- The sympathetic side increases alertness, energy, blood pressure, heart rate, and breathing rate.
- The parasympathetic side, which the vagus nerve is heavily involved in, decreases alertness, blood pressure, and heart rate, and helps with calmness, relaxation, and digestion.
What happens when vagus nerve is stimulated?
- Vagus nerve stimulation stabilizes aberrant electrical activity in the brain by stimulating the vagus nerve with the help of an implanted pulse generator and lead wire.
- Anti-seizure medications don't completely work for about one-third of epilepsy patients.
Why is vagus nerve stimulation used?
- Vagus nerve stimulation (VNS) uses the vagus nerve to provide regular, gentle electrical pulses to the brain in an effort to prevent or decrease seizure activity.
- The procedure involves implanting a device under the skin in the left chest area.
