In 1994, Dr. Stephen Porges, who was director of the Brain-Body Center at the University of Illinois at Chicago, has developed a unique perspective on the autonomic nervous system (ANS). Until then, it was thought that the ANS was composed of two systems or response mechanisms: the sympathetic, initiating the action, and the parasympathetic, deactivating and calming. Porges determined that there is a third extreme ANS response, which freezes and immobilizes the individual. He also determined that the vagus nerve, which is the tenth and longest, most diverse of the 12 cranial nerves that emanate primarily from the brainstem, mediates or influences two of the three systems. One is the parasympathetic nervous system, which shuts down the action and energy of the sympathetic response, replacing it with a calming response system.
