Minimally Conscious State (MCS) is a clinical condition characterized by reproducible, but inconsistent signs of consciousness. Fluctuations of responsiveness contribute to the misdiagnosis rate and prevent from effective interactions with MCS patients. These clinical fluctuations might also greatly limit the use of any Brain-Computer Interface (BCI) for communication purposes. The objective of the present study was to identify neurophysiological indices of responsiveness in MCS patients, investigating the connection between EEG background activity and the presence of a P300 ERP (Event-Related Potential) response to an oddball paradigm, considered a sign of higher level of responsiveness with respect to its absence.

Abstract
Minimally Conscious State (MCS) is a clinical condition characterized by reproducible, but inconsistent signs of consciousness. Fluctuations of responsiveness contribute to the misdiagnosis rate and prevent from effective interactions with MCS patients. These clinical fluctuations might also greatly limit the use of any Brain-Computer Interface (BCI) for communication purposes. The objective of the present study was to identify neurophysiological indices of responsiveness in MCS patients, investigating the connection between EEG background activity and the presence of a P300 ERP (Event-Related Potential) response to an oddball paradigm, considered a sign of higher level of responsiveness with respect to its absence.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
