Ascending and Descending Pathways of the Spinal Cord
There are a large number of ascending pathways, all of which have important direct projections to areas of the brain concerned with movement. In this chapter, a short summary of the types of sensory fibre which contribute to each tract, and the cells of origin of the tracts, will be given. The data is mostly from anatomical studies in the cat (and monkey); comparable human studies have not yet been performed.
