What: Towards the investigation of neuronal processes underlying continuous speech processing

Where: BCBL auditorium

Who: Mathieu Bourguignon, Université libre de Bruxelles

When: 12 noon


Speech communication represents a major component of human social interaction. Up to now, most studies addressing the neural basis of human speech communication have used highly controlled vocal or verbal stimuli. Such approaches are surely appropriate for studying the neuronal underpinnings of specific aspects of speech comprehension and production. However, evolving towards more naturalistic speech paradigms would help to further characterize the neurophysiological correlates of speech processing in everyday interactional situations. This talk will deal with magnetoencephalographic recordings of healthy subjects during continuous speech listening. Two analysis methods will be presented (coherence analysis and canonical correlation analysis), as well as their yielded insight into brain processing of prosodic rhythmicity at the sentence level and into spectral brain dynamic associated to continuous speech processing.
