Structure
The term cuneus comes from the Latin term for wedge, which reflects the shape of this occipital brain area. The cuneus is a wedge-shaped cortical area located in the medial occipital gyri, superior to the calcarine fissure and posterior to the parietal-occipital fissure. The cuneus is part of the occipital lobe, corresponding to Brodmann area 17. Pyramidal cells in the cuneus (striate cortex) project to extrastriatecortices (Brodmann areas 18 and 19). The cuneus consists of both striatal and extrastriatal visual cortex consisting of five layers. The striatal areas are largely posterior and are idiotypic homomodal (Mesulam’s classification), while the extrastriatal areas contain heterotypic cell types that respond to more complex visual information. The cuneus receives input from the contralateral superior retina corresponding to the lower visual field. From the extrastriatal areas of the cuneus, information is processed through both ventral and...
