• caudate nucleus
  • Reviews of magnetic resonance imaging (MRI) studies suggest that long-term treatment with amphetamine decreases abnormalities in brain structure and function found in subjects with ADHD, and improves function in several parts of the brain, such as the right caudate nucleus of the basal ganglia. (wikipedia.org)
  • dystonia
  • The causes of dystonia are not fully known, but it is currently thought that the condition results from a malfunction in a part of the brain called the basal ganglia. (netdoctor.co.uk)
  • rhythms
  • Our findings support a model of the basal ganglia-thalamocortical loop in PD in which gamma activity in primary motor cortex, modulated by the phase of low-frequency rhythms, drives STN unit discharge. (jneurosci.org)
  • signals
  • The motor cortices send signals through the basal ganglia to refine the choice of muscles that will participate in the movement and to amplify the activity in the motor cortices that will drive the muscle contractions. (wikipedia.org)
  • Cognition
  • In mammals, the basal ganglia are associated with motor control, cognition, emotions, learning, and domain-general functions important for executive functioning as well as support for domain-specific languages. (wikipedia.org)
  • movement
  • This structure is part of the basal ganglia, a part of the brain involved in the control of willed (voluntary) movement of the muscles. (thefreedictionary.com)
  • Effects of reversible blockade of basal ganglia on a voluntary arm movement. (semanticscholar.org)
  • 1. The effects of a reversible blockade of basal ganglia were examined in two monkeys trained to perform a visually guided, step-tracking arm movement around the elbow joint. (semanticscholar.org)
  • The direct pathway of movement is a neuronal circuit within the central nervous system (CNS) through the basal ganglia which facilitates the initiation and execution of voluntary movement. (wikipedia.org)
  • One of the two categories of movement disorders, hypokinesia is characterized by a partial or complete loss of muscle movement due to a disruption in the basal ganglia. (wikipedia.org)
  • The other category of movement disorder resulting from damage to the basal ganglia, hyperkinesia, features an exaggeration of unwanted motion, like twitching or writhing in Huntington's disease or Tourette syndrome. (wikipedia.org)
  • Hypokinetic symptoms arise from damage to the basal ganglia, which plays a role in producing force and computing the effort necessary to make a movement. (wikipedia.org)
  • regions
  • Granger causality (GC) at the phase-locking frequencies between synchronized electrodes revealed a unidirectional causality from right to left STN regardless of which side was moved.Phase synchronization across hemispheres between basal ganglia supports existence of a bilateral network having lateralized regions of specialization for motor processing.
