E. Acetylated tubulin staining in 28 hpf controls (left) and mutants (right) showing severely affected outbranching of the trigeminal nerve (Vth cranial nerve). Notably, chd7-/- display reduced branching of the Vth cranial nerve (arrows) and axonal arborisation in the tectal area. Graphs showing quantitative analyses of percentage (n=5) and mean total length of peripheral projections (n=6) per zebrafish in controls and mutants (***p<0.001; **p<0.005, Student's t-test).
