THE MOTOR CORTEX THE BASAL GANGLIA THE CEREBELLUM THE ACTIVATION SEQUENCE FOR THE MOTOR AREAS So many different structures in the brain are involved in motor functions that some people even say that practically the entire brain contributes to body movements. Though the motor cortex is usually associated with Areas 4 and 6, the control of voluntary movements actually involves almost all areas of the neocortex.
"A new model that says motor neurons send basic rhythmic patterns, not specific information, down the spine to drive movement. 'The brain has had an evolutionary goal to drive movements that help us survive. The primary motor cortex is key to these functions. The patterns of activity it displays presumably derive from evolutionarily older rhythmic motions such as swimming and walking. Rhythm is a basic building block of movement,' explained Churchland."
Luigi Rolando (1773-1831). Italian anatomist known for his pioneer research in brain localization of function. A range of neuroanatomical and neurological entities are named after him: the Rolandic vein, the Rolandic artery (central sulcal artery), the pre-Rolandic artery (precentral sulcal artery), the Rolandic operculum (post-central operculum), the Rolandic area (primary motor cortex), the substantia gelatinosa of Rolando, the fissure of Rolando (central sulcus) and Rolandic epilepsy.
Lateral view of the cerebral cortex showing the principal gyri and sulci. Major structures include the central sulcus and the precentral (primary motor), premotor, and postcentral (primary somatosensory) gyri. Also note the gyri situated rostral to the premotor cortex, including the orbital gyri, which mediate higher order intellectual functions and contribute to the regulation of emotional behavior. Brocas motor speech area and Wernickes area (for reception of speech) are important areas…
