Vagus nerve stimulation (VNS TherapyÂ®) is designed to prevent seizures by sending regular, mild pulses of electrical energy to the brain via the vagus nerve. These pulses are supplied by a device something like a pacemaker. 1  The VNS device is sometimes referred to as a pacemaker for the brain..  The vagus nerve is part of the autonomic nervous system, which controls functions of the body that are not under voluntary control, such as the heart rate.
SHARES. The vagus is one of the larger more important nerves in the human body. One key role that it plays is as the âresetâ button to counteract when our alarm system has been set off resulting in the infamous fight, flight or freeze response as some type of threat has been perceived.lso note that the vagus nerve is the âvagabondâ nerve that wanders around and surrounds our heart and core area. It is heart-centered and noted as the nerve of intuition and the nerve of compassion. When we feel safe, without threat or anxiety, these abilities and inclinations are free to expand.
