![]() The regions that were “significantly activated” during orgasm, the team found, included part of the prefrontal cortex, the orbitofrontal cortex, the insula, the cingulate gyrus, and the cerebellum. In a study of the female orgasm that was conducted last year, scientists from Rutgers University in Newark, NJ, monitored the brain activity of 10 female participants as they achieved the peak of their pleasure - either by self-stimulation or by being stimulated by their partners. ![]() “Our results correspond with reports of cerebellar activation during heroin rush, sexual arousal, listening to pleasurable music, and monetary reward.” The brain and the female orgasm The researchers liken the activation of the cerebellum during ejaculation to the pleasure rush caused by other activities that stimulate the brain’s reward system. Similarly, the secondary somatosensory cortex is thought to play an important role in encoding sensations of pain.Īs for the amygdala, it is known to be involved in the regulation of emotions, and dysregulations of its activity have been tied to the development of anxiety disorders.Īn older study from the same university - which focused on brain regions that were activated at the time of ejaculation - found that there was an increase in blood flow to the cerebellum, which also plays a key role in the processing of emotions. The insula is a part of the brain that has been tied to processing emotions, as well as to sensations of pain and warmth. The scans demonstrated that stimulating the erect penis increased blood flow in the posterior insula and the secondary somatosensory cortex in the right hemisphere of the brain, while decreasing it in the right amygdala. ![]() The brain and penile stimulationĪ 2005 study by researchers at the University Medical Center Groningen in the Netherlands used positron emission tomography scans to monitor the cerebral blood flow of male participants while their genitals were being stimulated by their female partners. This led some researchers to liken sex to other stimulants from which we expect an instant “high,” such as drugs and alcohol. For both men and women, sexual stimulation and satisfaction have been demonstrated to increase the activity of brain networks related to pain and emotional states, as well as to the reward system. ![]()
