away from the middle of the back of our eye. Painters from the school of realism,

    take note!

    So cone vision is more directly connected to focal consciousness (the part corresponding

    to the "figure" as opposed to the "ground", as Gestalt psychologists of perception say) than rod

    vision. Rod vision is better at night, contributing to survival capabilities or biological functioning; but

    is unable to detect richer, more aesthetic aspects of sights, i.e., color. Still, rods help keep us safe from

    background threats to our survival.

    My point being?!

    I am suggesting here that perhaps

    standard olfactory detectors might similarly be more connected with focal (figural) olfaction, whereas the

    VNO is more connected with the background for other smells we focus on; and less connected with focal

    olfaction.

    The VNO may well be the "rod of olfaction"!

    Maybe it's premature to

    conclude that the VNO is not an instrument of conscious perception! After all, rods can be used in conscious

    vision, but just don't yield as rich of information. Do you see the distinction?

    We have

    not had a chance to know all this until now, due to the exclusive focus on non-human biology when it comes to VNOs!

    Biologist types have been doing all the talking! But rats, pigs, and fruit flies aren't so kind as to share their

    experiences directly with us. People can! So now it is time for regular people, and psychologists, to speak up.

    That is what makes this forum better than scientific conferences on pheromones in so many respects.



    Just as there are two different kinds of cells that detect light, for color and light; there appear to be at

    least two different kinds of cells that detect airborne chemicals.

    Similarly, the VNO contributes to

    survival by helping us "smell" things we normally couldn't, for the the sake of biological fitness. But the

    "smells" in question are barren of describable qualities that conscious smells normally possess. In vision these

    qualities are called "colors", of course. In olfaction we have no word for it -- which should tell us how out of

    touch humans have become with their noses!

    Perhaps because we aren't in touch with our senses of

    smell these days as we could be, we typically don't recognize the experiences as smells at all. That doesn't mean

    we couldn't learn to recognize them as such.

    The problem with this, theoretically speaking, is that I've

    had the experience with -none -rone and -nol, as well as the known VNO activator, A1; but the former three -mones

    are not thought to activate the VNO. This suggests that there might even be a third type of smell receptor, or at

    least that we don't understand standard and VNO olfaction too well yet.

    So for now, this phenomenon must

    remain partly a mystery of smell.


    Great post, DST

    Hey Doc. How serendipitous! I

    was just driving to work from the gym an hour ago and the VN-consciousness discussion was percolating

    mentally.

    As I recklessly passed a car, it dawned on me suddenly, to make this discussion more vivid I need a

    model. Yes, I've got it! I will make an analogy between olfaction and vision.

    I get to my desk; turn on my

    computer . . . and . . . read your post. Well, I guess it was inevitable.

    I have not had the experience

    of exaltation as you describe it. Therefore my categorization is much more rigid than yours allowing no examples of

    conscious VN sensing.

    Let me state outright that I am not emotionally invested in what I am saying here. My goal

    is to tease out the intellectual implications of the little we know. I would like to have the various positions

    formulated clearly so that we can, as clearly as possible, confirm and falsify them. If my position is falsified I

    will be happy because my knowledge has been increased and my ignorance diminished.

    Part of the sociology of

    science is that the objective truth is that over which there is intersubjective agreement. There is a lot of

    intersubjective disagreement over ethical and moral issues so we say that these issues do not fall under the rubric

    of science. "The thermometer reads 50 degrees Celsius" is a claim over which there can be intersubjective agreement

    and can be useful in scientific inquiry.

    I would argue the VN olfaction is analogous to visual perception of

    auras. Some people claim to have a kind of "second sight" in which they perceive other people's auras. These

    aura-seeers recognize that the auras are not visually perceived in the same manner as normal objects are visually

    perceived.

    I do not perceive auras. It is my understanding that most people do not perceive auras. The goal of

    those who wish to obtain the imprimatur of science for auras is to find some means to make auras intersubjectively

    accessible (Kirilian photography?).

