Rod BC light-evoked inhibitory postsynaptic currents (L-IPSCs) are significantly decreased by adaptation with a rod-saturating light. A: example L-IPSCs in response to the maximum light intensity (30-ms light stimulus) used from rod BCs in a dark-adapted retina and with a rod-saturating background (dark gray bar shows timing of light stimulus). B: the charge transfer (Q) of L-IPSCs in response to many intensities of light was normalized to the response at the maximum light intensity in dark-adapted conditions. L-IPSCs in light-adapted conditions were significantly decreased at all intensities used (*P < 0.01, n = 6).
