LAB 8: CONTROL OF MOVEMENT - BASAL GANGLIA, CEREBELLUM

Student Preparation Guide

Objectives

  • Identify the basal ganglia and associated tracts in the brain specimens and micrographs.
  • Describe the net effect of the direct and indirect pathways on the chronic inhibition of the thalamus.
  • Describe how motor, association and limbic areas of the cortex interact with the basal ganglia.
  • Explain the consequence of lesions to the basal ganglia.
  • Identify the three different functional areas of the cerebellum (vestibulocerebellum, spinocerebellum, cerebrocerebellum) and correlate these with the surface landmarks of the cerebellum.
  • Describe how the three functional areas of the cerebellum influence CNS function, in particular the control of movement.
  • Describe the major tracts travelling in the cerebellar peduncles.
  • Explain the consequence of lesions to the cerebellum.
  • Describe the blood supply to the cerebellum and the basal ganglia.
  • Explain in broad terms how cortical regions, major descending tracts, the basal ganglia and the cerebellum together control movement.
