Crossover creates an active antagonistic surround. (A) Original spatial profile of voltage responses for a population of ON bipolar cells in response to a bright stripe. The width of the stripe is shown in the dotted trace. (B) Voltage profile for an array of OFF crossover amacrine cells. (C) Inward current arriving at the ON ganglion cell from the ON bipolar cells. (D) Outward-going currents elicited at the periphery of the light bar. (E) Currents (C) and (D) add to generate an active inhibitory region in the periphery of the light bar in the ON ganglion cells.
