Conditional knockout of Rac1 does not affect glycine and GABAA receptor-mediated inhibitory synaptic transmission in RGCs. A Representative recordings of glycine receptor-mediated mIPSCs in RGCs from control and Rac1-cKO retinal slices. B–E Summary data showing the frequency (B), amplitude (C), rise-time (D), and decay time (E) of mIPSCs in RGCs from control (n = 12) and Rac1-cKO (n = 10) mice. F Representative recordings of GABAA receptor-mediated mIPSCs in RGCs from control and Rac1-cKO retinal slices. G–J Summary data showing the frequency (G), amplitude (H), rise time (I), and decay time (J) of GABAA-receptor-mediated mIPSCs in RGCs from control (n = 11) and Rac1-cKO (n = 6) mice. **P < 0.01 vs control. The distribution of data in each cell was indicated as scattered circles and the data are expressed as medians and interquartile ranges.
