Figure 6.
Incertotectal termination in the squirrel SC. Chartings show the distribution of labeled cells (dots), axons (lines) and terminals (stipple) in the SC (D–J) following an injection of WGA-HRP into ZI (A–C). Most of the collicular labeling is found in the lower sublamina of the intermediate gray layer (SGI), but some is also present in the deep gray layer (SGP).
