The strategy for the proposed research is to identify individual brain areas that contribute causally to retention by disrupting their activity with transcranial magnetic stimulation (TMS). Investigators will also use functional magnetic resonance imaging (fMRI) which will enable identification of circuit-level activity which predicts either learning or retention of new movements, and hence test the specific contributions of candidate sensory and motor zones. In other studies, investigators will record sensory and motor evoked potentials over the course of learning to determine the temporal order in which individual sensory and cortical motor regions contribute. The goal here is to identify brain areas in which learning-related plasticity occurs first and which among these areas predict subsequent learning.",[111],"Speech",[113,114],"Speech Motor Learning","Retention","2026-02-17",{"date":117,"type":118},"2026-02-19","ACTUAL",{"date":120,"type":118},"2024-10-01",{"date":122,"type":105},"2029-05-31",{"name":5,"class":6},1]
