Effects of sleep on cortical PAC. (A) Examples of MI maps observed in the SMA of monkey A, during periods of wakefulness and sleep (from the same day) at baseline. (B) Spectral analysis of the SMA of monkey A, during periods of wakefulness (blue) and sleep (green) in the normal stage. (C) Sum MI values during sleep in the pre-MPTP phase (means + SEM; *P < 0.05; **P < 0.01; Wilcoxon signed rank test). (D) Sum MI values during periods of sleep across baseline and stages 1–3 of parkinsonism in monkeys A and B, and in baseline and stage 3 parkinsonism in monkey C. Comparisons between the baseline and the 3 stages of parkinsonism with a nonparametric one-way ANOVA on rank did not yield differences. #P < 0.05; Mann–Whitney test for significant difference between the normal state and stage 3 parkinsonism.
