The gut-brain axis
Just after publishing the article on Serotonin and stating that the gut and brain’s serotonin systems can be considered separate entities, out comes a piece of research to show that they are not separate entities.
Indeed, it is known that there is a gut-brain connection that I have also reported on multiple times previously. But researchers are still often in the dark as to how and in what different ways the gut and brain communicate with each other. These researchers at Flinders University developed a new neural tracing technique that helped to investigate this.
They found that the enterochromaffin cells that line the gut and are known to responds to and release neurotransmitters based on stimuli from what is in the gut, communicate to nerve endings. This, through process of diffusion (they are not directly connected to the central nervous system), stimulate pathways that go to the spinal cord and brain.
This therefore strengthens our knowledge of how this happens but also to expand healthcare into more holistic and positive (and potentially more effective and cheaper ways). This suggests, you can eat yourself to better mental health, to a degree at least.
