Cortical plasticity and its implications for focal hand dystonia.
BACKGROUND The exact origin of focal dystonias has not been elucidated so far. Aberrant plasticity of the brain cortex is suspected to be a crucial factor in the development of this group of movement disorders. The aim of this article is to summarize recent findings on the etiopathogenesis of focal hand dystonias with a focus on the role of abnormal cortical plasticity. METHODS AND RESULTS A ...

group of movement disorders characterized by sustained involuntary muscle contractions that result from co-contracting antagonistic muscles and over ̄ow into extraneous muscles (Hallett, 1998). Like other types of focal dystonias, writer's cramp develops in the absence of known structural changes in the nervous system and it often requires extensive repetition of movements to emerge. The pathoph...
متن کاملEffect of Norepinephrine depletion on induction of experience dependent plasticity in male rat barrel cortex
Introduction: Barrel cortex of rats is a part of somatosensory cortex, which receives information from facial whiskers. Vibrisectomy by sensory deprivation leads to some changes in the barrel cortex, which have been known as experience dependent plasticity. On the other hand, Norepinephrine (NE) and locus coeruleus, which is the main source of NE, influenced response properties of cortical bar...
متن کاملL-NAME and 7-Nitroindazole Reduces Brain Injuries in Transient Focal Cerebral Ischemia in Rat
Background: The role of nitric oxide (NO) of endothelial or neuronal origins in cerebral ischemia and reperfusion injuries are far from being settled, extending from being important to not having any role at all. Objective: To investigate the role of NO of endothelial and neuronal origins in ischemia/reperfusion injuries in focal cerebral ischemia, L-NAME, a non selective NO synthase inhibitor...
متن کاملSensory Abnormalities in Focal Hand Dystonia and Non-Invasive Brain Stimulation
It has been proposed that synchronous and convergent afferent input arising from repetitive motor tasks may play an important role in driving the maladaptive cortical plasticity seen in focal hand dystonia (FHD). This hypothesis receives support from several sources. First, it has been reported that in subjects with FHD, paired associative stimulation produces an abnormal increase in corticospi...
