The anatomy of the nervous system, from the standpoint of development and function . Axiscyli ndcf B Fig. 127.—Diagram to illustrate the principle of neurobiotaxis.

(Kappers.) pers believes that it is a galvanotropic phenomenon, on the basis of the fact that the stimu-lation center is electrically negative, i. e., a cathode with reference to the surrounding tissue. Numerous instances might be cited of the action of this taxis, but two will suffice. Ithas already been noted that the eye-muscle nuclei receive most of their collaterals from theoptic and vestibular reflex tracts; and these appear to be the most important factors in thedetermination of the positions occupied by those nuclei. The changes in position of th
