The document discusses several topics related to brain mechanisms of movement: 1) The primary motor cortex and areas near it such as the premotor cortex and supplementary motor cortex are involved in controlling movement, with the primary motor cortex sending axons to the basal ganglia and brainstem/spinal cord. 2) The cerebellum plays an important role in motor control and learned motor behaviors through connections with other parts of the brain and spinal cord. 3) Basal ganglia structures like the caudate nucleus, putamen, and globus pallidus are important for habit learning and movement selection, and disorders like Parkinson's and Huntington's disease impact these areas.
