RESEARCH INTERESTS

The main research interest of the lab is the cortical basis of hearing and speech in humans. Two main questions are addressed. One concerns the specification of functional architecture of the speech perception system. This issue is studied using brain imaging as well as neuropsychological data. The second unifying theme in the lab is to investigate to what extent temporal mechanisms encode or represent information in the auditory cortex. We use non-invasive electrophysiological techniques (EEG and MEG) to explore how properties (such as latency variation or oscillatory activity) might provide a useful logistical framework to process or represent auditory patterns. The experiments use stimuli of varying complexity and ecological relevance, ranging from pure tones and FMs to ripples to syllables to words to connected speech. A third research topic that is extensively studied is lexical access. This topic and its various subtleties are investigated using a combination of behavioral and MEG studies.
