Perfusion of the basal membrane of the ampullae of Lorenzini with high potassium solution caused a substantial increase in the resting firing rate. This effect was not accompanied by any change in the threshold of the afferent fibres. The low potassium solution caused a decrease in the resting firing rate. When synaptic transmission was abolished by high Mg2+ solution, succeeding perfusion with 10 mM K+ did not induce responses in the afferent fibres. The role of potassium ions in the activity of the ampullae of Lorenzini is discussed.
