Fig. 13.

Monkey 8 (laser vs enucleation). A single section through the upper layers from the cortex illustrated in Figure12A is shown. Dots mark the perimeter of the CO scotoma. Outside the scotoma, alternating light and dark rows of patches were visible everywhere, except in the monocular crescent (where they were rendered almost invisible by enucleation of the right eye) and in the blind spot representation (*). Inside the scotoma, all the patches appeared equally pale, indicating that enucleation and partial retinal damage have comparable effects on CO activity outside layer IV. Similar findings were present in the upper layers of the right visual cortex.
