MEET YOUR SECOND BRAIN
Frederik B O Nel (February 2018)
In the magazine, Very Interesting (issue 39, Jan/Feb 2018), an article titled “Meet your second brain” by Robert Matthews, is based on a book called The Mind-Gut Connection (2016, by gastroenterologist Dr Emeran Mayer.
This so-called “second brain” is a reference to our enteric nervous system (ENS), or, what we would describe as our digestive system. The point is that our ENS is in constant communication with our brain by way of the vagus nerve. What happens in our gut and our brain is in constant communication with each other. It seems as if this constant flow of signals between our ENS and brain can influence our decisions, mood and well-being.
