Journal ArticleDOI
In vitro evaluation of a 4-leaf coil design for magnetic stimulation of peripheral nerve.
Bradley J. Roth,Paul J. Maccabee,L. Eberle,V.E. Amassian,Mark Hallett,John Cadwell,G.D. Anselmi,G. T. Tatarian +7 more
TL;DR: The performance of a 4-leaf magnetic coil was evaluated during magnetic stimulation of a peripheral nerve in vitro and a hyperpolarizing magnetic stimulus failed to slow or block a propagating action potential.
Journal ArticleDOI
The role of sensory information in the pathophysiology of focal dystonias
Antonella Conte,Giovanni Defazio,Giovanni Defazio,Mark Hallett,Giovanni Fabbrini,Alfredo Berardelli +5 more
TL;DR: It is concluded that it is crucial to study sensory as well as motor pathophysiology to fully understand focal dystonias, and the link between sensory system abnormalities and dystonic motor activity in the context of the 'network model' of dystonia is explored.
Journal ArticleDOI
Gait disturbance associated with white matter changes: A gait analysis and blood flow study
Kazumi Iseki,Takashi Hanakawa,Kazuo Hashikawa,Hidekazu Tomimoto,Manabu Nankaku,Hiroshi Yamauchi,Mark Hallett,Hidenao Fukuyama +7 more
TL;DR: The present study suggests that abnormalities in the basal ganglia-thalamo-cortical loops partly explain gait disturbance observed in a subset of subjects with ARWMC.
Journal ArticleDOI
Neurophysiological study of subacute combined degeneration
Edward J. Fine,Mark Hallett +1 more
TL;DR: Three patients with subacute combined degeneration of the spinal cord due to vitamin B12 deficiency showed a characteristic pattern of abnormalities on neurophysiological tests which corresponded to the clinical signs and symptoms, shedding light on the pathology of this disorder.
Journal ArticleDOI
Noninvasive mapping of human motor cortex
Leonardo G. Cohen,Mark Hallett +1 more
TL;DR: Human motor cortex was stimulated using brief, high-voltage electrical stimulation using a bipolar surface stimulator with anode placed at multiple positions on the scalp and the cathode situated 2.5 cm anterior to the anode.
