In this video, I discuss the motor cortex. I describe the location and functions of the primary motor cortex and the nonprimary motor cortex, which is often divided into the supplementary motor cortex and premotor cortex. I also describe the main pathways by which motor information travels away from the motor cortex: the corticospinal tract, which carries motor information to the spinal cord to cause movement of the body, and the corticobulbar tract, which carries motor information to the brainstem to cause movement of the head, neck, and face.
Welcome to Neuroscientifically Challenged! All of the content for the site is collected on this home page, but if you're looking for specific types of content you can use the menu bar above. By clicking on Articles, you'll find links to blog articles on a variety of different neuroscience topics. The Know Your Brain link will take you to a listing of reference articles, each of which deals with a different part of the nervous system. Clicking on the 2-Minute Neuroscience Videos link will take you to an assortment of 2-minute videos that each teach you about a different aspect of neuroscience. And the Glossary contains a large selection of definitions for common neuroscience terms.
