The calcarine sulcus, also known as the calcarine fissure, is a deep sulcus of the brain, located on the medial surface of the occipital lobe. The term "calcarine" comes from the Latin word "calcar", which means spur.

It travels horizontally from the occipital lobe to meet the parieto-occipital sulcus just posterior to the venous junction of the great cerebral vein and the straight sinus.

The calcarine sulcus houses the primary visual cortex (Brodmann area 17). It is in this sulcus that visual stimuli from the optic tract end up.

Located deep within the calcarine sulcus is the calcarine artery, a branch of the posterior cerebral artery, supplying the surrounding region.

Terminology	English: Calcarine sulcus Synonyms: Calcarine fissure Latin: Sulcus calcarinus Synonyms: Fissura calcarinus
Definition	The calcarine sulcus is located on the medial surface of the occipital lobe and houses the primary visual cortex.
