Which term is a brain groove that is shallower than a fissure?

Explanation:
Shallow grooves on the brain surface are called sulci, which are shallower than fissures. The brain’s surface features ridges called gyri and grooves called sulci; fissures are the deeper grooves that separate major brain regions. So when asked for a groove that is shallower than a fissure, the correct term is sulcus. The cortex is the outer layer of neural tissue and is not a groove.
