It's what women have been telling men for decades: stimulating the vagina is not the same as stimulating the clitoris. Now brain scan data has added weight to their argument.
The precise locations that correspond to the vagina, cervix and female nipples on the brain's sensory cortex have been mapped for the first time, proving that vaginal stimulation activates different brain regions to stimulation of the clitoris. The study also found a direct link between the nipples and the genitals, which may explain why some women can orgasm through nipple stimulation alone.
Some have argued that women who derive pleasure from vaginal stimulation do so because their clitoris is being indirectly stimulated, but the current findings contradict this. "They support the reports of women that they experience orgasm from various forms of stimulation," says Beverly Whipple, also of Rutgers University, who was not involved in the current study.
Komisaruk also checked what happened when women's nipples were stimulated, and was surprised to find that in addition to the chest area of the cortex lighting up, the genital area was also activated. "When I tell my male neuroscientist colleagues about this, they say: 'Wow, that's an exception to the classical homunculus,'" he says. "But when I tell the women they say: 'Well, yeah?'" It may help explain why a lot of women claim that nipple stimulation is erotic, he adds.
Something that tends to cheese women off : having male doctors tell them what they must be feeling, when said male doctors have no actual evidence to back up what they say.
Next time, believe her, OK doc? Because the MRI images show that your arrogant ideas aren't actually true, as any woman could have told you - and female medical professionals probably did, you just ignored them.
On a personal note, it's obvious my neural anatomy (in this area at least) is strongly female, and always has been. It's good to have the peripherals match the device drivers at last. That's all I'm saying on the subject.
