[Functional role of several groups of neurons in oculomotor nerve nuclei (experimental study)].

The localization and functional significance of some groups of neurons in the main nuclei of the cat aculomotor nerve were studied with the aid of the method of retrograde degeneration. The topography of the oculomotor nerve nuclei in some representatives of the order of rodents, hare-like and predatory animals was specified. The conducted study demonstrated that the cell groups in the main nuclei of the oculomotor nerve were situated rostro-caudally in the following order: for the superior straight, internal straight and inferior straight muscles. In the middle and caudal sections of the nuclei there is a semidecussation.
