The answer is the fourth one: gyrus.

Explanation for each option:

  • Fissure: This is a deep groove in the brain, not an elevated ridge. It separates large regions of the brain.
  • Sulcus: This is a shallow groove on the surface of the brain, not an elevated ridge. It separates gyri.
  • Furrow: This term is not typically used in neuroanatomy to describe structures in the brain.
  • Gyrus: This is an elevated ridge of the cortex. Gyri are the raised portions between the sulci.

Summary: An elevated ridge of the cortex is called a gyrus.
