Thus there is established a strict physiological association, per-mitting the action of a dextrorotary system, turning the eyes toward the right, or alevorotary system, turning the eyes to the left, an association which can be incitedand activated may be by the cortex, or by various sensory or sensorial paths, labyrinthine,tactile or optic. 1. The cortical oculorotary pathway (colored dark red in the right, pale red onthe left) belongs to the corticonuclear path (CoN) (see Plats I, 0) and takes its(204) PLATE VlIT Pulvinar

It passes by way of theknee of the internal capsule, internal portion of the cerebral peduncles; descends with theaberrant fibers of the pyramidal tracts (see Plate I, D) in the median lemniscus and passesto the nuclei of the III pair, to the nuclei of the VI pair of the opposite sides, and to thecephalorotary nuclei of the two sides. 2. The labyrinthine oculorotary pathway, colored yellow, contains a vestibularoculorotary path, for static equilibrium, and a cochlear, or acoustic, oculorotary pathway.The vestibular oculorotary pathway takes its origin in the cells of the terminal nuclei ofthe vestibular root (NBe, NVIIIv,ND). Its fibers belong to the posterior and interiorarcuate fibers of the meduUopontine tegmentum (Jap). They actionate the two VInuclei and give to the posterior longitudinal fasci
