A, GABA-evoked currents (IGABA) were recorded from wild type, dnc1 and rut1 pupal MB neurons before and after perfusion of 2µM FSK. 100µM GABA was focally applied for 2 seconds as indicated. B, Percent amplitude of IGABA in pupal MB neurons after perfusion of FSK. C, Percent amplitude of IGABA in embryonic MB neurons after perfusion of FSK. Bar = SEM. Students t-test, **P< 0.01 and ***P< 0.001. Number of replicates: Wt (n=6), dnc1 (n=6), rut1 (n=6).
