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.
Vagus nerve stimulation can also increase the release of important brain chemicals such as serotonin and norepinephrine, which help regulate mood and are typically low in people with depression ...
The vagus nerve is also responsible for regulating inflammation in the body, via the inflammatory reflex. [7] Efferent vagus nerve fibers innervating the pharynx and back of the throat are responsible for the gag reflex. In addition, 5-HT 3 receptor-mediated afferent vagus stimulation in the gut due to gastroenteritis is a cause of vomiting. [8]
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. The longest nerve in the ...
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.
This discovery that the vagus nerve controls the immune system led him to study the effects of stimulating the vagus nerve with electrodes to alleviate inflammation, called "the inflammatory reflex". [10] [11] [12] In 2007 he co-founded a company called SetPoint Medical which aimed to develop vagus nerve stimulation devices to treat autoimmune ...
The vagus nerve, named after the Latin word vagus (because the nerve controls such a broad range of target tissues – vagus in Latin literally means "wandering"), contains parasympathetic fibers that originate in the dorsal nucleus of the vagus nerve and the nucleus ambiguus in the CNS. The vagus nerve can be readily identified in the neck ...
vagus nerve stimulation, which involves implantation of battery-operated generator of intermittent electrical stimuli to an electrode wrapped around left vagus nerve. Some studies have been shown it to have greater than 50% reduction in seizures reported in more than half of patients.
