Journal ArticleDOI
The pathophysiology of primary dystonia.
Alfredo Berardelli,John C. Rothwell,Mark Hallett,Philip D. Thompson,M. Manfredi,C. D. Marsden +5 more
TL;DR: Evidence suggests that primary dystonia results from a functional disturbance of the basal ganglia, particularly in the striatal control of the globus pallidus (and substantia nigra pars reticulata) and abnormal regulation of brainstem and spinal cord inhibitory interneuronal mechanisms.
Journal ArticleDOI
Consensus Statement on the classification of tremors. from the task force on tremor of the International Parkinson and Movement Disorder Society
Kailash P. Bhatia,Peter G. Bain,Nin Bajaj,Rodger J. Elble,Mark Hallett,Elan D. Louis,Jan Raethjen,Maria Stamelou,Claudia M. Testa,Guenther Deuschl +9 more
TL;DR: Consensus criteria for classifying tremor disorders were published by the International Parkinson and Movement Disorder Society in 1998 but subsequent advances with regard to essential tremor, tremor associated with dystonia, and other monosymptomatic and indeterminate tremors make a significant revision necessary.
Journal ArticleDOI
Early consolidation in human primary motor cortex
Wolf Muellbacher,Ulf Ziemann,Ulf Ziemann,Joerg Wissel,Nguyet Dang,Markus Kofler,Stefano Facchini,Babak Boroojerdi,Werner Poewe,Mark Hallett +9 more
TL;DR: Low-frequency, repetitive transcranial magnetic stimulation of M1 but not other brain areas specifically disrupted the retention of the behavioural improvement, but did not affect basal motor behaviour, task performance, motor learning by subsequent practice, or recall of the newly acquired motor skill.
Journal ArticleDOI
Modulation of cortical motor output maps during development of implicit and explicit knowledge
TL;DR: Motor cortical mapping with transcranial magnetic stimulation revealed that the cortical output maps to the muscles involved in the task became progressively larger until explicit knowledge was achieved, after which they returned to their baseline topography.
Journal ArticleDOI
Modeling the current distribution during transcranial direct current stimulation.
TL;DR: Calculated values are comparable to those used in the most recent in vitro studies on modulation of neuronal activity and may be used to assess the current distribution during tDCS using new electrode montages, to help optimize montages that target a specific region of the brain or to preliminarily investigate compliance with safety guidelines.
