Modulation of Brain Rhythms in Stroke

For each grip trial (20 grip trials per block), participants will receive visual cues that signify the onset and offset of squeezing. Just prior to the start of the visual cue representing the onset of squeezing, participants will receive a burst of repetitive transcranial magnetic stimulation (rTMS) to their primary motor hotspot region. Motor brain stimulation will involve 3 bursts of 5 pulses/burst with a 20 Hz inter-pulse interval delivered at 90% of their resting or active motor threshold.
