thalamus

Structure that functions as the major sensory relay center, receives afferent information from entire body and CNS, information converges, and is distributed to cortex and other parts of the body

limbic system

Structure that regulates emotion, motivation for survival, learning, and memory. Consists of 3 structures: cingulate gyrus, amygdala, and hippocampus

basal ganglia

Subcortical structure that is a collection of nuclei including: caudate nucleus, putamen, globus pallidus, substantia nigra. Functions in regulating motor functions and muscle tone and integrates motor activity. This structure receives afferent information and sends efferent information to other parts of body and CNS, has some cognitive functions as well.

basal ganglia lesions

Lesions in this subcortical structure cause a loss of inhibitory control of patterned motor behaviors - Parkinson’s and Huntington’s disease

cerebellum

Structure of brain that consists of structures: 2 cerebellar hemispheres, gyri, sulc, white and gray matter, and 3 cerebellar peduncles. Functions in coordinating muscle movements, regulates muscle tone, and BALANCE. Makes adjustments in movements based on sensory input, does NOT initiate movement, plays a role in motor learning and cognition

cerebellar peduncles


3 structures in the cerebellum (superior, middle, inferior) that receive/send information from/to the spinal cord, brainstem, basal ganglia, thalamus, and cortex

cerebellar dysfunction

Dysfunction in which paresis (weakness of voluntary movement), intention tremor, disequilibrium, ataxia, and dysarthria
