This Just In: People Smell

SAPHRguru writes "New Scientist reports (10 Nov) that researchers may have taken a big step towards solving the mystery of how humans detect pheromones... we do it through our noses! Strange, I always thought I responded to chemical cues through my mouth (especially in brownies)!"

  1. No VMO in humans? by nlh · · Score: 4, Interesting

    Ok, I'm confused. According to the article:

    ...scientists have never been able to identify a VMO in humans, despite evidence that they do respond to pheromones.

    But that doesn't sound right. Believe it or not, I actually wrote a paper for my freshman psychology class back in Fall '96 on the effect of human pheromones and the VMO. At that time, at least, it was fairly well known that the VMO did indeed exist in humans, and that even its location in the human body was known (See this and this, for example).

    So when did it vanish from scientific literature, or was its existence called into question?

      Yeah, New Scientist made a hash of it.

      Humans have a VNO, but whether it works or not is a disputed question; there's both physiological and genetic reasons to believe that it's vestigial in humans, and possibly apes and Old World monkeys. If it is, then pheremones, which we know affect humans, must be detected by another system.

      So what the researchers in this case did was see if pheremones could cause reactions in the main olfactory system of mice. If they did (and they did), it explains how humans can be affected by pheremones despite a possibly vestigial VNO.
