Tracing the origins of where ear VNS may have actually come from, seems accupuncture (needles) in the ear to stimulate the Vagus Nerve on a small trial of 18 patients - in Russia mind you - saw some potential autonomic improvements. Dr. Kevin Tracey regrets Vagus Nerve Stimulation being so widely used by the now "Ear Clip" based companies pushing the interventions. And myself, having as well experimented with taVNS, it really never did much for me, and many are highly unlikely to even be sticking the required needles in their ears and clipping electrodes to the needles... I will say, while in China (just 2 months before the pandemic shut down everything) I had been working on a in-ear Ultrasound VNS system, and that actually *did* substantially work. I know what Vagus Nerve Stimulation feels like, having had the luxury of Ph.D. advisors guiding placement, advising neurostim work, and the privilege to handle very expensive lab-grade Ultrasound targeting machines on the Cervical Neck Vagus Nerve Stimulation with Ultrasound, it's very obvious when you get it, and it's unlike what most people think its like. Anyways, here's his tweet, decide for yourself :D _________________________________________ Dr. Kevin Tracey Wrote on X: #vagusnerve has ~200 million views on TikTok. There are 176 trials of transcutaneous auricular vagus nerve stimulation (taVNS) registered on http://ClinicalTrials.gov. There are dozens of ear stimulators being promoted everywhere you look. Where did it all this come from in the modern era? In 2001, in the city of Tomsk, in Western Siberia, Russia, eighteen patients with coronary artery disease had acupuncture needles inserted 0.1 to 0.3 mm deep near the auditory passage of the ear, near where the auricular branch of the vagus nerve originates. Low-frequency impulse current, 15 minutes daily for 10 consecutive days, decreased heart rate from 76 to 63 beats per minute and blood pressure from 130/80 to 120/75 mmHg.

Hello I've started using this US 2000 device since about a week on my neck. I tried different intensities and settled on "low". It definitely helps me sleep, and I feel more relaxed (nothing more) after using it. However the next morning when I wake up I feel a lot of unexplainable "anxiety" or "fear". This occurs whether I sleep 8 or 10 hours. Could it be that my sympathetic nervous system is rebounding to re-establish balance the next morning ? I am aged 26yo. Any ideas ? Should I just keep using it for the month ?

Hell all ! Whew! the group is expanding faster than I envisioned ! I want to provide a "Full Scope" view of what you *can* do with the Vagus Nerve Stimulation Tech we have available (Once you get to LVL 2) but - which, if you read this post, will be able to see right here on the wall. 1) Vagus Nerve Cervical Stimulation with Ultrasound: You will be placing the Ultrasound on the left side of the neck - 2-5 Mins is good - Start Low and Work Way Up - Shouldn't Feel Anything from Ultrasound Itself - but effects can be very calming if used before bed, assisting in Sleep, and improving HRV. 2) Spleen Stimulation with Ultrasound: A relatively difficult spot to stimulate, get help if possible. But can definitely be done yourself too. Going to want 5 mins on Medium to High intensity, due to likelihood of imperfect placement, and it's going to be "peering" through rib cage window slits. Excellent for helping your body control inflammation globally. 3) Cerebral Ultrasound - Insular Cortex Stimulation: This targets a region of the brain that deals with your bodies memory of previous inflammatory responses. Thus, stimulation of this region increases brain neuroplasticity, and enables you to "move on" from previous cyclical inflammatory responses. (People associate emotional "pain" with an inflammation response - thus a painful memory (trigger) (trauma even) can produce an identical inflammatory spike throughout the body) - The Insular Cortex is where this happens. Highly supportive of Spleen Stimulation protocol. 4) Other uses have been explored for Lymphatic Drainage, but this is on a case by case basis, and typically utilized best when/if the body has some major lymphatic drainage issue (water retention / lymph swelling in specific parts of the body [such as left side of body near armpits] that may benefit from increased lymphatic drainage activity) - Ultrasound amplifies Lymphatic systems (also glymphatic brain cleaning is activated as well) - and is generally utilized for 5 minutes on Medium to High settings, as is comfortable on the body - and likely for 1-2 weeks until swelling has subsided.
