Brain scans reveal human pheromones

More and more scientists believe that people, like insects and other animals, give

off pheromones. Such scents covertly influence the behavior and physiology of

other members of a species, particularly of the opposite sex (SN: 3/14/98, p.

164: http://new.sciencenews.org/sn_arc98/3_14_98/fob1.htm). A research team reports in the Aug. 30 Neuron that the brains of men and

women respond differently to two putative pheromones, compounds related to the

hormones testosterone and estrogen.
