title: [The optic nerve in the cat. II. Qualitative aspects of maturation in the adult cat].
abstract: 54 healthy cats were studied. In almost all cases, two types of degenerative signs could be seen: in the primary optic pathways, but also in the posterior funiculi and the spinal-cerebellar tracts, lesions of wide-diameter axons seen by their initial demyelination, accompanied by intense neuroglial reactions, and, on the other hand, a Wallerian degeneration of smaller axons situated in the axial part of the nerve. The percentage of these abnormalities must still be evaluated. Their eventual consequences and nature are discussed.
