Figure 1. Characteristic state-dependent differences in electrophysiological activity.

(A) Representative EEG, EMG, and RMS EMG tracings across 8 s periods of wake, NREM sleep, and REM sleep from an individual rat. (B) z-scored electrophysiological features depict state-dependent variation in EEG and EMG activity. For complete description of EEG/EMG feature input to the neural network classifier, see “Methods”.
