Which brain surface feature is a raised area called a gyrus?

Explanation:
On the brain’s surface, raised ridges are called gyri. The grooves between them are sulci, and deep grooves are fissures. The cortex refers to the outer layer of neural tissue, not a specific surface feature. So the raised, rounded feature described is a gyrus because that is exactly the term for a cortical ridge.
