The effects of rTMS over the primary motor cortex: The link between action and language

► rTMS over the hand portion of M1 affects hand-action verb comprehension. ► RTs are slower for hand-action verbs after stimulation than in the baseline. ► Hand-action verbs are affected only after left M1 stimulation. ► Our results seem to indicate a functional role of M1 in action verbs comprehension.
