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…

Clinical Data: TAVNS Transcutaneous Auricular Vagal Nerve Stimulation for Hypertension improves HRV

[et_pb_section admin_label=”section”] [et_pb_row admin_label=”row”] [et_pb_column type=”4_4″] [et_pb_text admin_label=”Text”] TAVNS for Hypertension best at 100HZ This blog post discussed a new study by (friend of blog) Vitaly Napadow, that 100Hz stimulation to the cymba concha was better than other frequencies in lowering blood pressure.  They did not look at HRV.  Here is some data from a…

Transcutaneous Auricular Vagal Nerve Stimulation Lowers Blood Pressure in Hypertensive Patients: Best at 100Hz

TAVNS for HBP Napadow A new paper by friend of blog Vitaly Napadow, which suggests that 100Hz is the best, if not only the only effective frequency for blood pressure reduction  in respiration gated TAVNS , or RAVANS.  They looked at 12 hypertensive women and saw reductions in both systolic and diastolic pressure with RAVANS…

Frequency-dependent functional connectivity of the nucleus accumbens during continuous transcutaneous vagus nerve stimulation in major depressive disorder

This is a nice study comparing sham to real Transcutaneous Auricular Vagal Nerve Stimulation to sham.  I The electrode set up looks good since the real TAVNS is situated in cymba concha and meatus. This is from the Journal of Psychiatry Research, but done in the Institute of Acupuncture & Moxibustion, China Academy of Chinese…

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…

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.

Transcutaneous Vagal Nerve Stimulation to the Neck

Study showing that stimulation of the vagus nerve in the neck elicits the same brain activity as invasive (implanted) vagal nerve stimulation, or auricular vagal nerve stim.  As patients and blog readers know, I study vagal response with HRV in the clinic in conjunction with acupuncture.  But I’m keenly interested in noninvasive vagal nerve stimulation…
