Consciousness and responsiveness: Lessons from anaesthesia and the vegetative state

Abstract

peer reviewedPURPOSE OF REVIEW: The aim of this article is to review recent behavioural and neuroimaging studies in anaesthesia and the vegetative state. RECENT FINDINGS: These studies highlight possible dissociations between consciousness and responsiveness in both these states. SUMMARY: We discuss future avenues of research in the field, in order to improve the detection of awareness during anaesthesia and the vegetative state using neuroimaging and neurophysiologic techniques
