MNTB neurons from Fmr1^−/y mice fire more action potentials in response to repetitive stimulation. A, Current-clamp recordings of action potentials in response to repetitive stimulation with brief current pulses (1 nA, 0.3 ms, 20 stimuli) applied at rates from 50 to 600 Hz. B, Group data showing that MNTB neurons from Fmr1^−/y mice fire more action potentials at all stimulus frequencies up to 400 Hz. Asterisks indicate significant differences (two-way ANOVA followed by Holm–Sidak post-test).
