(A) Representative sIPSCs traces recorded from putative VTA DA neurons before (Baseline), during LY2817412 (1 μM), and during picrotoxin (100 μM) slice perfusion. Scale bars: 50 pA × 2 s. (B-C) Bar graphs showing the effects of LY2817412 (1 μM) on frequency (D) and amplitude (E) of sIPSCs. (D). Representative mIPSCs traces recorded from putative VTA DA neurons before (vehicle), during TTX (1 μM), TTX + LY2817412 (1 μM), and during TTX + LY2817412 + picrotoxin (100 μM) slice perfusion. Scale bars: 50 pA × 2 s. (E-F) Bar graphs showing the effects of LY2817412 (1 μM) on frequency (D) and amplitude (E) of mIPSCs.
