T/F The basal nuclei are a component of the brainstem
F. The basal nuclei are masses of subcortical gray matter that are in a feedback circuit with the cerebrum for the functions of highly practiced movements, starting and stopping movements, walking, and dyskinesias.
T/F The cerebellum regulates balance and posture
F. The reticular activating system regulates balance and posture. (as well as sleep and conscious attention)
