Vagus nerve stimulation (VNS) therapy is a treatment for epilepsy that involves a stimulator (or 'pulse generator') which is connected, inside the body, to the left vagus nerve in the neck. The vagus nerve is essentially the queen of the parasympathetic nervous system - a. Breathing slowly, for instance, reduces the oxygen demands of the heart muscle (the myocardium), and our heart rate drops. The vagus nerve is basically listening to the way we breathe, and it sends the brain and the heart whatever message our breath indicates.It branches up to the ear and also down through your neck and all the way down to your intestines at the bottom of your torso. It exits the brain on the right and left of the brain stem which is situated in the middle of the back of your skull, slightly below the level of the ears. The vagus nerve is the longest of your cranial nerves. A 2008 study published in the journal Brain Stimulation (opens in new tab) found that vagus nerve stimulation resulted in an improvement in symptoms for patients with treatment-resistant anxiety.The increase in vagal tone can also help regulate stress and alleviate anxious feelings. In some cases, it is possible to stimulate the vagus nerve by improving your gut health. The Challenge Anxiety and depression are growing concerns, with 25.8% of the UK population self-reporting depression according to the 2018 Global Wellness report, with an estimated annual cost to the economy of £105 billion.The journal Frontiers in Neuroscience reported in 2018 that the poor function of the vagus nerve can lead to mood and anxiety disorders. In this project, the aim is to propose vagus nerve stimulation (VNS) to manage stress and anxiety. A certain amount of inflammation after injury or illness is normal. Here are nine facts about this powerful nerve bundle. The journal Frontiers in Neuroscience reported in 2018 that the poor function of the vagus nerve can lead to mood and anxiety disorders. The Polyvagal Theory provides us with an increased understanding of the ANS. The two branches of the vagus nerve are the ventral vagus and the dorsal vagus. The Polyvagal theory helps us understand that both branches of the vagus nerve calm the body, but they do so in different ways. Stephen Porges developed the Polyvagal Theory.
