The structure of the optic nerve of Hydromantes genei, was investigated by confocal laser scanning microscopy and by the Cajal-De Castro method. This nerve appears to be composed of unmyelinated fibres, which is a rare case in amphibians. In view of this and the fact that it contains a relatively small number of nervous fibres, the optic nerve of N. genei, in comparison with other species of Plethodontidae, can be considered a structure with a low level of complication.

Abstract
The structure of the optic nerve of Hydromantes genei, was investigated by confocal laser scanning microscopy and by the Cajal-De Castro method. This nerve appears to be composed of unmyelinated fibres, which is a rare case in amphibians. In view of this and the fact that it contains a relatively small number of nervous fibres, the optic nerve of N. genei, in comparison with other species of Plethodontidae, can be considered a structure with a low level of complication.
