a Schematic representation of the sleep recording. Pallidal local field potentials are recorded in parallel to the polysomnography consisting of the electroencephalogram (EEG), electrooculogram (EOG), and electromyogram (EMG). In the morning after sleep recording, a 5-min recording of resting wakefulness is further obtained. b shows 10 s of characteristic N2 sleep from subject PD-8, epoch 26. Characteristic sleep spindles are seen in polysomnography. Note that for visualization, the amplitude of the pallidal channels is amplified. c shows 10 s of characteristic REM sleep from subject PD-8, epoch 16. Prominent rapid eye movement, low-voltage waves, and muscle atonia are seen in EOG, EEG, and EMG, respectively. d shows a representative spectrogram of a whole-night recording from subject PD-8 with the hypnogram on top. e shows the average power spectra across awake, NREM, and REM sleep epochs in all patients with Parkinson’s disease. f shows the average power spectra across awake, NREM, and REM sleep epochs in all patients with dystonia. Shaded areas represent SEM. Theta and beta frequency band ranges are highlighted in blue.
