Movement related desynchronisation pattern preceding voluntary movement in untreated Parkinson's disease.
OBJECTIVE To study planning of movement in Parkinson's disease. METHODS The spatiotemporal pattern of movement related desynchronisation (MRD) preceding a self paced voluntary wrist flexion was compared between two groups of 10 untreated right and left hemiparkinsonian patients receiving no treatment and 10 control subjects. The MRD was computed in the 9 to 11 Hz frequency band from 11 source...
متن کاملSaccadic eye movement related potentials.
The saccadic eye movement related potentials (SEMRPs) enable to study brain mechanisms of the sensorimotor integration. SEMRPs provide insight into various cognitive mechanisms related to planning, programming, generation and execution of the saccadic eye movements. SEMRPs can be used to investigate pathophysiological mechanisms of several disorders of the central nervous system. Here we shortl...
متن کاملMovement-related cortical activation with voluntary pinch task: simultaneous monitoring of near-infrared spectroscopy signals and movement-related cortical potentials.
This study was designed to evaluate hemodynamic and electrophysiological motor cortex responses to voluntary finger pinching in humans, with simultaneous recording of near-infrared spectroscopy (NIRS) signals and movement-related cortical potentials (MRCP). Six healthy, right-handed subjects performed 100 trials of voluntary right-thumb index-finger pinching with about a 10-second interval at t...
متن کاملEvaluation of event-related desynchronization (ERD) preceding and following voluntary self-paced movement.
A method of accurate storage and on-line preprocessing of an EEG signal, preceding and following a trigger signal, elicited by button pressing, is described. The method was used to study the changes occurring in the power of the rhythmic activity within the alpha band in central areas, during voluntary, self-paced movement in 10 normal humans. A short-lasting decrease or phasic event-related de...
متن کاملAlterations in voluntary movement execution in Huntington's disease are related to the dominant motor system: evidence from event-related potentials.
Huntington's disease is an autosomal dominant neurogenetic disorder leading to striatal atrophy, characterized by involuntary movements. Voluntary movements also deteriorate, but the neurophysiological mechanisms are less understood. We investigated voluntary movement execution and its neural correlates by means of movement-related potentials (MRPs) in symptomatic HD (HD), presymptomatic HD (pH...
