How Anesthesia Switches Off Consciousness

A computer model of a network of neurons shows that a sudden breakdown in the net's ability to transmit information mimics the brain wave changes that accompany anesthesia. http://physics.aps.org/articles/v8/85 Brent -- You received this message because you are subscribed to the Google

into the whole thing. But why does anesthesia just disrupt consciousness? Most anesthetics subtly disrupt the operation of neurons so that their signals don't travel as far or as reliably across the brain. Thus the complex signaling across distant brain regions may be cut off
