  Nociceptive-Specific neurons and Wide-Dynamic-Range neurons  
   
  An animated illustration demonstrating pain traveling from a hand touching a hot pot down the arm to the wide dynamic range (WDR) neurons and the nociceptive specific (NS) neurons.
An animated graph showing that Both Nociceptive-Specific neurons and Wide-Dynamic-Range
      neurons increase their rates of firing as the intensity of the pain stimulus
      (the hot pot) increases. Wide-dynamic-range neurons, however, show an
      accelerated increase in firing rate; these neurons are the most sensitive 
      to
      changes in stimulus intensity.
