(van Gehuchten.) ruination of the tract is unknown. The tectospinal tract, located in the ventralfuniculus, is composed of fibers which take origin in the roof (tectum) of themesencephalon, cross the median plane and descend into the anterior funiculusof the spinal cord, and end in the gray matter of the anterior column. The tractis concerned chiefly with optic reflexes. The vestibulospinal tract, also locatedin the anterior funiculus, arises from the lateral nucleus of the vestibular nerve 112 THE NERVOUS SYSTEM in the medulla oblongata and conveys impulses concerned in the maintenanceof equilibrium. Some of its fibers can be traced as far as the lower lumbarsegments. They end in the gray matter of the anterior column. Hemisection of
