Fig. 3A. Stimulation of cell SE1 (bottom trace) rapidly depolarizes and increases the firing frequency of cell 204 (middle trace). Note that swimming start s within approximately 0.5 s following stimulation of cell SE1. Vertical scal e bar pertains to the bottom two traces. B. In high Mg++ and Ca++ saline, each cell SE1 spike (bottom trace) is follo\ wed by a constant-latency EPSP in cell 204 of M11 and M12 (top two traces). Th\ e 2 mV scale bar pertains to the top and middle traces. Return to results