    In my categorization VN olfaction is like aura perception. And that is

    precisely the big attracton of pheromones for so many here. Many are attracted by the fact that they can influence

    other people in a way that is other than conscious. Many people enjoy the possibility that pheromones give them a

    secret (read: "other than conscious") power to influence others.

    Pheromones are of such interest for the same

    reason that NLP and hypnosis are: they hold out the possibility that we can change the behavior of other people

    without them consciously understanding why.

    If I were strongly wedded to the view that VN sensing must be

    nonconscious I would explain DrST's experiences as follows:

    1. First he smells sandalwood essential oil and is

    conscious only of normal olfaction.
    2. Then he smells sandalwood essential oil to which a pheromone has been added.

    Now he is conscious through normal olfaction of sandalwood and he is conscious of something like: increased (or

    descreased) sweating, increased (or decreased) heart rate, increased (or decreased) muscle tension, change in mood,

    etc.

    So, in scenario 2, where we are positing the activation of the VNO, there is a consciousness of a

    difference. But the consciousness is not of a (meaningful) olfactory difference. Rather, there is an association

    between the sandalwood-pheromone mixture on the one hand, and the physiological changes on the other.

    If I were

    strongly wedded to DrST's position I would argue against my own position as follows:

    Look, nonscents, I know

    you personally, and you have always been ideologically opposed to radical behaviorism which eliminates consciousness

    from psychological explanations. Well, in this case you have fallen prey to what is essentially a behaviorist

    conspiracy. The fact is that much of what we know of pheromones comes from animal research and the human research

    comes out of laboratories with a strong behaviorist bias. So the research looks at stimulus-response correlations

    where the stimuli are atmospheric exposure to pheromones and the responses are measurable physiological reactions.

    There really is not sufficient evidence to prejudge VN sensing as preconscious.


    OK, crises are

    exploding all around me. That's enough speculation for now.

    Thanks for your continued provocation and refining

    of my thinking, DrST.
    The more you sweat in peace, the less you bleed in war.

    I agree -- very

    serendipitious!

    Well nonscents, it's a pleasure to read your posts, which show a grasp of some concepts of human

    science. It's obvious you have some background in it!

    (I did notice, however, that you used the word

    "preconscious", when I think you meant to say "unconscious" or "non-conscious.")

    It's interesting that many who

    "teach aura perception" instruct you not to look directly at the place you expect to see the aura. Perhaps rod

    vision is somehow involved in the experience?

    The experience of exaltation is intersubjectively verifiable, in

    the case of musks, with experience. You learn to smell exaltation through working with smells and perfumes, but

    anyone can smell the effect. Due to this intersubjectivity of sorts, it's really not questioned in the traditions

    of perfumery. Part of the huge depth and mystery people experience when smelling a musk might be due as well to the

    smell being larger than stereotypical, standard olfaction can process. The multifaceted smell presumably evokes a

    reaction in which we bring more of our sense of smell vividly into play than we typically do in mundane life.

    Regarding individual pheromones, the raw individual chemicals which combine together (with other smells) to make a

    musk smell, it might be a little more difficult to intersubjectively verify. But still, I think it's

    recognizable as the same or similar phenomenon, and as such, intersubjectively verifiable. It wouldn't be

    that hard to test, although it would be challenging (but not hopeless) to isolate and elimenate the associative

    effects you propose as possible confounds. ("Confounds" are secondary, nontheoretical causes of an observed effect

    that can screw up your ability to interpret data in the way you'd like to.).

    Interesting you both pick vision

    analogies, considering we may have lost VNO processing to tri-color vision processing.

    I can't say I agree with

    DST's vision analogy of rods and cones to VNO and main olfactory. I much prefer the comparison to aura reading.

    Everybody can consciously see with thier rods, with the exception of Vitamin A deficient people. No training is

    required for this. Most people cannot see aura's without lots of practice and training. I would guess most people

    couldn't see them even with training, but we can't know since very few people try.

