i found an interesting post I thought anout neuroscience that I would share:
"Brain differences by gender"
I am sure my earlier posts were more clear than you are making out. But let us say I have not been as precise as I ought in describing just one major difference in the brains of men and women. I will try for the final time and if I still cannot make myself clear I must move on. Believe me, this is one of a whole world of physical differences.
The medial preoptic area of the hypothalamus is the centre of male sexual behaviour. It receives signals from 2 nuclei in the amygylda (since you ask: corticomedial and basolateral). These produce the aggression/assertive behaviour visible in aroused males (male monkeys as well as humans). They also produce the aggressive/assertive behaviour seen in males in general but are stoked by sexual arousal. The signals continue to the cerebral cortex which will then force the male to adopt whatever position is necessary to penetrate the female. This is why guys can have a tough time pulling back if the female changes her mind at the point of entry. A signal is sent down the brain stem to the penis thus engorging it. A signal is sent back to the brain to create more of the hormones leading to aggression. This loop then intensifies until ejaculation. The male gets more aroused and more aggressive.
Intriguingly the female centre for sexual behaviour is found in the ventromedial nucleus, again in the hypothalamus. Curiously it plays a part in hunger too. This is where feminists need to look away. These oestrogen rich hormones, (thus not even available to the male) produce lordosis, a need for the female to expose herself sexually and submit. In humans this instinct has more conscious control than say in rats where by simply handing the female rate in a particular way will lead to lordosis. Again the loop is established leading to more arousal in the brain and more excitement in the female body leading to ever greater passivity.
What is truly fascinating is that this sexual arousal permeates all aspects of the brain, even into the frontal cortex, where it is believed fetishes, so loved by humans, develop.
