The organization of regenerating axons in the Xenopus optic nerve

After regeneration of the optic nerve in Xenopus, with restoration of an orderly visuotectal map, HRP was applied to a small region of retina, or tectum, and the distribution of labelled fibres in the nerve investigated. As they passed the site of the crush, fibres became grossly disordered and remained so until they got to the chiasma.
