Cortex-wide variation of neuronal cellular energy levels depending on the sleep-wake states – Medical Xpress

It is assumed that the brain has homeostatic mechanisms to prevent the depletion of cellular energy, required for all cellular activities. For example, the blood flow increases, and oxygen and glucose are actively delivered in the brain region in which neural firing activity occurs. Besides, the cerebral blood flow and glucose uptake into the cells fluctuate accompanying the variations of cellular activities in the brain across the sleep-wake states of animals. Under these brain energy homeostat…
