Most of these approaches define a conscious brain as an integrated brain, where groups of cells in many different regions activate to form a cohesive pattern, explains Marcello Massimini, a neurophysiologist at the University of Milan in Italy. “But that’s not enough,” he says. Sometimes even an unconscious brain looks highly integrated. For example, stimulating the brain of a sleeping person can create a huge wave of activity that “propagates like a ripple in water.” It’s a highly synchronized, widespread pattern, but it’s not consciousness, he says, and so this measure is often unreliable for diagnosis.