    Enough of my useless

    opinions. My real reason for posting is to give my opinion on the richness of smells. With color vision, we have 3

    different pigments in cones. One type in rods. This is why we don't see colors in dim light when our rods are

    most active. All the colors we do see are from the different sensitivities of our cones to different photon

    energies (colors) This means the whole range of colors we see is from our brain processing only 3 color signals.



    With smells, using the lock-and-key model, we have thousands of kinds of receptors. Smells are even richer than

    colors, just without any resolution. Its more difficult to track down the source of a smell than it is to track the

    source of a photon.
    We don't consciously percieve which receptors are being activated by a smell. When we smell a

    lemon, there are numerous kinds of receptors activated, we don't recognize each individual one, we recognize the

    combination as lemon. Similarly, if we see an orange light, we don't think that its "red" at a certain intensity

    and "green" at a lower intensity, we recognize the combination as "orange".

    Just about every smell we can

    identify is a "color" of smell. Usually we identify them by one certain source that produces a smell of that

    "color" For example, smells like roses, or strawberries. There are enough different kinds of receptors to produce

    different combinations that almost everything has its own "color", while with light there are so few combinations

    that many things have the same color.


    Uh-oh, DST is viewing this thread as I'm typing. He's probably got

    something posted before I get this one finished. Hopefully he doesn't say anything that'll make mine look

    stupid.....

    Just a quick note that is far

    from ground braking:

    The lock and key theory for olfactory chemo-sensing has been questioned a few times. From a

    lay-man's logic point of view, it seems highly implausible that there would be thousands of receptors coded to

    detect every single chemical we can smell. The Molecular Vibration theory works on the basis that there is some way

    for the nose to differentiate between the differences in vibrations between different chemicals.

    Thanks for the additional info

    on rods and cones, Einstein. I agree that smells are more complex than colors.

    My theory is certainly just

    speculation to be explored at this point. I'm trying to flesh out the function of the human VNO based on actual

    olfactory and usage experiences with purported pheromones, since this type of experiential data has not yet been

    mined or added to the mix. Only we can do this at present.

    BTW, I'm not sure I understand the aura reading

    analogy. What is aura reading being compared to, exactly?

    Thanks for the note Kip. I agree the lock and key

    thing is too cumbersome and simplistically mechanistic. There is almost no way it can be sound as it is. It smells

    fishy! That is not to say it is time to completely forget it. The vibrational theory still needs more development

    and data to support it.

    What is the vibrational theory?

    Do you have any good references? It sounds interesting, and definitely appeals to the physicist in me.

    The theorist is

    biophysicist, Luca Turin!

    Though a biography, this is the most popular reference, and the book you

    probably want to start with, The Emperor of Scent, by Chandler Burr:

    I reviewed the book for Human Nature

    Reviews

    http://human-nature.com/nibbs/03/burr.html

    Luca contacted me to let me know that he

    had published in "Nature" early in his career, so some of my comments must be taken back. However, his theory was

    pretty much discredited by presenters at the last Association for Chemoreception Sciences conference--and their

    findings should soon be published in a peer-reviewed journal. It's always great to learn about other

    theories/models, but I think it's also prudent to take what already is known and use extend the mammalian model of

    olfaction to humans and to human behavior. For example, the VNO debate has not been fruitfull--still no evidence of

    a connection to neuroendocrine function, and social environmental sensory input (e.g., olfaction) must alter

    neuroendocrine function to alter behavior. That makes VNO research less likely to provide more than questions about

    why we still have some sort of VNO. In contrast, putative human pheromones have been shown to alter levels of

    luteinizing hormone--just as pheromones do in other mammals (and this is a direct link from the social environment

    via gene activation to neuroendocrine function).
    Those who are interested in reading more about this can check

    out my technical papers or my book--there are a lot more facts than speculation--and the facts are all

    referenced.

    I'm glad the review didn't

    simply trash Turin, like many would have.

    I agree that both approaches are important. Science could never go

    anywhere new without theory and speculation. All good research is theory driven. One can only get so far summarizing

    the known facts and using deductive reasoning from there. On the other hand folks here seem continually hungry for

    new research studies.

