RAVANS:TAVNS exhalation synchronized stimulation
This study by friend of blog Vitaly Napadow, looks at TAVNS (type of ear stim I use in the clinic) and the effect of timing with breathing, exhalation versus inhalation. They are also able to calculate second by second HF HRV. This detailed level of HRV monitoring is way beyond my capabilities. It gives me…

After I used TAVNS on these patients in the same day, I realized they had some things in common. Both very athletic and hard workers. One patient comes in for hot flashes/Pms, the other anxiety. Both of them had a pronounced drop in their LF/HF with the TAVNS. Is it reproducible? We will see. I’m…
Read MoreTranscutaneous vagal nerve stimulation may elicit anti- and pro-nociceptive effects under experimentally-induced pain – a crossover placebo-controlled investigation
I met Usichenko in Barcelona when I presented a paper there. He is also interested in the potential for auricular stimulation in mitigating health problems. In this study he looks at pain management. I posted previously about his work. In this paper they used the auricular concha, not the cymba concha. Cymba concha has a…
Read MoreFMRI Biomarker for TAVNS for Depression
If you substituted HRV for fMRI in this abstract, you would get the idea of what I’m trying to find using HRV. I’m collecting data to see if one can identify which patients/treatments are most like to correlate with clinical success. HRV is noninvasive and basically free, so it would be a real breakthrough. We’ll…

Read MoreThe 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…
Read MoreEnding Alzheimer’s: Dr. Bredesen and Rhonda Patrick Podcast
I’ve listened to this podcast once and am making my way through it again. I take a lot of what’s presented with a grain of salt. Dr. Bredesen has a book to sell, an algorithm to pump, and speaking engagements to nurture. On the other hand, I realize that Alzheimer’s is a focus of intense…
Read MorePTSD Stress Reduction Over Time: Daily TAVNS and HRV Ke.Co. edition
This data is quite encouraging. This case is a 65+ year old male with PTSD with resulting defensive ideation, and fear. As described in the last blog post. ” This produces behaviors consistent with fight, flight, or immobilization that fluctuate depending on internal state and interactions with perceived threat (17–19). Variations in these defensive response…
Read MoreNon-invasive Vagal Nerve Stimulation Effects on Hyperarousal and Autonomic State in Patients with Posttraumatic Stress Disorder and History of Mild Traumatic Brain Injury: Preliminary Evidence.
This study looks at TAVNS, transcutaneous auricular vagal nerve stimulation, and its effect on startle and autonomic challenge with tilt test. In this single visit study, the group “We hypothesized that vagal tone would increase and that emotionally modulated sympathetic nervous system activity would attenuate in response to tVNS.” Their result “The stimulation was well…

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.
