Komisaruk hopes his research will help people who can't reach orgasm. "That is the big question."įor the record, while eroticism is a mystery, Komisaruk and his lab team found that an orgasm involves a variety of brain regions, including the hypothalamic paraventricular nucleus amygdala accumbens-bed nucleus of the stria terminalis-preoptic area hippocampus basal ganglia cerebellum the anterior cingulate, insular, parietal and frontal cortices and the lower brainstem. "Are there particular brain regions that have to be activated in order for genital stimulation to be converted from run-of-the-mill stimulation versus stimulation with an erotic quality?" he said. That leaves the question of what makes a sensation erotic, Komisaruk said. The women in the study (each of whom was paid $100 to participate) were not necessarily turned on by the self-stimulation in the fMRI scanner even so, using a similar setup in an earlier study, Komisaruk and his colleagues were the first to locate the female orgasm in the brain. One of his graduate students is further testing the idea by studying the response of women who have had a hysterectomy, meaning their uterus has been removed. A few men who have been studied show the same pattern of nipple stimulation activating genital brain regions, Komisaruk said. However, preliminary data suggest that nipple nerves may directly link up with the brain, skipping the uterine middleman. 6,3K views 58,0 05:22 Slim porn model plays with her clitoris in style. 1,9K views 57,7 00:35 Tight Belgian girl showing off her body. 11,8K views 60,7 10:47 Fat old Belgian tart playing with her cunt.

So it's possible, Komisaruk said, that nipple stimulation triggers uterine contractions, which then produce a sensation in the genital area of the brain.

One is indirect: Stimulating the nipples, as in breast-feeding, releases the hormone oxytocin. There could be two reasons for this, Komisaruk said. Nipple stimulation showed up in the area of the brain that receives chest sensations, but it also popped up alongside the genital sensations in the medial paracentral lobule, the researchers found.
