Journal ArticleDOI
Improving Hand Function in Chronic Stroke
Wolf Muellbacher,Coletta Richards,Ulf Ziemann,George F. Wittenberg,Deborah Weltz,Babak Boroojerdi,Leonardo G. Cohen,Mark Hallett +7 more
TL;DR: Deafferentation, produced by a new technique of regional anesthesia of the upper arm during hand motor practice, dramatically improved hand motor function including some activities of daily living.
Journal ArticleDOI
Cortical reflex myoclonus
TL;DR: It is argued that this type of myoclonus is mediated in cerebral cortex and that the negative transient represents a paroxysmal depolarization shift (PDS) and may result from hyperactivity of a component of the long-latency stretch reflex.
Journal ArticleDOI
Increased iron in the dentate nucleus of patients with Friedreich's ataxia
TL;DR: A multigradient echo magnetic resonance sequence was developed for the three‐dimensional imaging of brain iron‐induced contrast and Relaxation rate (R2*) values in the unaffected globus pallidus were equal in FA patients and controls, although R2*values in the dentate nucleus of patients were significantly higher, which is most likely due to increased iron.
Journal ArticleDOI
Obstructive Sleep Apnea in Family Members
TL;DR: Two sons and their father had severe hypersomnolence and obstructive sleep apnea; a third son, although asymptomatic, was shown to have upper-airway obstruction during sleep.
Journal ArticleDOI
Disturbed surround inhibition in focal hand dystonia.
Young H. Sohn,Mark Hallett +1 more
TL;DR: The functional operation of surround inhibition in focal hand dystonia was tested and supported the idea that disturbed surround inhibition is a principal pathophysiological mechanism of dySTONia.
