Optic Nerve Appearance

The upper and lower visual fields are also topographically mapped onto the lateral geniculate body and visual cortex. The upper field is represented in the lateral parts of the lateral geniculate nuclei and the inferior portions of the visual cortex, and the lower visual field is represented in the corresponding medial and superior regions. The macula (central visual field) is represented in the central parts of the lateral geniculate nuclei and the posterior visual cortex, and in the peripheral retina, in the peripheral parts of the lateral geniculate nuclei, and the anterior visual cortex. The fovea, the central spot of the macula, is represented by a proportionally larger cortical area than the periphery of the retina.
