English: " Effect of (S)-CE-123 and R-modafinil on dopamine transmission in the IL/PrL cortex. Graphs showing the effects of (S)-CE-123 (left) or R-modafinil (right) on dopamine levels in the IL/PrL cortex. The arrow indicates i.p. injection of (S)-CE-123 or R-modafinil at the dose of 1 mg/kg (blue), 5 mg/kg (green), 10 mg/kg (red) or vehicle (black). Results are presented as mean ± SEM of change in dopamine extracellular levels expressed as the percentage of basal values. Solid symbol: p < 0.05 with respect to basal values; * p < 0.05 (S)-CE-123 10 mg/kg vs. vehicle; § p < 0.05 (S)-CE-123 10 mg/kg vs. (S)-CE-123 1 mg/kg dose; # p < 0.05 (S)-CE-123 5 mg/kg vs. veh; ° p < 0.05 R-modafinil 10 mg/kg vs. (S)-CE-123 10 mg/kg ((S)-CE-123 n = 21; R-modafinil n = 12). Three-way ANOVA, Tukey’s post hoc. "
