Movement-related potentials in Parkinson's disease. Motor imagery and movement preparation.
Movement-related potentials (MRPs) associated with voluntary movements reflect cortical activity associated with processes of movement preparation and movement execution. Early-stage pre-movement activity is reduced in amplitude in Parkinson's disease. However, it is unclear whether this neurophysiological deficit relates to preparatory or execution-related activity, since previous studies have...
متن کاملMovement preparation in Parkinson's disease. Time course and distribution of movement-related potentials in a movement precueing task.
Investigations of the effects of advance information on movement preparation in Parkinson's disease using reaction time (RT) measures have yielded contradictory results. In order to obtain direct information regarding the time course of movement preparation, we combined RT measurements in a movement precueing task with multi-channel recordings of movement-related potentials in the present study...
متن کاملMovement-related cortical evoked potentials using four-limb imagery.
We compared the electroencephalographic changes during actual and imaginary movements with four limbs and classified optimally the responses during four-limb imagery. Evoked potentials in imagery exhibited lower and delayed peaks compared to actual-movement responses, but activations in the primary and the supplementary motor area were similar. Source-modeling analysis revealed that the motor a...
متن کاملPreparation to respond as manifested by movement-related brain potentials.
Ten subjects were instructed to squeeze a dynamometer in a prescribed manner in order to assess the effects of motor preparation on event-preceding brain potentials. Right and left hand responses were required in 5 different experimental conditions allowing different degrees of advance preparation. Six channels of EEG (F3, F4, C3', C4', P3, P4) and two channels of EMG were digitized over a 3000...
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...