    I'm all for knowing mammalian pheromone research. Bring on the studies. We need more

    posts of recent studies. Sometimes the habitual reliance on non-human research to explain humans can go too far,

    however. For example, why would one think every human behavior is, and must be, caused by an endocrine change? Is it

    really necessary to claim all of psychology can be reduced to hormones? Is it even remotely possible? How about one

    example of a complex everyday human behavior that is caused only by hormones? That's a pretty radical and

    unnecessarily contentious claim, unless I am missing something. How can we be sure that isn't reductionistic and

    simplistic? What is the neurological evidence for this? Is there a particular reason to ignore 100 years of

    psychology psychiatry and neurology research, and limit ourselves to extrapolating from non-human mammalian

    research? Must the different branches of science ignore each other and be at war? Am I totally misreading the

    statement? I hope so.

    Regading the VNO, I agree the debate is boring! I'm not yet really interested in any VNO

    debate, as there really isn't enough info to debate, especially given Pherin's secrecy. Instead, I'm just curious

    to know more. I don't see any reason to be either optimistic or pessimistic about it. There is really not any

    research that suggests it is not functional either, and Pherin's research is pretty suggestive, from what we know

    of it.

    We here in the forum are practitioners rather than journal/conference publishers. Therefore we are free

    to speculate, and even need to to get where we want to go. There is no conflict here between a lit review of

    facts and educated speculation or theorizing. Both have their place and should be able to build on each other. Many

    here have already read the most prominent papers/books on pheromones, and are wanting to go from there. one of tghe

    biggest needs is new studies that address more interesting (from our point of view here) questions.

    It would be

    interesting to see on what grounds Turin is discredited.

    Any interaction

    between the social environment and biological function MUST be preceded, minimally, by a neuroendocrine change. Some

    of the neuroendocrine changes are not directly measured, but the influence of the neuroendocrine change is often

    very clear when associated with an endocrine change.

    Your reading more into the statement than what I can directly address, but most of your

    questions might well be reduced to a scenario that you propose is not caused only by hormones--a complex behavior,

    or a simple one. One caveat, neurotransmitters are hormones, and hormones--especially the steroid hormones alter

    neuroanatomy. A similar statement "There is no non-olfactory biological basis for visually perceived physical

    attraction" also elicits the questions that you pose. Yet, no one has ever offerred a non-olfactory biological basis

    for visually perceived physical attraction. Instead, I am asked for examples of biologically based complex behavior

    that are not driven by olfaction. My Neuroendocrinology Letters paper addresses all the issues surrounding my

    statements.

    Unfortunately, I will be traveling for the next three weeks, so will not be able to participate

    in the Forum for a while.

    Mr. Kohl, I appreciate your

    post, and hope you and other knowledgeable people with an interest in attraction, olfaction and pheromones will

    continue to participate, and increase participation, in this forum. As Turin demonstrated, there is something to be

    gained in "dialoging with collective practical experience" regarding olfactants such as pheromones, essential oils

    and perfumes; especially as applied to romance, attraction, and other social situations.

    I along with many folks

    here have been familiar with your interesting paper; and also your theory of pheromonal conditioning of visual

    attraction. I honestly don't find the paper to address these particular issues here, however, and am confused about

    some of the quasi-psychological statements you made.

    If you're saying you know why humans do what they

    do, and that the answer is hormones; and you want people to understand your claim, or even potentially

    come to believe it; then you ought to be able to produce an example of hormones causing some everyday

    human behavior. I don't know of any such behavior, personally. The burden of proof, or the burden to suggest

    something better, is not on those who happened to be there when you proclaimed this; because no one else here had

    claimed they know why humans do what they do.

    If you had just said that hormones are an influence on behavior,

    BTW, I would have agreed and moved on. That would be consistent with what we know in psychology.

    Also as regards

    why people do things, what do you mean by "a neuroendocrine change?" For example, are you referring to specifically

    to neuroendocrine cells; to everything having to do with the fields of neurology and endocrinology, or to something

    "in the middle"?

