In search for intelligence, a silicon brain twitches

Dubbed Blue Brain, the simulation shows some strange behavior. The artificial "cells" respond to stimuli and suddenly pulse and flash in spooky unison, a pattern that isn't programmed but emerges spontaneously.

"It's the neuronal equivalent of a Mexican wave," says Dr. Markram, referring to what happens when successive clusters of stadium spectators briefly stand and raise their arms, creating a ripple effect. Such synchronized behavior is common in flesh-and-blood brains, where it's believed to be a basic step necessary for decision making. But when it arises in an artificial system, it's more surprising.
