In a magazine called
Scientific American
Mind (http://www.sciammind.com/article.cfm?&articleID=792DDD7C-E7F2-99DF-397429B8BB8ED7ED), a sister publication of Scientific American has in it's current edition an article on
"Cranial nerve 0". Unfortunately, you have to pay to read the article, but what it basically says is that this
particular nerve replaces the VNO. Nerve "0" begins at the nose and follows a path similar to the olfactory nerve,
except it terminates in the regions of the brain associated with sexual response rather than scent. Further, when
stimulated in a fish, it triggers the immediate release of sperm. Might be interesting to find a copy in a book
store or library. It's the March/April issue and the story begins on page 20.

As mentioned in my
post to this forum section on Feb 13...
Sex and the secret nerve
"Although some scientists claim to have
detected an operational vomeronasal organ in humans as well, most believe that it appears to be vestigial. As is the
case with gill slits, we possess vomeronasal organs only during our fetal lives, after which they atrophy. So if
pheromones are sending sexual signals to human brains, they are not relying on the vomeronasal organ to relay
them."
See the current issue at:
http://sciammind.com/
for a comprehensive review of
various approaches to the concept of human pheromones. It's much less technical than my recent review in the
Journal of Psychology and Human Sexuality, which may make it more valuable to a lay audience. The key connection is
to GnRH neurons (but that's more than most people need [want] to know). [as indicated by the lack of
discussion]

Sheesh a portable device to do that for
humans would sure as hell take a lot of the hassle and humbug outta dating. I could be in and outta there in a few
seconds.

I'm attending/presenting at an olfactory conference this week. Just noticed that an article I was interviewed for
is available at the following

I have a quick question,
Where is the " nerve zero" located?

It begins in the nose and follows the olfactory nerve until it
reaches the brain where it splits off and terminates in the part of the brain that handles sexual response (among
other things) rather than sense of smell.

Thanks for the
continued enlightment JVK.
Thanks also to MtnJim. I will add that nerve zero is linked to
gonadotropin releasing hormone release (GnRH)--a key issue when it comes to human chemical
communication.
From my recent review:
... according to Boehm, Zou & Buck (2005):
“The fact that GnRH
neurons are the master regulators of reproductive endocrine status indicates that pheromone effects on reproductive
hormone levels are ultimately mediated by these neurons. Indications that GnRH peptide plays an important role in
the control of sexual behaviors suggest that pheromone effects on these behaviors might also involve GnRH neurons
(p. 683).”
