The objective of this work was to determine if this gating phenomenon could persist beyond the period of repetitive movement. METHODS We recorded(More)
OBJECTIVE To determine if transient anaesthetic deafferentation of the radial nerve would lead to alterations in processing of early somatosensory evoked potentials (SEPs) from the median nerve or alter cortico-motor output to the median nerve innervated abductor pollicis brevis (APB) muscle. METHODS Spinal, brainstem, and cortical SEPs to median nerve(More)
