| Neuroscientists trying to untangle the riddle of desire and sexual pleasure in the brain have discovered something that turns conventional wisdom on its head. Though most people believe that men are less emotional about sex than women are, the neurology of orgasm says otherwise, at least according to an intriguing article in Scientific American . During orgasm, men experience heightened activity in the emotion-processing centers of the brain. But women's brains, say researchers, are shut down in emotion-processing regions during arousal and orgasm. Scientific American 's Martin Portner writes: [Looking at the brains of orgasming men using a PET scanner] scientists also saw heightened activity in brain regions involved in memory-related imagery and in vision itself, perhaps because the volunteers used visual imagery to hasten orgasm. The anterior part of the cerebellum also switched into high gear. The cerebellum has long been labeled the coordinator of motor behaviors but has more recently revealed its role in emotional processing. Thus, the cerebellum could be the seat of the emotional components of orgasm in men, perhaps helping to coordinate those emotions with planned behaviors. The amygdala, the brain's center of vigilance and sometimes fear, showed a decline in activity at ejaculation, a probable sign of decreasing vigilance during sexual performance.
