For discussing the functions of different structures of all organisms.
i want to ask that when a boy and a girl come close to each other not all of them feel attractions for oneanother.......i mean a boy may be attracted toward a girl,even if she has ordinary looks,,,,,but may b he is not atrracted to a charming lady....?is it due to some hormones??
hormones may cause a general attraction, but i don't think they would cause an attraction to a specific person, over another
I would venture to guess that this is one of those "not-well-understood" areas of the brain
It would be interesting to find out what exactly causes specific likes and dislikes

That's what commonly said as "chemical"
In birds, it involves the functional pineal body, which will process the visual signal from eyes. Shortly, this will lead to reproductive season.
In mammal, including human, pineal body is not developed well. So I still have no idea of this "chemical"
i don't knwo either, but if they ever put it in bottles, they will make a fortune.

Yap...human sex pheromone...bottle it and we (men) will make a great fortune...
Um, by the way, human also have sex pheromone isn't it? I think I've read that women usually secrete sex pheromone during ovulation period...
Q: Why are chemists great for solving problems?
A: They have all the solutions.
@victor: The smell of women caused by aromatase. In their ovulation period, the estrogen level is the highest, in that time aromatase is plenty, because it is needed to convert androgen (testosteron) to estrogen. Their smell can be caused of that. BUT, it could be from something else, because in the period, women producing more sweat and (sorry) the blood things. If they don't clean their body well, so they produce bad smell. This is hygiene stuff
@hbeing: odor = body smell
And there is some connection between smell and differences in their genom. Had a lecture of this a couple of years ago...
Women smelled at t-shirt used by different men, and the researcher found out that they preferred the smell from the men that had hla-genes (MHC, the thing antigens are presented on) that was most different from their own.
(evolutionary good to increase the genetic variation...).
