We Are All Junkies

Courtesy the Science Blog: 'Thirst for knowledge' may be opium craving:

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...

...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.

The same mechanism is involved in the aesthetic experience, Biederman said, providing a neurological explanation for the pleasure we derive from art.

"This account may provide a plausible and very simple mechanism for aesthetic and perceptual and cognitive curiosity."

I'm totally going to have to track that down. So there may be more on this one later.
