Abstract

After a train of impulses, the membrane potential of sensory neurons may be increased for several minutes by an electrogenic pump. During this hyperpolarization, the sensitivity of the membrane potential to external potassium ions is increased, so that physiologically occurring increases in potassium concentration could influence synaptic processes.
