Monkey 8 (laser vs enucleation).A, Autoradiograph of the left lateral geniculate body, showing a gap in laminae 2 and 3 from retinal ganglion cell destruction (large arrow). The gap has fuzzy edges and contains fragments of label (small arrows). B, Another section, 300 μm more caudal, showing migration of the gap dorsally into laminae 3 and 5 (large arrows). Again, the label is fragmented (small arrows). To map this complex scotoma precisely in three dimensions would be a daunting task, requiring dozens of electrode penetrations and arbitrary decisions about boundaries.
