Document Summary
The autonomy of the occipital lobes: the occipital lobes form the posterior pole of the cerebral hemispheres, lying beneath the occipital bone at the back of the skull. On the medial surface of each hemisphere, the occipital lobe is distinguished from the parietal lobe by the parietal- occipital sulcus: within the visual cortex, however, are three clear landmarks. The most prominent is the calcarine sulcus, which contains much of the primary cortex. The calcarine sulcus divides the upper and lower halves of the visual world. On the ventral surface of each hemisphere are two gyri (lingual and fusiform). The lingual gyrus includes part of visual cortical regions v2 and vp, whereas v4 is in the fusiform gyrus. Subdivisions of the occipital cortex: the discovery that area v1 is functionally heterogeneous that a given cortical area may have more than one distinct function was unexpected.
