Abstract/Summary This chapter deals with projections from brain to spinal cord. 27 brain centers have been identified which send descending tracts to the spinal cord in mammals. The best known of these descending tracts is the corticospinal tract, which is a huge fiber bundle in humans and the other anthropoid primates. Apart from the corticospinal tract, which originates from a number of cortical areas, the most prominent descending tracts are those that arise from the red nucleus (rubrospinal), the vestibular nuclei (lateral and medial vestibulospinal), and the hindbrain reticular formation (lateral and medial reticulospinal). The other sites of origin of descending tracts, which are smaller in size, include the hypothalamus (paraventricular nucleus), prethalamus (zona incerta), pretectum (nucleus of Darkschewitsch), midbrain (superior colliculus, periaqueductal gray, supraoculomotor nucleus, interstitial nucleus of Cajal, and cuneiform nucleus), and rhombencephalon (parabigeminal nucleus, medial cerebellar nucleus, locus coeruleus, subcoeruleus nuclei, nucleus gigantocellularis, raphe, and the nucleus of the solitary tract). The origin and topography of supraspinal projections in humans is beginning to be elucidated using modern diffusion tensor imaging and tractography.
