Figure 2. Latencies of Ca2+ and RA in gating HGJ channels of an H-1 type horizontal cell
A: Pipette tip potential was measured after the whole cell recording to establish the rise time of application. B: An outward current in Ca2+ free solution was reduced by 2 mM Ca2+ without a measurable delay. C: After washout in B, 30 mM at-RA reduced the outward current with a 160 ms delay. The cell was held at 30 mV.
