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

"Use of expressive sounds, that is to say the own first name pronounced by the voice of the relative to generate the P300 and a sound with an approaching character of the subject to generate the MMN.~The investigators will thus be able to compare:~* MMN: present/absent for each modality (neutral vs approaching sounds)~* Wave P3a: latencies and amplitudes for each modality (own first name voice of the near vs unfamiliar)."

"Retrospective inclusion Have already had an assessment with event related potentials without emotional modalities (VF and similar sounds) as part of their care between April 2022 and December 2022 in intensive care at Cochin hospital."
