Proceedings #15: Concurrent HD-tDCS/fMRI Study Exploring Changes in Motor Network Physiology and Complexity

Transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) can be an efficient way to modulate cortical excitability and promote motor recovery following stroke. However, the effects of M1 tDCS on behavior have been highly variable across individuals. Here we explored whether another motor region that is less often affected by stroke (dorsal premotor cortex, PMd) could also modulate cortical excitability. We also examined motor network neural complexity changes following stimulation of either M1 or PMd using simultaneous fMRI.
