Reversal Potential and Postsynaptic Receptors Governing Inhibitory Synaptic Input. A1, Cell-attached recordings of APs following a step change in light intensity (top) or pressure application of glycine (100 μM, 10 ms pulse; bottom) to the soma of each RGC type. The gray line above each trace plots light intensity (relative to darkness, shown schematically as the dashed black line). A2, Effect of glycine on voltage of each RGC type measured in perforated-patch recordings with gramicidin. B, Effect of the GABAA receptor antagonist bicuculline (BMI; 10 μM) and/or glycine receptor antagonist strychnine (Stry; 1 μM) on light-evoked inhibitory postsynaptic current (IPSC; Vm=+10 mV) in On (left column), Off transient (middle column), and Off sustained (right column) RGCs.
