The traditional approach to evaluate patients who survive severe brain injuries might fail to detect signs of recovery of consciousness and to better understand its neural correlates. Correlating the individual patient’s clinical evolution with behavioral, electrophysiological, neurophysiological and neuroimaging assessments can provide objective measures of recovery of consciousness and give an insight into brain functioning during this process. Taken together, these measures can provide useful hints about the neural mechanisms underlying the recovery of consciousness after brain damages.
