Abstract

In this chapter we summarize the current knowledge concerning the anatomical, physiological, and neurochemical substrates that underlie both physiological and pathological pain. We describe the transmission of inputs from the periphery to the CNS, the physiological properties of the neurons activated by painful stimuli, and the neurochemicals that have been found to mediate or modulate synaptic transmission in somatosensory pathways. We break down our review into separate sections on the peripheral nervous system and the CNS, with a further breakdown of the CNS into the spinal cord dorsal horn and the brain and brainstem. We end each of these sections with a specific discussion of the pathology in these systems in chronic pain. In the last section of the chapter we discuss pain control, with particular emphasis on brainstem and brain mechanisms.
