Vagus nerve is responsible for balanceing many basic functions of the body, such as digestion, breathing and heart rate. It also plays an important role in controlling the parasympathetic nervous system responsible for calming the body and reducing stress levels. The nerve helps to regulate the release of hormones and cytokines that play a role in the body's immune response. It also helps to regulate inflammation and can regulate the release of neurotransmitters such as dopamine and serotonin, which plays a role in mood regulation
