Stress and Tinnitus; Transcutaneous Auricular Vagal Nerve Stimulation Attenuates Tinnitus-Triggered Stress Reaction

Study from Helsinki on 171 patients.  (Impressive! Especially given Finland’s small size.) It has a measure I’ve never seen before. ie. “HRV age”.  Apparently the TAVNS decreased the patients’ HRV age by 9 years. Full article here. Front Psychol . 2020 Sep 17;11:570196. doi: 10.3389/fpsyg.2020.570196. eCollection 2020. Stress and Tinnitus; Transcutaneous Auricular Vagal Nerve Stimulation…

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…

TAVNS, or Non-invasive stimulation of vagal afferents reduces gastric frequency.

It is not surprising that transcutaneous auricular vagal nerve stimulation would affect the GI system since it is innervated by the vagus.  But this study makes the connection in an elegant way.  But pointing out that the end organ, the stomach, is affected by TAVNS, you see the actual, real life results of this intervention. …
