Guess where the most blood flow goes?
Curious to draw a roadmap of what happens in the brain when we masturbate, new scientist writer Kayt Sukel decided to lock herself up in a fMRI scanning machine while pictures of the good times starting to manifest themselves…
gawker: Sukel worked with Rutgers University researcher Barry Komisaruk, who’s studying brain response during arousal and orgasm. Komisaruk has found that when many women achieve climax, their prefrontal cortexes (which are thought to govern “executive function” like decision-making) see increased activity. Its involvement, in particular when touches are imagined rather than felt, may indicate the use of “imagination or fantasy,” as well as the ability of the brain to perform so-called “top-down” control over the body.
Somehow as a man, I’d be curious to see how much deviation one would be able to discern to the degree of blood flow to the brain- especially as men we are hardwired to visuals as opposed to the impression of touch and sultry seduction.
But the PFC isn’t the only part of the brain that’s active — as you can see, Sukel’s brain saw activity in some 30 areas, “including those involved in touch, memory, reward and even pain.” Interestingly, another study of orgasm examined by fMRI showed decreased activity in the PFC. The difference between the two studies? Komisaruk’s investigated orgasm by self-stimulation, while the other featured subjects brought to climax by their partners — indicating that their may be a difference in how the brain functions in those difference scenarios.
Which forces this author to wonder how different would the images appear if it came to same sex climax or same sex fascination?
Either way, don’t leave home without a dash of lube…
