mGluR activation increases the EPSCs in MCH neurons. A, DHPG (50 μm) increases sEPSCs. B, Mean effect of DHPG on the frequency or amplitude of sEPSC. Ctrl, Control. C, Little effect of DHPG (50 μm) on mEPSC in the presence of 1 μm TTX. D, Mean effect of DHPG on the frequency or amplitude of mEPSCs. E, DHPG (50 μm) effects on sIPSCs. F, Mean effect of DHPG on the frequency or amplitude of sIPSCs. G, DHPG (50 μm) exerts little effect on mIPSCs. H, Lack of DHPG effect on the frequency or amplitude of mIPSCs. The number of cells is shown in parentheses. Error bars indicate SEM. The asterisk indicates statistically significant.
