Mecp2-null mice had larger muscimol-induced currents in the NTS. A. Example traces of muscimol-induced concentration-dependent current responses from one WT and one Mecp2-null mouse. Black bar indicates application of Muscimol. B. Group data of concentration-dependent response showing enhanced muscimol-induced currents in neurons recorded from the Mecp2-null mice (two-way ANOVA: p < 0.05, genotype; p < 0.05, concentration; p < 0.05, interaction). Numbers in parentheses indicate number of neurons. *, p < 0.05, Mecp2-null vs. FA, Fisher's LSD post-hoc test.
