Vagus Nerve Stimulation and Neurotrophins: a biological psychiatric perspective

Ok.  A whole new area of brain chemistry I wasn’t aware of.  I’m not even sure where Neurotrophins are found.  Will report once I know.  I’m tempted to buy this article, but don’t want to get carried away. https://www.sciencedirect.com/science/article/abs/pii/S0149763419310516 Review article Vagus Nerve Stimulation and Neurotrophins: a biological psychiatric perspective Author links open overlay panelPamelaRossoa1AngelaIannitellib1FrancescaPacittibcAdeleQuartinibElenaFicoaMarcoFioreaAntonioGrecodMassimoRallidPaolaTirassaa…

Dopamine mediates vagal modulation of the immune system by electroacupuncture.

Believe it or not, this might be relevant to the current covid crisis since patients are having a “cytokine storm”.  Possibly electro acupuncture would help.  It won’t happen, but maybe in the future. Dopamine Mediates the Vagal Modulation of The Immune System by Electroacupuncture Torres Rosas and Ulloa Abstract Previous anti-inflammatory strategies against sepsis, a…

Neural networks and the anti-inflammatory effect of transcutaneous auricular vagus nerve stimulation in depression

Full article link here PDF hereTAVNS and antiinflammatory effect on depression 202012974_2020_Article_1732 Abstract Transcutaneous auricular vagus nerve stimulation (taVNS) is a relatively non-invasive alternative treatment for patients suffering from major depressive disorder (MDD). It has been postulated that acupuncture may achieve its treatment effects on MDD through suppression of vagal nerve inflammatory responses. Our previous…

Vagus Nerve Stimulation Modulates Complexity of Heart Rate Variability Differently during Sleep and Wakefulness

This study is looking at direct vagal nerve stimulation in epilepsy patients.  Complexity is increased by vagal nerve stimulation during sleep, but not during wakefulness.  This is a confounding finding!  HRV with vagal nerve stimulation, both direct and through transcutaneous vagal nerve stim, is really befuddling. Ann Indian Acad Neurol. 2017 Oct-Dec; 20(4): 403–407. doi: 10.4103/aian.AIAN_148_17…

Current Directions in the Auricular Vagus Nerve Stimulation II – An Engineering Perspective

I’ve made the first pass through of this informative paper.  It discusses the current state of the art of TAVNS or aTVNS which is auricular (ear) vagal nerve stimulation.  There seems to be consensus that percutaneous needles with stimulation are the way to go.  Also that closed loop biofeedback will make the stim more effective. …

Vagus Nerve Stimulation Dramatically Reduces Inflammation Psychology Today

This article gives a great summary of recent studies into the vagus nerve and its role in health as the “rest and digest” side of the autonomic nervous system. Clinical and experimental studies indicate that stress and depression are associated with the up-regulation of the immune system, including increased production of pro-inflammatory cytokines…When administered to…

Benefits of Acupuncture for Inflammatory Bowel Disease

This abstract discusses some of the positive effects of acupuncture which help to mitigate the symptoms of inflammatory bowel disease.  Of course, of most interest to me is the effect on vagal activity.  Unfortunately, there is no full text online. Inflamm Bowel Dis. 2018 Dec 11. doi: 10.1093/ibd/izy371. [Epub ahead of print] Acupuncture in Inflammatory…

The Vagus Nerve Can Predict and Possibly Modulate Non-Communicable Chronic Diseases: Introducing a Neuroimmunological Paradigm to Public Health

This is a paper calling for monitoring of HRV and using neurostimulation for prevention of “non-communicable diseases”  ie cancer, heart disease, and other chronic non-infectious conditions.  It’s a combined effort of French, Belgian, and US researchers. I’m still picking my way through, but wanted to make this available to readers.  It comes at a good…

Electric Stimulation of Ear Reduces the Effect of Toll-Like Receptor 4 Signaling Pathway on Kainic Acid-Induced Epileptic Seizures in Rats

Study that shows benefit for ear stimulation, TAVNS, in rats with induced epilepsy.  I was unaware that epilepsy had an inflammatory component.  What condition doesn’t, I guess. Biomed Res Int. 2018 Feb 26;2018:5407256. doi: 10.1155/2018/5407256. eCollection 2018.
