Spatial reversal learning. Total distance moved in trials 1–9 of the reversal learning condition. Shown are group means and SEM error bars showing differences between groups in trials 4–6 [F(2, 38) = 6.74, P < 0.01]. Tukey post hoc analysis revealed a higher reversal learning performance of DBS On–On group compared to DBS On–Off [−1.03, 95% CI (0.27,1.78), P < 0.01] as well as DBS On–Off compared to controls [0.91, 95% CI (0.18,1.64), P = 0.01, ANOVA]. Trials 7–9 in which visible target served as motor control (Table 4). px, pixel; SEM, standard error of the means; DBS, deep brain stimulation.
