Different descending pathways mediate early and late portions of lower limb responses to transcranial magnetic stimulation

This is the authors' abstract. We don't add key points for this paper.

Early and late portions of the response to transcranial magnetic stimulation (TMS) in a lower limb postural muscle are modulated independently by cortical suppression, late motor evoked potentials (MEPs) being facilitated during cortical inhibition. These results suggest a cortico-brain stem transmission pathway for late portions of the TMS-induced MEP.
