A different stain marks nerve cell fibers (bottom), revealing heavy staining in the central region where nerve fiber tracts connect one region of the brain to another.

Most of this energy goes towards maintaining synapses, the junctions across which impulses jump from nerve cell to nerve cell, keeping the brain alert even when it is not doing anything.

"Stimulation of the cell by certain chemicals or by sensory receptor cells causes depolarization of the membrane, permitting an impulse to move along the nerve fibre (in nerve cells) or causing the cell to contract (in muscle cells). "