    I'm not sure it's so easy to say, "caveat: neurotransmitters are hormones." Of course, it's

    just semantics in a way, but my understanding is that a neurotransmitter is not merely a kind of hormone, even

    though there have been those who said this in the past. Noted differences between neurotransmitters and hormones

    include site of action, site of production, place of storage, medium of action (bloodstream, etc), distance of

    action, complexity of action; and specificity of action. Some do say there is a large overlap between the two kinds

    of chemicals. There is undoubtedly some overlap. But I've heard it said in this case that there are exceptions in

    both logical directions (Not all N are H, and vice versa.).

    I'm willing to set aside for the moment the

    semantics issues and definitions if you want. But even if we can just agree that every behavior has "biochemical

    messenger" correlates (There are many other biological correlates to every behavior, BTW, and even many other kinds

    of biochemical correlates in particular.); that premise does not imply all behaviors are caused by certain

    specific sets (and amounts) of neurotransmitters or hormones, (or by behaviors' other biological correlates for

    that matter). Correlation does not imply causation, for one thing. This even holds in cases where correlates are

    sequential, and where correlations are exceptionally strong.

    To wonder whether your idea could be sound might

    be fun speculation, however. I'm willing to go there with you for the sake of interesting discussion. We'd have to

    define carefully what it means for some thing to "cause" a behavior, though. Then it might be possible on

    some level
    to identify one "thing" as the cause, since human behavior is so complex.

    So what then of the

    position that thoughts, beliefs and intentions relative to memory, present perceptions, and imagination are the most

    important causes of behavior? Besides accounting for the big picture in psychology, this narrative theory dovetails

    nicely with the whole field of neurology, including such cutting edge areas as plasticity and neural networks.



    Each human action is a unique event. Any successful candidate for any true cause of any behavior must account for

    that behavior's uniqueness. That is one of the main reasons reductionistic explanations of behavior (e.g., hormonal

    mechanism) don't work. That uniqueness can only be found in the psychological life story of person making the act

    in question. A life story is the only possible medium with which we can make sense of an individual, momentary act.

    The story literally defines the act. So non-narrative theories of psychology are failed candidates for

    consideration as potentially successful theories. Other theories fail to pass muster. Even chains of biochemical

    events in brains can only make sense in their narrative context where human actions or experiences are concerned,

    and can therefore only be defined in narrative terms (though in this case the narrative would have biological

    aspects).

    Of course, there is a relevant history to the discussion of why we do what we do. The history of this

    discussion is the history of psychology. However, since you have openly expressed unfamiliarity with,

    disinterest in, and contempt for the whole field -- and not merely some radical take on it -- on a number of

    occasions; I'm confused as to why you raised the subject of human behavior in general (as much as I love to

    discuss that subject). Isn't that trying to do psychology?

    Reductionist principle could

    still work. Create a map of the locations and momentums of every atom in all 12 trillion neurons, 100 trillion

    glial cells, and every other chemical and ion inside the head. Run an extremely complicated computer simulation to

    calculate thier trajectories, of course taking into account heisenberg uncertainty, and you will get an answer of

    what most likely happens next (anytime you invoke quantum physics you can only end up with a probable answer.) The

    past experiences of the individual are taken into account by the current layout of the neurons.
    Its not

    practical, earth will have been swallowed by the sun before the first round of calculations is done, but that

    doesn't mean reduction won't work.

    Note, this assumes a materialistic universe. The mind-body problem is a

    classic philisophical debate, I could go on for hours. Science usually takes the materialist position, but not

    always. One theory of quantum physics suggests that the ethereal mind affects the physical body by influencing how

    the wave function collapses in a brain event.

    This conversation has gotten away from how the VNO works, but I

    found a few articles that might be relevant.

    They all

    apply to moths, and I'm not sure how well moth anatomy can be applied to humans. But if I read these abstracts

    right, it takes a certain combination of nerves to be stimulated for a pheromone to be registered.

    Another

    piece of the mystery uncovered?
