Voltage responses of transient ON-OFF GC (tON/OFF-GC) elicited by whole-field light (-3, 500 nm) (A), and by a center light spot (300 μm) and a surround light annulus (700 μm inner diameter, 2,000 μm outer diameter) (B). (C) Fluorescent micrographs of the GC soma and dendrites (confocal images of the GCL and IPL) stained with neurobiotin (green) by 10-minute dye injection. Dendritic field diameter is 681 μm. Arrowhead: axon. Calibration bar: 100μm, arrowhead: axon. (D) Voltage responses of the AC to a light bar moving stepwise (with 120 μm step increments) across the receptive field. The receptive field center diameter (RFCD) is 2,170 μm. (E) Voltage responses to a moving light bar in the x and –x directions. (F) Response-intensity (V-Log I) curves of voltage responses to 500 nm and 700nm lights. ΔS is 2.5 for ON response and 0.8 for OFF response.
