Popis: The negative potential shift in response to tetanic stimulation of the surface of the cortex or thalamic nucleus was recorded from the cortical surface in cats lightly anesthetized with pentobarbital. Parallel intracellular recordings were obtained of activity of neurons and glial cells. Glial cells responded to this stimulation by slow depolarization, which, under certain conditions of stimulation, was followed by slow hyperpolarization; hyperpolarization shifts were observed in neurons. Depolarization and hyperpolarization of glial cells, like hyperpolarization of neurons, did not correlate in time with the development of a negative shift of the surface potential. It is postulated that this shift is a response of complex origin involving the participation not only of glial cells, but also of cortical neurons.
