if there's a such thing as a professional opium smoker, this kid is going to be one in a few short years.
neuroscientists have proposed a simple explanation for the pleasure of grasping a new concept: the brain is getting its fix.
the "click" of comprehension triggers a biochemical cascade that rewards the brain with a shot of natural opium-like substances, said irving biederman of the university of southern california. he presents his theory in an invited article in the latest issue of american scientist.
"while you're trying to understand a difficult theorem, it's not fun," said biederman, professor of neuroscience in the usc college of letters, arts and sciences.
"but once you get it, you just feel fabulous."
the brain's craving for a fix motivates humans to maximize the rate at which they absorb knowledge, he said.
"i think we're exquisitely tuned to this as if we're junkies, second by second."
biederman hypothesized that knowledge addiction has strong evolutionary value because mate selection correlates closely with perceived intelligence.
only more pressing material needs, such as hunger, can suspend the quest for knowledge, he added.
