Brain and Cognitive Disorders
The goal is to develop computational insight into how damage to the brain occurs and how it can be mitigated and repaired. Our work focuses in particular in disorders such as schizophrenia, aphasia, and amnesia, as well as visual and language impairments that result from damage to the system.
