What does the term gyrus mean in brain anatomy?

Explanation:
In brain anatomy, a gyrus is a ridge or raised area on the cerebral cortex. The cortex folds into gyri and sulci, with sulci being the grooves or valleys between the ridges. This folding increases the surface area, letting more neurons fit in. So the term describes a raised convolution, not a valley or groove. Among the options, the best match is ridge. Hill isn’t a technical term in neuroanatomy, and valley or groove describe sulci, not gyri.
