Abstract
A PROMINENT component of the electrical activity of the cerebral cortex is the surface negative potential lasting about 15 m.sec. It is evoked synaptically by stimulation of various corticipetal pathways (for example, the callosal fibres or optic radiations), antidromically on stimulating the corticifugal pyramidal axons, or by stimuli directly applied to the cortex. This long-lasting surface negative potential has been ascribed, on good experimental grounds, to electrogenic activity in the apical dendrites of pyramidal cells1.
