Fig. 3. Maintained ipsilateral projections in the Vax2 mutants. Whole single eye injections with fluorescent cholera toxin B subunit label abundant contralateral (contra) and rare ipsilateral (ipsi) RGC projections in both Vax2^+/– (upper panels) and Vax2^–/– (lower panels) mice at P7. Arrowheads indicate ipsilateral termination sites of RGCs in successive rostral to caudal serial coronal sections, spaced at 200 µm, which traverse the thalamus into the SC. The ventral midline is indicated by the vertical lines.
