Figure 1.
Effects of 1 μM (A) and 100 μM (B) Zn2+ on the current responses to 100 μM glycine in retinal ganglion cells. In each case, current responses were recorded under voltage-clamp conditions at a holding potential of 0 mV. Glycine-induced currents in control Ringer’s solution were presented as trace a, and currents in Ringer’s solution containing 1 μM (A) or 100 μM (B) were shown as trace b.
