Goal-directed movements are associated with unique neurophysiological alterations in motor-related brain regions. This study systematically examined the interhemispheric connectivity between the premotor (dorsal, PMd; ventral, PMv) and the primary motor (M1) cortices using dual-site transcranial magnetic stimulation. We had 30 right-handed young adults (15F; 26.5±4.3yrs) participate in three experimental conditions to examine interhemispheric inhibition (IHI) between: (1) PMd to M1, (2) PMv to M1 and (3) M1 to M1. PMd and PMv were located relative to M1 (PMd: 2cm anterior, 1cm medial; PMv: 3cm
