(A) Voltage responses of a medium-field, transient ON-OFF AC (tON/OFF-AC) elicited by whole-field light step (-3, 500 nm) and by a center light spot (300 μm) and a surround light annulus (700 μm inner diameter, 2,000 μm outer diameter) recorded from dark-adapted salamander flatmounted retinas. ΔS of this AC is 1.35. (B) Fluorescent micrographs of the AC soma and dendrites (confocal images of the inner INL and IPL) stained with neurobiotin (green) by 10-minute dye injection. Dendritic field diameter is 687 μm. Calibration bar: 100μm. (C) Voltage responses of the AC to a light bar moving stepwise (with 120 μm step increments) across the receptive field. The receptive field diameter (RFD) is 704μm. (D) Voltage responses to a moving light bar in the x and –x directions.
