<jats:sec><jats:label /><jats:p>Nociceptive input is relayed from polymodal nociceptors (Latin <jats:italic>nocere</jats:italic>, “to hurt”) to various axonal pathways for the perception and modulation of pain by the central nervous system. The pathways carrying this afferent information depend on the class and origin of the nociceptors and the axons associated with them. Classically, the spinothalamic tract is identified as the main pathway carrying nociceptive information from the periphery. Other recognized nociceptive pathways include the spinal trigeminal tract from the face and smaller, less defined pathways from the thoracic, abdominal and pelvic viscera. This talk will focus on the organization of these three pathways throughout the central nervous system.</jats:p></jats:sec>
