The term area V3 refers to a cortical structure defined by multiple criteria in the human and the macaque. It occupies a belt around the occipital lobe located largely between area V2 and area V4. A part of early visual cortex, it is distinguished from surrounding areas by myelination, thickness, visuotopic connectivity, and resting functional connectivity with area V1. Other authors have referred to the same topological area as V3d, V3v, VP, hOC3d, or hOC3v ( Glasser-2016 ).
