Cognitive Neuroscience of Human Verbal Communication
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 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.
We are looking for motivated students at Bachelor’s, Master’s and PhD levels to start in November 2021 or later. If you are interested in joining, please get in touch! For funded PhD positions, see more details here.
