文摘

RGCs increase sensitivity under dim light by broadening spatiotemporal integration. We identified an antagonistic surround under scotopic conditions in a subset of RGCs. The center and surround differentially broaden temporal integration under dim light. Spatial alterations under dim light are more heterogeneous than temporal ones. Asymmetries between ON and OFF RGCs are decreased under dim conditions.
