<p>I have read that the enteric nervous system might be called a separate brain. I read further that there might be 3 or even 6 human nervous systems. Could any of these be considered a brain in the same sense as the enteric nervous system and what are the criteria for classifying some cluster of nerves (neurons?) in the body as a &quot;brain&quot;?</p>
