Rapid recovery of basal GABA release after the end of MPA treatment. GABA release determined by in vivo microdialysis at day 7, day 8, and day 9 after minipump implant in four animals. Day 7 is the last day of minipump delivering MPA. GABA release at day 7 is significantly lower than at days 8 and 9; the latter two do not differ (one-way repeated-measures ANOVA, ^#p < 0.05, post hoc Holm–Sidak test). In the comparison with control cortex (N = 7 animals), only GABA release at day 7 is significantly different (one-way ANOVA, *p < 0.002, post hoc Tukey's test). Error bars represent SEM.
