Raw ERG waveforms for vehicle or drug-treated animals (a). Effects of vehicle and tonabersat on mixed a-wave and b-wave amplitude of the ERG using 0.26 mg/kg (b, e), 0.8 mg/kg (c, f), and 2.4 mg/kg (d, g) tonabersat. Vehicle data shown is at 2 weeks post-injury; in these animals, there is no recovery of ERG function. Statistical analysis was performed using a two-way ANOVA and a Bonferroni post hoc test. Significant values are indicated with asterisks: *p < 0.05; **p < 0.01; ***p < 0.001
