Brain Pathology

Our goal is to combine mathematical models with brain recordings from patients to understand the origin of neurological diseases and disorders and suggest treatments

We want to explain the mechanisms and heterogeneity of neurological diseases and disorders. In recent work, we combined computational models with brain imaging data obtained from patients to understand the pathology of schizophrenia. Together with colleagues from Harvard, University of Minnesota, UCL and King's College, we are studying abnormal neuromodulation in patients with neurological disorders during perceptual and working memory tasks. Our work combines computational modeling, EEG, MEG and PET imaging. Our aim is to understand the origin of these disorders and explain their heterogeneity by grouping subjects into different clusters (biotypes).
