Electrophysiological defects in gtx mutants. A, Representative EJP traces of wild-type, gtx
ex6, and gtx transgene expression in a gtx
ex6 mutant background using the T80 Gal4 driver. B, Representative voltage-clamp EJC recordings of wild-type and gtx
ex6 mutants. C–H, quantification of EJP amplitude (C), EJP decay time constant (D), EJC amplitude (E), mEJP amplitude (F), mEJP frequency (G), and EJC decay constant (H). n = 7 for all genotypes. **p < 0.001; ***p < 0.0001. Calibration: A, 2 mV, 40 ms; B, 3 nA, 15 ms.
