The word “cuneus” refers to a specific anatomical structure in the brain. In English, it is often used to denote a wedge-shaped area of the brain located in the occipital lobe, which is involved in visual processing. The cuneus is situated above the calcarine sulcus and is implicated in the perception of visual stimuli. Additionally, “cuneus” can be used in a more general sense to describe anything that is wedge-shaped.
