This is a one-visit study, in which right-handed participants (individuals with unilateral peripheral nerve injury to the right upper limb, and healthy controls) will complete surveys and perform movement tasks. Movement tasks will be performed inside and outside a magnetic resonance imaging (MRI) scanner.~Some participants will also receive transcranial magnetic stimulation (TMS) to briefly interfere with these putative brain networks.
The goal of this study is to determine which parts of the brain make it possible for some people to move skillfully with their left non-dominant hand.
