Fair warning: This entry will talk about sex. Why am I telling you this time? Not sure.
So, some scientists wanted to see what orgasm looks like - from a neurological perspective, of course. So, they stuck folks inside PET scanners and watched the results. So the sensory bits (yes, that's a technical term) - the parts that register touch, light up. The other parts of the brain - thee parts that register tension, stress, judgement, decision making, inhibition, fear and anxiety all stop. This happens to a far greater extent in females as compared to males. So, women turn off their emotions during sex.
