[Activity of isolated interneurons of the pedal ganglia of the pteropodal mollusk].

Interneurons from pedal ganglia of marine mollusc Clione limacina continued their rhythmical discharges for many hours after isolation. A discharge frequency increased with depolarization of neurons and decreased with hyperpolarization. It is concluded that the endogenous activity of interneurons underlies generation of the locomotor pattern in mollusc pedal ganglia.
