Our intestines and brain are closely connected. The complex network of nerves and microbes in our gut, also known as the ‘gut brain’ or ‘2nd brain’, influences our mood, cognition and behavior. Communication between the intestines and the brain takes place via electrical wires (autonomous nerve fibers) and messenger substances such as neurotransmitters and hormones 1. Intestinal bacteria secrete an enormous amount of signaling substances, including serotonin and dopamine, which enter our brain via the bloodstream and influence our state of mind 23.
The intestinal microbiota, consisting of various microorganisms, has a profound influence on our physical and mental health.
These microorganisms, including bacteria, archaea and eukarya, have co-evolved with humans and have outnumbered our own cells. Collectively known as the ‘microbiota’, they contribute to various aspects of our well-being, such as digestion, metabolism and immunity.
Recent research has shown that the gut microbiota can also influence our brains and behavior via the gut-brain axis. The microorganisms in our gut can produce molecules that transmit signals to neurons, regulate brain activity, and influence cognition and emotional states.
Understanding this complex relationship between our gut and brain could lead to new treatments for mental illness. Although more research is needed, interventions such as probiotics and dietary changes show promise in modulating the gut microbiota and improving mental well-being.
