title: How axons grow down the Xenopus optic nerve.
abstract: Retinotectal fibres from different parts of the retina have been filled with Horse Radish Peroxidase (HRP). During their course down the nerve their ordering decays, but it is re-established at the chiasma, except for nasal fibres which remain relatively disordered. The consequences of this for development are discussed.
