The Gut-Brain Axis is a signalling pathway which exists between the gastrointestinal tract and the central nervous system. The communication between these two systems is largely affected by the composition of the gut-microbiome. This is because the gut-microbiome has an effect on hormone and neurochemical production, which has an impact on how we feel as well as on our behaviour. Gut-microbes have been suggested to be linked to many psychological disorders such as depression, anxiety and neurological conditions such as motor neuron disease and Alzheimer’s disease, through the gut-brain axis pathway.
