Increased SAI during grasp execution indicates distinct M1 circuits engaged in different grips.
Corticospinal excitability for precision grip is enhanced with AP stimulation, showing grip-specific effects.
Transcranial magnetic stimulation applied in different orientations elucidates M1's role in grasp modulation.
Findings suggest that the premotor cortex is key in motor planning and transforming visual properties into movements.
