Figure 3. Elongation of ventrotemporal retinal targets in superior colliculus.
A. The collicular target zone from axons originating from ventrotemporal retinal (sectors 15–18 in Figure 1D) shows a characteristic elongation along the rostrocaudal axis. B. Target zones originating from neighboring ventronasal retina (sectors 13–14 in Figure 1D) are much less elongated. C. Target zones from axons originating from dorsal retina (sectors 1–3) are also much less elongated than those from ventrotemporal retina. D. Quantification of the target zone elongation along the rostrocaudal relative to mediolateral dimension due to injections in ventrotemporal (n=6; black bar), ventronasal (n=8; grey bar) and dorsal (n=7; white bar) retina. Medial is to the right, caudal is up. 500 μm scale bar in C applies to all panels.
