It clears your brain, that's all. It's ain't related to some increase of IQ.
To put a scientific tag on this statement. It's the hormones. The reasons guys are known for thinking only of sex is because when you get that boner, your body tells you to do something with it. Since most of us are more than familiar with the aspect of pornography, it's the only thing we (men) can think about. Therefore, once you have properly done away with that hard-on, your once porno centered mind goes back to it's standard way of operating.
Therefore, you feel smarter after masturbation because the only thing you could think about for 5 or so minutes (give or take a few) was sexually arousing images/videos/scenarios/anything to do with sexuality.
I'm unsure if it may be the same for women, as I am not one, but I think it may be the same. Occlusion of your mental status when being turned on is only human nature. Why is it that you see so many young girls/boys (13-21) acting as they do (slutty/sex minded) at that age? Simple, instinct. It's natural for any animal to wish to propagate the species. So when the opportunity 'arises' (hehehe pun), nature says; "GO FORTH AND PROSPER". And at it's core, humanity is just another mammal. In fact, were it not for the fact that human pregnancy lasts so long (Nine months) we would be even more overpopulated than we are now. A sex drive is a lethal thing, even more so when it's implanted in something as dangerous as a human. Good thing it's only one baby a year for us eh?
I sort of veered off topic, but I think I thoroughly explained my train of thought
