Discussing the advances in the characterization of the cortical involvement in speech and hearing perception using magneto- and electro-encephalography.
Adrian K. C. Lee · The Journal of the Acoustical Society of America · 2011
Magneto- and electro-encephalography (M/EEG) are neuroimaging techniques that provide us with the high-temporal resolution particularly suitable to investigate the brain network involved in speech and hearing perception. In many of these studies, data are either interpreted at the sensor level (based on the magnetic/electric field recorded on the scalp) or at the cortical level (after making a judicious choice of the appropriate source modeling technique). There are unique challenges associated with each of these approaches in terms of data processing and, ultimately, making appropriate statistical inferences to illuminate the underlying neural mechanisms associated with the task under investigation. In this talk, the different technical challenges tackled in each of the studies presented in this session will be highlighted. Other methodological advances that are particularly relevant to experiments in the speech and hearing sciences will also be discussed.
