  • peripheral ganglia
  • Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain. (wikipedia.org)
  • signals
  • The "behavior switching" that takes place within the basal ganglia is influenced by signals from many parts of the brain, including the prefrontal cortex, which plays a key role in executive functions. (wikipedia.org)
  • spinal cord
  • Apart from the spinal cord, there are also peripheral nerves of the PNS that synapse through intermediaries or ganglia directly on the CNS. (wikipedia.org)
  • olfactory
  • Many consider the retina and the optic nerve (2nd cranial nerve), as well as the olfactory nerves (1st) and olfactory epithelium as parts of the CNS, synapsing directly on brain tissue without intermediate ganglia. (wikipedia.org)
  • Tourette
  • Though motor disorders are the most common associated with the basal ganglia, recent research shows that basal ganglia disorders can lead to other dysfunctions such as obsessive compulsive disorder (OCD) and Tourette syndrome. (wikipedia.org)
  • involvement
  • One possible factor could be the natural accumulation of iron in the basal ganglia, causing neurodegeneration due to its involvement in toxic free-radical reactions. (wikipedia.org)
  • anatomy
  • We found systematic variations in input along both the medial-lateral and anterior-posterior neuraxes in close agreement with canonical features of basal ganglia anatomy in the rat. (frontiersin.org)
  • lateral
  • Mri found bilaterally along the inferior lateral aspect of the basal ganglion, either old lacunar infarctions or bilateral benign cysts. (healthtap.com)
  • During development, the cells that migrate tangentially to form the basal ganglia are directed by the lateral and medial ganglionic eminences. (wikipedia.org)
  • brain
  • Most of my recent work has focused on the basal ganglia, an area deep in the brain that is dysfunctional in Parkinson's disease, Huntington's chorea, and schizophrenia. (millersville.edu)
  • The basal ganglia are a part of the brain. (healthtap.com)
  • Like most parts of the brain, the basal ganglia consist of left and right sides that are virtual mirror images of each other. (wikipedia.org)
  • the current work is in broad agreement with a general trend in neuroscience of volition: although we may experience that our conscious decisions and thoughts cause our actions, these experiences are in fact based on readouts of brain activity in a network of brain areas that control voluntary action. (wikipedia.org)
  • posterior
  • 7mm ovoid lesion fluid density shown within posterior inferior aspect of right basal ganglia small vessel coursing through it incidental virchow robin? (healthtap.com)
  • diseases
  • Also, several major degenerative diseases of the basal ganglia, including Parkinson's disease and Huntington's disease, are specific to humans, although "models" of them have been proposed for other species. (wikipedia.org)
