Topic: phase-locking value

The first days of post-cardiac arrest (CA) coma represent a volatile yet underexplored state, as neural functions drastically change over time. Previous literature has shown that bodily functions of patients fluctuate within a day, some of which follow circadian rhythms. The information content of electroencephalography (EEG) activity, such as Lempel-Ziv complexity (LZc) or the slope of the 1/f-power decay can differentiate between levels of consciousness, while the phase-locking value (PLV) in the first 24 h of coma is predictive of patients’ outcome. Yet, it remains unknown how these measure
