PANEL A: 2 channels sensors (BIS Quatro) connected to a Philips module: real time EEG shows polyspikes (white star), spikes (white arrow), and spike-wave (red arrow). IQS = signal quality index. RS= suppression ratio. PANEL B: 2-channel sensor (BIS Quatro) connected to a BIS VISTA module: real time EEG shows spike-wave (red arrow) and spike (white arrow). IQS = signal quality index. RS= suppression ratio.

One hour later a 13 channels EEG (Figure S1 in supplementary figures) diagnosed a NCSE as a pattern of generalized periodic spike-waves evolving in generalized rhythmic spike-waves at 1 Hz with high amplitude (> 200 microV), without response to stimulation.
