Figure 5.

Dendritic arborization fields of labeled neurons. Ratios of dendritic arborization fields (as shown by the polygon in Fig. 4 J) to the areas of the tectal hemisphere (as outlined by the thin line in Fig. 4 J) are plotted for the labeled neurons at 7 dpf (n = 87). The means (±SE, SEM) are shown by the horizontal bars for the total tectal neurons (black) and the four different groups (very large, 14.56 ± 1.37%, red; large, 9.17 ± 0.16%, orange; middle, 6.88 ± 0.08%, green; small, 4.10 ± 1.18%, blue).
