Emotional and Neutral Sounds for Neurophysiological Prognostic Assessment of Critically Ill Patients With a Disorder of Consciousness

Summary

The purpose of this study is to determine if the use of emotional sound as subject own name (SON) pronounced by a familiar voice (FV) compared to SON pronounced by a non-familiar voice (NFV) during event related potential (ERP) produced a more reliable neurophysiological P300 responses, and to assess the prognostic value of this P300 responses induced by the SON with a FV.
