Neurorehabilitation in semantic aphasia
Lead researcher: Professor Beth Jefferies, Department of Psychology
People with aphasia often have problems with comprehension following a left-hemisphere stroke. These difficulties typically reflect poor regulation of retrieval to suit the current context or goals, as opposed to degraded knowledge.
Our work has been making sense of these deficits by finding out what helps and hinders semantic retrieval in people with aphasia, and how comprehension relates to changes in brain networks. This work is supported by convergent studies of the neural basis of semantic control in healthy participants.
