  • Each row represents one experimental animal. −, No growth cones; +, more than five growth cones; ++, very numerous growth cones; +++, fasciculated growth, single growth cones obscured; ND, not determined (when nerve segments were lost during staining procedure).

  • ↵F1-a Approximately 0–800 μm distal to the lesion site.

  • ↵F1-b Approximately 800–1600 μm distal to the lesion site.

  • ↵F1-c Entry zone of optic nerve into the diencephalon.
