central nervous system (brain and spinal cord) neurons as well as
neurons in the peripheral nervous system (rest of the body) that are
responsible for pain, temperature and itch perception. This means that

determined from his blood."<br><br><br><a href="http://www.sciencedaily.com/releases/2015/05/150521120919.htm">http://www.sciencedaily.com/releases/2015/05/150521120919.htm</a><br><br><br></div>John : )<br></div>
