Summary of experimental results.

ANOVA results have been categorized with respect to whether data was compared between brain regions (i.e. primary motor cortex (M1) and dorsal premotor cortex (PMC)) or interventions (i.e. cathodal and sham stimulation) and whether they examine functional performance or electrophysiological properties. The test of MEP latency contains the two-level factor muscle for forearm and hand muscles. The two-level factor time distinguishes between early(40 min) period aftereffects. The four-level factor TMS intensity refers to 10% increments of the individual resting motor threshold (RMT) used as stimulation intensities to assess input-output curves. Paired-pulse stimulation sequences contain the two-level factor ISI reflecting SICI and ICF protocols. Please refer to the methods section for further details. * p
