Abstract(in English) | To elucidate the properties of the light-induced response of the retinal on-off amacrine cell, we made intracellular recordings with special attention to the dendritic action potential. We analysed the responses of fast on-off amacrine cells to a red spot of light placed at different distances from the recording cite and found, 1)the amplitude of the response decreased with the distance, 2)the response delay increased with the distance, 3)the rising time was almost constant regardless of the distance, and 4)the response to spots of light illuminated at a shorter and a longer distances simultaneously was similar to the one induced by the spot at a shorter distance and was not a sum of the responses to both spots. These suggest the nonlinear properties in the spatial propagation of the on-off response of the retinal amacrine cell. |
