I will illustrate this bidirectional approach by focusing on Disorders of Consciousness (i.e.: vegetative states also coined unresponsive wakefulness syndrome, minimally conscious state and related conditions), but I will also address more briefly key recent findings in epilepsy, hemispherotomy and sleep.
