cuneus - BrainInfo

cuneus (CUN)

The term cuneus refers to the major convolution on the mesial aspect of the occipital lobe. Identified by dissection in the human it is separated from the parietal lobe rostrally by the parieto-occipital sulcus, from the lingual gyrus ventrally by the calcarine fissure. It is continuous with the superior occipital gyrus at the superior margin of the occipital lobe ( Duvernoy-1992; Ono-1990 ).. The boundaries in the macaque are similar except that it is separated from the occipital gyrus caudally by the superior calcarine fissure and from the isthmus of the cingulate gyrus rostrally by a boundary undefined by anatomical landmarks ( Martin-2000 ). It has no topological equivalent in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

Also known as: cuneus, Cuneus, Gyrus cuneus, cuneus of hemisphere, cuneus gyrus, cuneate lobule

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.
