The gut-brain bond also helps us form memories

A set of neurons in our gut, called the “second brain,” interacts with our brain to communicate that we are full and don’t need more. A new research, published in the journal “Nature Communications,” states that the gut-brain interaction may have wider realms beyond this regulatory function.

The experiment of rats suggests that the brain-gut connection works like a GPS for the brain to form memories of their environment, which can be recalled to return to food locations, writes New Atlas.

Such explicit relation between the hippocampus memory activity and the vagus nerve that connects gut to the brain could open up new avenues in medical treatment if the findings hold true for humans, reports Live Science.
