superior calcarine sulcus (clss)

The term superior calcarine sulcus (clss) refers to one of two extensions of the calcarine fissure (clf) where it splits into two short vertically oriented branches near the occipital pole (ocp). This is the dorsally curved superior branch; the other is a symmetrical, ventrally curved inferior calcarine sulcus (clsi). Both are found in the macaque ( Martin-2000; Paxinos-2009a ) and, though not named as separate sulci, illustrated in human brain atlases ( Ono-1990; Duvernoy-1992; Mai-1997 ). No comparable structures are found in the smooth cerebral cortex (CTX) of the rat or mouse ( NeuroNames ). Updated 30 Oct 2024.

Also known as: Ramus ascendens fissurae calcarinae, superior ramus of calcarine fissure, upper calcarine sulcus, superior calcarine sulcus, retrocalcarine sulcus

Models Where It Appears
Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
