Effect of strychnine and TTX on glycinergic inhibitory currents elicited by electrical stimulation. IPSCs were recorded from ganglion cells held at 0 mV to eliminate excitatory currents, and the control Ringer’s solution contained 150 μm picrotoxin to block GABA-mediated responses. Responses were elicited by 1 msec, 1 μA current pulses applied through a pipette located in the OPL directly over the recording site (A) and ∼300 μm lateral to the recording site (B). Superimposed traces show current recorded under control conditions (control), in the presence of 2 μm strychnine (STR), and in the presence of 500 nm TTX. A andB were from different cells. Holding current was 15 pA in A and 12 pA in B. Thedot below traces indicates time of electrical stimulation.
