[Autonomic corticofugal fibers].
Lesions affecting the neocortex have been carried out in 16 cats. Wallerian degeneration projects to the vegetative effector nuclei (nucleus of the vagus nerve and the nuclei intermedio-lateralis and intermedio-medialis of the spinal cord). The methods of silver impregnation used were those of Nauta, Fink-Heimer and Velayos-Ullán. Corticofugal fibers which show an intercalary formation, such as the nuclei reticularis parvocellularis, lateralis and dorsalis, and the nucleus of the solitary tract, are more numerous. There are also direct fibers for the intermediate zone (intermedio-lateralis and intermedio-medialis nuclei) of the thoracic and sacral spinal cord.
