Document Summary

An unpleasant sensory and emotional experience associated with actual or potential damage. Direct one-on-one correspondence between pain and tissue damage. Hence, the greater the tissue damage, the greater the pain. Nerve impulses are sent to spinal cord transmission cells that are modulated by gating mechanisms. Large-diameter fibers carry non-pain information (touch, heat, cold, etc. ) and close the gate , while small-diameter fibers carry painful impulses and. Cortical descending signals also have the potential to inhibit message transmission and close the gate (beliefs, attitudes, attentional processes, etc. Emphasizes the role of the brain in pain reception. Pain perception can be generated by the output of the neuromatrix as a function of sensory inputs as well as of information from regions of the brain. Importance of reinforcement in the development and maintenance of pain behavior. If excessive pain behavior (complaining) is reinforced by attention, it tends to persist.
