Presence and absence of muscle contraction elicited by peripheral nerve electrical stimulation differentially modulate primary motor cortex excitability
R Sasaki, S Kotan, M Nakagawa… - Frontiers in Human …, 2017 - frontiersin.org
Modulation of cortical excitability by sensory inputs is a critical component of sensorimotor
integration. Sensory afferents, including muscle and joint afferents, to somatosensory cortex
(S1) modulate primary motor cortex (M1) excitability, but the effects of muscle and joint
afferents specifically activated by muscle contraction are unknown. We compared motor
evoked potentials (MEPs) following median nerve stimulation (MNS) above and below the
contraction threshold based on the persistence of M-waves. Peripheral nerve electrical …
