On each side of the body there exists a tract of the vagus nerve that is part of the cranial nerves and extends to the abdomen. The vagus nerve regulates the proper functioning of organs from the larynx, heart and intestines.
Non-invasive vagus nerve stimulation (VNS) activates the nerve that connects several neurophysiological pathways that regulate neuroinflammation.
James Leonard Corning (1855-1923) first applied transcutaneous, electrical stimulation of the vagus nerve to treat seizures. In 1997 the FDA approved vagus nerve stimulation for seizures and epilepsy.
We have scientific evidence of VNS application in Depression, Mood Enhancement, Pain Relief, Improved Sleep and Anxiety reduction. Moreover, several studies now investigate its ability to modulate cardiac and inflammatory functioning.
Mechanism of action
The Orthosympathetic Nervous System (SNS) and the Parasympathetic Nervous System (PNS) are part of the Autonomic Nervous System, which typically regulates unconscious autonomic processes. PNS generally controls homeostasis and the body's response to rest and digestion. The SNS controls responses to a perceived threat and is commonly referred to as a "fight or flight" response.
Excessive activation of the SNS can lead to many chronic conditions favoring the appearance of levels of the so-called "Low Inflammation."
Vagus Nerve Stimulation has been shown to increase PNS activity, thereby decreasing SNS activity and reducing inflammation. Thus, we apply this stimulation to improve essential body functions.
