What term refers to a furrow on the brain that is less deep than a fissure?

Explanation:
Understanding the grooves and ridges on the brain surface by how deep they are helps distinguish these features. A furrow that is shallower than a fissure is called a sulcus. Sulci are the shallow grooves that separate adjacent gyri, while a fissure denotes a deeper cleft that divides larger regions of the brain. The raised ridges between sulci are gyri, and the cortex refers to the entire outer gray matter that covers the brain, including its gyri and sulci. So the term for a furrow less deep than a fissure is sulcus.
