Figure 2. The sensitivity and operational range of rod-driven DBC responses are regulated by GABACR.
(A) ERG recordings from WT and GABACR−/− mice under dark- and light-adapted conditions. (B) ERG b-wave sensitivity plots for the following mice and conditions: WT, GABACR−/−, WT injected with the GABAAR antagonist SR-95531, WT injected with GABACR antagonist TPMPA, D1R−/− injected with TPMPA. (C) ERG recordings from dark- or light-adapted WT and D1R−/− mice with and without GABA injections. (D) WT and D1R−/− ERG b-wave sensitivity plots in the absence or presence of injected GABA.
