Fig. 7. Tectal neuropil boundaries dissolve in fuzz wuzzy (fuzz),
beyond borders (beyo) and breaking up
(brek) mutants. (A-D) Z-projections of confocal image stacks
showing lateral views of tecta in 6 dpf live Brn3c:mGFP larvae. The
boundary of the tectum is smooth and well defined in wild type (A). In
fuzz (B), axon arbors are less dense in the tectal neuropil and often
overshoot the tectal boundary (arrowheads). The overshooting phenotype is more
severe in beyo (C) and brek (D). Asterisks indicate
melanophores. Scale bars: 20 µm.
