REGENERATION OF POSTERIOR ROOT FIBERS IN THE CAT

REGENERATION OF POSTERIOR ROOT FIBERS IN THE CAT Abstract Regeneration of sectioned posterior root fibers may be discussed from two points of view: regeneration in a proximal direction from the dorsal root ganglion and regeneration in a distal direction from possible cells of origin in the spinal cord. The question of regeneration in a distal direction from cells of origin in the spinal cord is intimately related to the problem of the existence of efferent fibers in the posterior root. This question has been thoroughly reviewed by Sherrington1 and more recently by Hinsie;2 it would be superfluous to discuss the subject here. While it is generally agreed that there are efferent fibers in the posterior roots of certain lower forms, such as Amphioxus, Petromyzon, Pristiurus, Myxine and amphibians, birds and reptiles, the presence of such fibers in the posterior roots of mammals is still the subject of controversy, with an imposing array of workers on either side.

Abstract

Abstract Regeneration of sectioned posterior root fibers may be discussed from two points of view: regeneration in a proximal direction from the dorsal root ganglion and regeneration in a distal direction from possible cells of origin in the spinal cord. The question of regeneration in a distal direction from cells of origin in the spinal cord is intimately related to the problem of the existence of efferent fibers in the posterior root. This question has been thoroughly reviewed by Sherrington1 and more recently by Hinsie;2 it would be superfluous to discuss the subject here. While it is generally agreed that there are efferent fibers in the posterior roots of certain lower forms, such as Amphioxus, Petromyzon, Pristiurus, Myxine and amphibians, birds and reptiles, the presence of such fibers in the posterior roots of mammals is still the subject of controversy, with an imposing array of workers on either side.
