Vagus nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an add-on treatment for certain types of intractable epilepsy , cluster headaches, treatment-resistant depression and stroke rehabilitation.
Joseph signed on and began using a non-invasive VNS device that delivers electrical stimulation to the vagus nerve through the ear, twice a day for 10 minutes at a time.
Vagal nerve stimulation implants can sometimes cause side effects, such as shortness of breath, site irritation or vocal hoarseness when the device is on, experts said.
A vagal maneuver is an action used to stimulate the parasympathetic nervous system by activating the vagus nerve.The vagus nerve is the longest nerve of the autonomic nervous system and helps regulate many critical aspects of human physiology, including heart rate, blood pressure, sweating, and digestion through the release of acetylcholine.
Knocking out vagal nerve receptors has been shown to cause hyperphagia (greatly increased food intake). [10] Neuroscientist Ivan De Araujo and colleagues have shown that the vagus nerve transmits reward signals from the body to the brain, [11] [12] potentially explaining how stimulation of the nerve leads to emotional changes.
Nerve-stimulation therapy can greatly improve symptoms of severe, treatment-resistant depression, a new clinical trial shows.. The results of the trial, published last month in a pair of studies ...
Measurements of vagal tone can be performed by means of either invasive or noninvasive procedures. Invasive procedures are in the minority and include vagus nerve stimulation by specific manual, breathing or electrical techniques. Noninvasive techniques mainly rely on the investigation of heart rate and heart rate variability. [4] [5] [6]
Stimulation of the auricular branch of the vagus nerve supplying the ear may also elicit a cough. This ear-cough reflex is also known as Arnold's nerve reflex (ANR), linked to the auricular branch of vagus nerve. It is an example of vagal hypersensitivity.
