Research using[14] brain-scanning technology found that stimulating nipples in women resulted in the activation of the genital area of the sensory cortex. The research suggests the sensations are genital orgasms caused by nipple stimulation, and may also be directly linked to "the genital area of the brain".[14][15] In women, one study indicated that sensation from the nipples travels to the same part of the brain as sensations from the vagina, clitoris and cervix. Nipple stimulation may trigger uterine contractions, which then produce a sensation in the genital area of the brain.[14] Thighs In 2012, the California Institute of Technology[16] measured brain responses in heterosexual males as they were having their inner thighs touched whilst being MRI scanned.
