Language processing and recovery in aphasia
Aphasia affects over 35% of stroke survivors with the incidence of stroke rising as the aging population increases. The degree of language recovery in persons with aphasia depends on many stroke- and patient-related factors, but our understanding of the cognitive mechanisms and underlying brain networks that mediate this recovery remains limited. In this line of work (in collaboration with Swathi Kiran), we are characterizing linguistic and cognitive processing in the brains of individuals with aphasia and trying to understand how linguistic function recovers after brain damage.
How to study the brains of individuals with aphasia using brain imaging?
This paper discusses how the functional localization approach can be applied to research on aphasia.
Comprehension and production in aphasia through the lens of the noisy-channel framework
These papers argue that individuals with aphasia use available linguistic and other resources in a rational manner so as to maximize behavioral utility.
