LP29: Considering transcallosal coherence as a marker of consciousness

Abstract

Results: The statistics did not reveal notable differences between MCSand UWS-patients. The comparison of DOC-patients and healthy subjects revealed statistical trends (p<0.05, uncorrected) in about 53.66% of the computed tests. We found an interesting pattern of common differences between DOC-patients and healthy subjects in a frequency of 6Hz. Conclusions: Transcallosal coherence of MCS- and UWS-patients seems not to differ systematically. Due to the differences of DOC-patients and healthy subjects, one might conclude that the impairment of DOC-patients is based on a common mechanism to a certain extent. The earlier mentioned interesting pattern of common differences might reflect a damage to frontal midline theta coherence which in turn might reflect an impairment of the working memory [3].
