Nicotine-elicited inward currents in MHbV neurons. A, MHbVL or MHbVC neurons were voltage-clamped at −60 mV, and nicotine at the indicated concentration was puff-applied. Representative traces are shown for each nicotine concentration and cell type. Calibration: 1 μm nicotine, 25 pA, 5 s; 30 μm nicotine, 0.5 nA, 5 s. B, Mean nicotine (1 μm) responses from MHbVL (n = 7) and MHbVC (n = 8) neurons are shown. *p < 0.05 (unpaired t test). C, Mean nicotine (30 μm) responses from MHbVL (n = 7) and MHbVC (n = 7) neurons are shown. *p < 0.05 (unpaired t test). D, Data from B and C are plotted together on a logarithmic scale. *p < 0.05 (unpaired t test).
