Our gut has the ability to learn behaviours thanks to the network of neurons within the wall of the gastrointestinal tract. Interestingly, learning and memory processes take part in the gut and could explain, for instance, the involvement of enteric nervous system in the onset of specific gut disorders.

Previous studies have shown associations between gut microbiota and the onset of autism spectrum disorders, especially in children with recurrent gastrointestinal problems. New research provides the first evidence of gut bacteria’s direct contribution to autism-like behaviors in mice.
