Thanks for the lesson in neurology Grayness. A book that you might find interesting is Social Intelligence by Daniel Goleman. He states that men are more stimulated by visual clues where women are more into smell. It is a really interesting book full of studies and neurology terminology. He also talks about the high road and the low road of the brain. The high road is a lot slower and mainly in the neocortex and is more involved with responding where as the low road is a lot faster and mainly about reacting. It is a simple way of describing it though and there is not a black/white division as you know.
Psych medications do affect our sex lives. Most anti-psychotics block dopamine receptors. The biggest release of dopamine is when we have sex. There is also an inverse relationship between serotonin and dopamine. The more serotonin the less dopamine and vise-a-versa . That is why anti-depressants like Prozac that keep more serotonin floating around tend to lessen one's sex drive. I got all of that information from Dean Hamer's The God Gene. Also a very good book. ~Shoe
