Mental Attitude: Standby Mode?

When the metabolic energy supply to brain cells is low (such as in comatose patients, in babies with serious neurodevelopmental disorders, and for a short period in some babies born prematurely) the brain enters a state called “burst suppression.” Researchers believe burst suppression is a type of intermittent standby mode, where cells remain inactive until metabolic energy levels increase enough to resume normal brain activity.
