The angular gyrus lies near the superior edge of the temporal lobe, immediately posterior to the supramarginal gyrus. It is involved in the recognition of visual symbols. He also claims that the angular gyrus is not found in non-human species. Fibers of many different types travel through the angular gyrus, including axons associated with hearing, vision, and meaning. The arcuate fasciculus, the groups of fibers connecting Broca's area to Wernicke's area in the temporal lobe connects to this area.
