Document Summary

Q9: discuss the role of following brain regions in movement planning and control: The premotor cortex lies just in front of (anterior to) the primary motor cortex. It is involved in the sensory guidance of movement, and controls the more proximal muscles and trunk muscles of the body. In our example, the premotor cortex would help to orient the body before reaching for the glass of water. Specifically, the lateral dorsal premotor area is responsible for sensorimotor transformations, such as how a person converts visual information into an actual movement, whereas the lateral ventral premotor area is specific to grasping and working with the hands. It has been found that more activity occurs in the premotor cortex while learning new actions (unlearned movements) and in external movements. For this reason, this area of the brain is heavily utilized during sport, where external cues guide the movement of an individual.
