A two-way repeated measures ANOVA demonstrated a significant effect of concentration [F(1.166, 24.49) = 256.0, p < 0.001] and a significant treatment × concentration interaction [F(8, 84) = 2.216, p = 0.034] with a nearly significant effect of treatment [F(2, 21) = 3.350, p = 0.055] on inhibition of DA uptake ( Figure E).
