Somatotopic Organization of the Primate Basal Ganglia

Witryna1 mar 2024 · The functional organization of the BG formulated in the 1980s was based on the concept that neuronal signals from the cortex flow to the striatum, through the Globus Pallidus and Substantia Nigra pars reticulata, and project back to the cortex via the thalamus, forming parallel cortico–basal ganglia–thalamo–cortical loops. Witryna13 lip 2024 · One of the most intensively studied functions of the basal ganglia is their role in controlling eye movements. Eye movement is influenced by an extensive network of brain regions that converge on a midbrain area called the superior colliculus (SC).

Witrynathe cerebellum, the basal ganglia receive no direct sensory input from the periphery. Secondly, a well developed somatotopic organization is maintained at all levels as information passes through the basal ganglia. Thirdly, most o thfe output from the basal ganglia is directed via the thalamus back to the cerebral cortex. WitrynaThe cortico-basal ganglia-thalamo-cortical loop (CBGTC loop) is a system of neural circuits in the brain.The loop involves connections between the cortex, the basal ganglia, the thalamus, and back to the cortex.It is of particular relevance to hyperkinetic and hypokinetic movement disorders, such as Parkinson's disease and Huntington's …
