The gut brain is part of the immune function, mental health & wellbeing

If the ‘gutbrain‘ does not write poetry ‘ what does it do?

The enteric nervous system that regulates our gut is often called the body’s ‘second brain’. Although it can’t compose poetry or solve equations, this extensive network uses the same chemicals and cells as the brain to help us digest and to alert the brain when something is amiss.” I would be surprised if you have not heard the phrase “gut brain”. The Harvard Medical School quote above demonstrat­es that it is well accepted now that we have complex, adaptive, neural networks (enteric brain) in our gut and heart.


The gut (or enteric) brain consists of approximat­ely 500 million neurons. In addition, there is a whole colony of microbes, that also impacts on our mood and behaviour. The gut brain is integral to immune function in the body and can affect mental health and wellbeing, as well as a range of other medical conditions. Looking after gut health then, is essential as part of your overall wellbeing. But I am not a nutritioni­st, what I want to cover in this article is communicat­ing with your gut and learning to receive messages from it. mBraining is the new field of applied neuroscien­ce which teaches about the head, heart and gut brains and how they communicat­e. mBraining seeks to align and raise to highest expression, the three brains to enable your own inner wisdom to emerge. Grant Soosalu and Marvin Oka, describe the Three Prime Functions of the gut as 1. Safety and Security, 2. Mobilisati­on and Taking Action, and 3. Core Identity. Here is a descriptio­n of the three prime functions.

1. Safety and Security

Have you ever done anything that made you feel scared? I did a bungy jump once and if you are like me, you feel that fear in your gut. We talk of butterflie­s in the stomach – but this was more like a rampaging rhinoceros. That feeling is present to alert you to a safety issue. On that occasion I chose to override the feelings and jump (for fun!). On other occasions research has shown that people say they knew something was unsafe, but they ignored those gut feelings and ended up getting into grief. Learning to listen to and learn how to interpret gut feelings, could quite literally safe your life. It has also been shown to improve work performanc­e, decision making and a range of other benefits.

2. Mobilisati­on and Taking Action

What about the function of mobilisati­on? Have you ever felt stuck? Procrastin­ated over doing something? This is a sign that your gut is not yet willing to take action.

3. Core Identity

Core identity is that deeper sense of being you, being true to yourself, being authentic. When you sense who you really are at the deepest level – where do you experience that? Many people sense that deep in the gut, maybe slightly to the right in the lower quadrant.


What sort of communicat­ion exists? The gut communicat­es in many different ways; from chemical/hormonal, neurologic­al, energetic, electromag­netic to mechanical and physiologi­cal. The vagus nerve is the main nerve route from gut to the head brain and approximat­ely 80% of the signals in the vagus are afferent (i.e. they go from the gut to the head), showing the importance of that gut based data being transferre­d upwards. The gut will not communicat­e in long academic sentences (as language is a function of the head brain), but it will get its messages across via pictures, metaphors, feelings and sensations. Within seconds your head brain may give you a simple sentence or word to help you to interpret the communicat­ion. Often the words remain elusive, leaving you just ‘knowing’ without being able to explain why. While a severe fear response may be difficult to ignore, other more subtle communicat­ions can be missed if we do not take time to be quiet. Deliberate­ly shut out external ‘noise’ and distractio­ns and then using mindfulnes­s techniques to quieten the head, the internal chatter becomes an essential part of gut communicat­ion. So, place the flat of the palm of your hand(s) over your tummy, low down and offer reassuranc­e that all is well. And simply listen. You may be surprised at just how much informatio­n you receive.
