Abstract

Sensory processing in the spinal cord involves interactions among primary afferent fibers bearing information from sensory receptors, interneurons, ascending-tract cells conveying sensory messages to the brain, and descending-tract cells that modulate spinal cord circuits. Such interactions are complex and still poorly understood. In this chapter, the interactions between primary afferent fibers and spinal interneurons will be discussed, as well as the interactions between descending tracts and interneurons. The organization of the ascending tracts and their descending control form the subject matter of Chapters 6–9.
