Changing views of basal ganglia circuits and circuit disorders

Abstract

The basal ganglia (BG) have long been considered to play an important role in the control of movement and the pathophysiology of movement disorders, such as Parkinson's disease (PD). Studies over the past decades have considerably broadened this view, indicating that the BG participate in multiple, parallel, largely segregated, cortico-subcortical reentrant pathways involving motor, associative and limbic functions. Research has shown that dysfunction within individual circuits is associated not only with movement disorders, but also with neuropsychiatric disorders. Accordingly, a number of movement disorders and neuropsychiatric disorders such as obsessive compulsive disorder and Tourette's syndrome are viewed as "circuit disorders." We here discuss the changes in our current understanding of the anatomic and functional organization of BG circuits and related circuit disorders.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Accumulating evidence suggests neuroplasticity within the corticostriatal circuit is impaired under conditions of dopamine denervation.

    “However, accumulating evidence suggest that neuroplasticity within this corticostriatal circuit is also impaired under conditions of DA denervation 41–44”
  • Exercise can alter the storage and release of glutamate in presynaptic terminals that may improve circuit function and diminish the increased inhibitory drive of the dopamine depleted striatum.

    “In addition to its receptors, exercise can also alter the storage and release of glutamate in presynaptic terminals that may also improve circuit function and diminish the increased inhibitory drive of the DA depleted striatum 41–44.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
