Read MoreCore strength and Stress
Welcome to my world!! I guess I’m so used to seeing the connection between stress, immunity, and the physical body, that I’m surprised that it’s still in question. This is the original PNAS paper. Some excerpts from the interview: In the journal Proceedings of the National Academy of Sciences, the Pittsburgh neuroscientists showed that…

ABstract INS 2020 I will post this here. With all the uncertainty about Covid 19, the conference may be canceled anyway. For references, please click on link above Improving autonomic balance by decreasing sympathetic activity and increasing parasympathetic activity is of intense interest in the research community. Improved autonomic balance reduces inflammation implicated in medical…
Read MoreIs Stimulation of the Tragus as Effective as Stimulation of the Cymba Concha in TAVNS?
In this letter the authors make the case that tragus stimulation may be as effective as cymba concha. This would be helpful since the tragus is so much easier to use a clip on. Filing here for info. Though the tragus may not have the same density of fibers, they may be easier to reach,…
Read MoreNeural 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…
Read MoreUse of TAVNS in conjunction with Acupuncture for Anxiety: Ma.Co edition
I’ve been working on trying to get a single HRV measure of efficacy for transcutaneous auricular vagal nerve stimulation. Readers know that I look at many parameters since the “best use” procedures are far from established. Some advocate time measures such as RMSSD, others LF/HF a frequency measure that I’ve found to be a great…
