Which term refers to the bumps on the surface of the brain?

Explanation:
Bumps on the brain's surface are called gyri, the raised ridges that stand above the grooves between them. Sulci are those shallow grooves that separate gyri, while fissures are deeper grooves that divide larger regions. The cortex refers to the outer gray matter layer, not the bumps themselves. So the term for the bumps is gyri.
