Functional connectivity describes the functional relationship between different regions of the brain. This research focuses on the use of noninvasive brain imaging modalities (fMRI, fNIRS, EEG) to track changes in functional connectivity over time, in particular we are investigating the use of resting state data to understand how the brain network changes without stimulus.
Current projects include longitudinal studies related to stroke patients and cochlear implant users.
Dynamic Functional Connectivity after Stroke
Our current work is investigating the longitudinal trends in dynamic functional connectivity of stroke patients. The first step in this has been to understand how dynamic functional connectivity changes in the normal course of aging .
Next we have looked at the reconfiguration of the functional brain network after stroke.
Static Functional Connectivity after Cochlear Implant
Despite hearing improving after cochlear implant, there are differences in the amount of improvement for each patient. We are using fNIRS to study the changes in functional connectivity during the first year after implantation.
