SR Print(0) ID 1192997350 T1 Voluntary Movement: Motor Cortices T2 Principles of Neural Science, 6e YR 2021 FD 2021 PB McGraw Hill PP New York, NY SN 9781259642234 LK neurology.mhmedical.com/content.aspx?aid=1192997350 RD 2024/03/29 AB IN THIS CHAPTER, WE DESCRIBE HOW the cerebral cortex uses sensory information from the external world to guide motor actions that allow the individual to interact with the surrounding environment. We begin with a general description of what we mean by the term voluntary movement and some theoretical frameworks for understanding its control, followed by the basic anatomy of the cortical circuits involved in voluntary motor behavior. We then consider how information related to the body, external space, and behavioral goals is combined and processed in parietal cortical regions. This is followed by a discussion of the role of premotor cortical regions in selecting and planning motor actions. Finally, we examine the role played by the primary motor cortex in motor execution.
