FIGURE 4 The olfactory and optic nerves. (a and b) 3D depth coding views of a whole mount antibody staining (acetylated alpha-tubulin)
of a NF stage 47/48 X. laevis tadpole. (a) dorsal view of the anterior head region. (a1) maximum intensity projection of the same digital
stack. Dorsal view of the olfactory nerve (I). (b) dorsal view of the anterior head region around the eye. (b1) maximum intensity projection
of the same digital stack. Dorsal view of the optic nerve (II). (b2) 3D projection of the same digital stack. Lateral view of the eye to show
the convergence of the optic fibers toward the optic papilla. (b3) histological section through the diencephalic region of a X. laevis tadpole
at NF stage 46. The Chiasma opticum is closely associated with the ventral region of the diencephalon. Black and white scale bars are
