New research from Weill Cornell Medicine has found that this happens even during the times when the brain is at rest, and neurons are not firing their usual signals to one another. For instance, even during profoundly inactive states, such as coma, the brain’s consumption of glucose usually drops from normal by only about a half.  The scientists believe that the process of packaging neurotransmitters (chemical molecules used by the nervous system to transmit messages between neurons)...
