spreading depression

a propagating wave of silence in neuronal activity accompanied by a relatively large negative electric potential. Spreading depression occurs in regions of gray matter, including the cerebral cortex and hippocampus. It may occur spontaneously or be evoked by intense local electrical, chemical, or mechanical stimuli. Cortical spreading depression is related to migraine headaches.
