FIGURE 9-40 Consequences of Lesions in Region V1 The shaded areas indicate regions of visual loss. (A) A complete lesion of V1 in the left hemisphere results in hemianopia affecting the right visual field. (B) A large lesion of the lower lip of the calcarine fissure produces quadrantanopia that affects most of the upper right visual quadrant. (C) A smaller lesion of the lower lip of the calcarine fissure results in a smaller scotoma.
