Verbal communication, in particular speech comprehension, relies on a combination of general auditory and speech-specific mechanisms, as well as on their interactions with multimodal and wide-spread neural networks that support other cognitive functions (e.g., attention and decision making). We study the cognitive and neural mechanisms that support language comprehension and verbal communication, in monolingual and bilingual individuals.
We are located at the Center for Integrative Neuroscience (CIN) at the University of Tübingen.
Methodologies: We use multiple electrophysiological methodologies, including whole-brain recordings using MEG and EEG, as well as intracranial electrophysiology in clinical settings (iEEG). This combination provides us with the unique opportunity to study human communication across neuronal scales: whole-brain neural dynamics in MEG, and submillimeter spatial resolution of intracranial recordings. Experimentally, we combine the analysis of continuous naturalistic stimuli with targeted hypothesis-driven task and stimulus designs.
Our paper on cortical auditory pathways is finally out in Cell! (in collaboration with Liberty Hamilton, UT Austin):
