Neurological prognosis for comatose patients resuscitated after cardiac arrest remains challenging. Functional imaging suggests that altered connectivity of the brain’s default mode network (DMN) could predict poor outcomes. Unfortunately, functional imaging is not easily applicable at the bedside.We proposed a neurophysiological method that assesses DMN function by computing the default EEG reactivity (DER). The method maps continuous EEG to a sequence of recurring oscillatory patterns termed macrostates. We labelled the default EEG macrostate (DEM) as the macrostate with the lowest probabili
