DISC1 overexpression increases mIPSC amplitude and GABAAR current density in cultured cortical pyramidal neurons.
A, cumulative plots of mIPSC amplitudes in neurons transfected with GFP or FL-DISC1. Note that DISC1 overexpression caused a rightward shift in the distribution of mIPSC amplitudes, indicative of an increase in the sizes of mIPSCs. Inset, representative mIPSC traces. B, summary (mean ± S.E.) of mIPSC amplitudes and frequencies in neurons with different transfections. *, p < 0.05; Student's t test. C, representative whole-cell GABAAR current traces in neurons transfected with GFP or FL-DISC1. D, summary (mean ± S.E.) of GABAAR current density in neurons with different transfections. *, p < 0.05; Student's t test.
