Gregory Cogan
Assistant Professor in Neurosurgery

Dr. Cogan's research focuses on speech, language, and cognition. This research uses a variety of analytic techniques (e.g. neural power analysis, connectivity measures, decoding algorithms) and focuses mainly on invasive human recordings (electrocorticography - ECoG) but also uses non-invasive methods such as EEG, MEG, and fMRI. Dr. Cogan is also interested in studying cognitive systems in the context of disease models to help aid recovery and treatment programs.

Current Research Interests

Human electrophysiology (ECoG, µECoG, EEG, MEG), speech perception, speech production, working memory, sensory-motor integration, neuronal speech representations, language processing, relation between neuroscience and cognition, neuronal networks, neural decoding, epilepsy

Current Appointments & Affiliations

Assistant Professor in Neurosurgery, Neurosurgery, Clinical Science Departments 2021
Assistant Professor of Neurology, Neurology, Epilepsy and Sleep, Neurology 2021
