VTA dopamine depletion did not impair learning the simple reaction time task. Across days of learning in the simple reaction time task, the (A) rates of learning (%), (B) number of rewards, and (C) reaction times (ms) did not differ significantly between VTA-6OHDA animals and controls. Shaded areas represent SEM; control – black; gray – VTA dopamine depletion. + indicates a main effect of learning in a linear random-effects model. No consistent differences between VTA dopamine depletion and control animals were found.
