Fig. 5. Differences in electromotor neuron (EMN) output patterns in response to L-glutamate (L-Glu) iontophoresis in the dorsal posterior (DP) and precommand nuclei (PCN). Each row corresponds to a single fish. The three representative examples for each nucleus show an expanded view of the period from 31 s to 34 s of the data shown in Fig. 4.
