The Nervous System And Your Gut Microbiome
Contrary to popular belief, your gut actually possesses its own ‘nervous system’. Comprised of its own neurons and ability to produce neurotransmitters. This is called your enteric nervous system, which has been said to function independently of your central nervous system (brain and spinal cord). Yes, that’s right, your gut quite literally has the means to act as a second brain!
The brain and the gut communicate via two pathways. Neural communications which include the vagus parasympathetic system and systemic communication which include the HPA axis, neurotransmitters, bacterial metabolites, and cytokines.
We have known for a long time that the vagus nerve plays a significant role in the
communication between the two organs. However, the importance of the systemic communication between the two have been also reinforced. In fact, evidence exists that the brain and gut still continue to communicate even when the vagus nerve is severed.
While many believe that the brain is the primary organ in charge of information transmission to the gut, your enteric nervous system actually sends far more information to the brain than it received from it. This reinforces the importance of gut health even further as research now shows that problems in your gut can have a direct impact on mental health.
