Interneuron activity in SubEG-T preparations. a Trigger neuron Tr2 depolarization triggers and subsequently terminates swimming. b Excitatory drive neuron, cell 208, is depolarized during swimming with superimposed large-amplitude membrane potential oscillations. c Swim-gating neuron, cell 204, is tonically depolarized during swimming. In each record, the lower trace is an extracellular DP nerve recording; the upper traces are intracellular penetrations of the neurons indicated. Except for the prolonged swimming, these records are similar to those recorded in H-T or M2-T preparations
