Document Summary
Chapter 7. 8 - subcortical structures: the basal ganglia. Basal ganglia = two groups of cerebral nuclei, one in each hemisphere. Play a role in the control of movement. In general, located lateral and slightly anterior to the thalamus. The amgydala is considered to e a structure of both the limbic system and the basal ganglia motor sustem. The importance of the bg in the control of movement is apparent in people with. Characterized by the deterioration of dopaminergic neurons that project from the substantia nigra of the midbrain to the striatum.
