Figure 9.
Pattern of collicular connections with ZI in the monkey. Chartings show the distribution of labeled cells (dots), axons (lines) and terminals (stipple) in the zona incerta (D–I) following an injection of WGA-HRP confined to the SC (A–C). Note the large numbers of cells in the lower half of ZI and numerous terminals in the upper half of ZI. This labeled band extended dorsolaterally, in islands of neuropil.
