Detailed explanation-1: -The surface of the cerebrum is imprinted with numerous ridges or convolutions called gyri. These gyri are separated by grooves; the shallow ones are called sulci and very deep ones are called fissures. The sulci serve as boundaries for the lobes of the cerebrum, the frontal, parietal, occipital, and temporal lobes.

Detailed explanation-2: -In neuroanatomy, a sulcus (Latin: “furrow", pl. sulci) is a depression or groove in the cerebral cortex. It surrounds a gyrus (pl. gyri), creating the characteristic folded appearance of the brain in humans and other mammals.
