Fig. 4.
Two components of the evoked postsynaptic current.A, Postsynaptic currents were recorded from a GLC maintained at various potentials by applying depolarizing pulses (from −81 to −31 mV for 15 msec; top trace) to a bipolar cell. The holding potential of the GLC is indicated at theleft of each evoked current trace (lower five traces). The traces were shifted arbitrarily for a better view.B, The amplitude of the evoked postsynaptic current was measured at 12 msec (open circles) and 50 msec (filled circles) and is plotted against the holding potential of the GLC.
