Dr. Chen’s research aims to understand how the brain recovers motor functions after a stroke, and to develop novel interventions that facilitate recovery. Her lab uses neuroimaging and noninvasive brain stimulation tools to understand how patterns of brain activity and connections are changed by stroke. This information can be used to predict an individual’s recovery potential.
Dr. Chen is also interested in the use of noninvasive brain stimulation and auditory feedback such as music to improve motor function. In particular, her group is interested in how the brain changes as a function of an intervention, which will give insight into mechanisms of brain plasticity.
The lab pursues research on motor skill learning in healthy individuals. Their work focuses on factors that can enhance and optimize skill acquisition, such as intensity and frequency of practice. The aim is to understand how learning occurs in people who have had a stroke.
Tools used are functional magnetic resonance imaging (fMRI), resting state fMRI, diffusion tensor imaging, transcranial magnetic stimulation and transcranial direct current stimulation.
