Stimulation of the surround linearizes inhibition to rabbit DSGCs. A and B: light-evoked inhibitory (A) and excitatory (B) conductances in a representative rabbit DSGC in response to narrow (200-μm width, left) and wide (900-μm width, right) bars moving at 400 μm/s in the null (top) and preferred (bottom) directions. Light-evoked conductances are shown for contrasts 10%, 20%, 40%, and 80%. C and D: contrast dependence of the integrated inhibitory (C) and excitatory (D) Off (left) and On (right) conductances in response to narrow (200 μm) and wide (900 μm) bars moving in the preferred or null direction at 400 μm/s; n = 4. The integrated light-evoked conductances were normalized to the predicted values at 100% contrast, evoked by a narrow bar moving in the null direction, and fit with the Hill equation.
