FIG. 9.
Course of the component of the spinoreticular tract that projects to the caudal reticular formation in a macaque monkey. The cells of origin are concentrated in the ventral horn in laminae VII and VIII. The axons decussate and ascend in the lateral funiculus and terminate in several nuclei of the reticular formation of the medulla and pons, including the nucleus gigantocellularis (NGc).
