Abstract: Interneuron 1 of the Melibe swimming CPG was studied with both intracellular and extracellular electrophysiological techniques. By varying the concentrations of Calcium and Magnesium in the extracellular saline, an oscillating voltage that happened in the absence of action potentials was observed in Interneuron 1. These results were taken to indicate that Interneuron 1 is driven at least in part by a wave of extracellular excitation.
