occipital lobe
the most posterior (rearward) subdivision of each cerebral hemisphere, roughly shaped like a pyramid and lying under the skull’s occipital bone. It contains several visual areas that receive and process visual stimuli, and it is involved in basic visual functions (e.g., visual acuity; contrast sensitivity; perception of color, form, and motion) as well as higher level ones (e.g., figure-ground segregation based on textural cues). A region of it, the occipital face area (OFA), has been identified as crucial to face recognition. See also fusiform gyrus.
