Highly malignant and benign EEG patterns (adapted from Westhall et al. [58] and ACNS terminology [32]). A, B, C Figures represented EEG longitudinal montage showing highly malignant patterns. A Suppression, defined as suppressed EEG background (amplitude < 10 µV all the time of the recording) without discharges. B Suppression with periodic discharges, defined as a suppressed EEG background with continuous periodic discharges (spikes, poly-spikes, sharp or waves). C Burst suppression, defined as suppression periods (< 10 µv) constituting > 50% of the recording with “burst”. D EEG longitudinal montage showing benign EEG, defined as the absence of a malignant or highly malignant features namely continuous or nearly continuous and reactive EEG background. Blue line indicated the nociceptive stimulus (nail pressure), inducing amplitude and frequency modifications and defining reactivity when reproductible
