Sexual desire, as well as orgasm, are controlled by various influences on the brain and nervous system. Researchers have revealed many similarities between men and women; contrary to popular belief, for example, visual stimuli spur sexual stirrings in both.
Brain imaging studies show that achieving orgasm involves far more than merely heightened arousal. It requires a release of inhibitions, culminating in a shutdown of the brain’s center of vigilance in both sexes, and a widespread neural power failure in women.
The fascinating Scientific American article linked below explores the body of research on this compelling and universal subject.
