The meaning of SULCUS is furrow, groove; especially : a shallow furrow on the surface of the brain separating adjacent convolutions.

The grooves or depressions found on the outer layer of the brain, known as the cerebral cortex, are called cerebral sulci. The cerebral cortex consists of gray matter and encompasses the white matter …

The sulci and fissures are shallow and deep grooves respectively in the cortex, that organise the brain into its regions. A sulcus is a shallow groove that surrounds a gyrus or part of a gyrus.

Sulci, the plural form of sulcus, are grooves or furrows that form indentations on the surface of the cerebral cortex. These depressions separate the gyri, the elevated ridges of the brain.
