I have spent a good portion of the morning talking to my coworkers about the neuroscience of orgasm. There's a fascinating area of research on women who are paralyzed and numb from the waist down who can still experience orgasm. This appears to be due to the vagus nerve. The word vagus comes from the same root as vagabond, and the nerve is named for the way it "wanders" throughout the body instead of going to the spinal cord and taking the traditional route up to the brain. So when a woman is paralyzed, there is still a way for signals of pleasure to reach her brain and therefore her consciousness*.

In the process of looking up the article that documents this, I also found out that there's research showing that when people orgasm, there's a drastic decrease in activity in their prefrontal cortex. This makes sense, since experiencing an orgasm makes you feel "out of control". Similar research shows that some men and women who have trouble reaching orgasm fail to decrease prefrontal activity. Of course, it's hard to know what's causing what, but it seems to bear out the common wisdom that thinking too much about trying to come only makes it more difficult to do so.

My coworkers and I agreed that this would be a fun line of research to pursue, but that we'd get embarrassed trying to explain our jobs at parties, so it's for the best that we study something more mundane, like morality.


* - The actual mechanics of orgasm, especially in men, can be induced without any conscious awareness, kind of like a crayfish's swimmeret system. (I knew something seemed familiar!)
