History of pain theory or tissue, set up a reverberating, self-exciting loop of activity in a pool of interneurons, and once a threshold of activity is crossed, these interneurons then activate "transmission" cells which carry the signal to the brain's pain mechanism; that the reverberating interneuron activity also spreads to other spinal cord cells that trigger a sympathetic nervous system and somatic motor system response; and these responses, as well as fear and other emotions elicited by pain, feed into and perpetuate the reverberating interneuron activity. A similar proposal was made by RW Gerard in 1951, who proposed also that intense peripheral nerve signalling
