Could Vagus Nerve Stimulation prevent rapidly aging *brains*? This study seems to infer it's possible ! Recent research demonstrates that non-invasive transcutaneous auricular vagus nerve stimulation (taVNS) can reverse age-related memory decline by modulating the gut-brain axis. In 24-month-old mice, 30-minute daily taVNS treatments restored spatial and recognition memory to young-adult levels within four weeks. The discrimination index in recognition tasks effectively doubled, rising from 0.32 to 0.65. The mechanism involves a profound restructuring of the gut microbiome. Stimulation increased the abundance of beneficial *Akkermansia muciniphila* and *Lactobacillus* while reducing pro-inflammatory Proteobacteria. This microbial shift suppressed systemic inflammation, specifically lowering serum IL-6 and TNF-α. Concurrently, hippocampal growth factors BDNF and NGF increased, directly triggering neurogenesis and synaptic plasticity. Causality was confirmed via fecal microbiota transplantation. Recipients of "stimulated" microbiota exhibited the same memory gains as the original subjects, while subdiaphragmatic vagotomy neutralized all therapeutic benefits. These findings position taVNS as a viable, non-pharmacological pathway for rejuvenating the aging brain and preventing neurodegeneration through the body's internal interoceptive superhighway. https://med.stanford.edu/news/all-news/2026/03/gut-brain-cognitive-decline.html

Ive been targeting the Right Insular Cortex ever since I got my US-2000, on MEDIUM. It has been beneficial. Last night despite the warning, I tried it on HIGH intensity for giggles (I know, I know..). I thought I'd share my experience for the sake of science and anyone curious: In short it reminded me of a bad trip. Late at night I placed the device on my head, and within seconds I felt like my heart was racing, and that I was out of breath. I laid down on my bed, and my sense of self was dissolving, sending my brain into panic mode. Similar to the beginning of n drug induced EGO death. My mind was deepfried, struggling to form any coherent thought, while a rush of emotions came on, fear sadness surprise etc. Slept it off, but it was hard. Like trying to sleep on a bad fever. Waking up occasionally throughout the night, with incoherent thoughts calling me to act. Like there was something I needed to do or pay attention to. Conclusions: There was a lot of stuff stored in there. Targeting this area on HIGH triggered an intense rush that overwhelmed me. Completely different from MEDIUM intensity. Is it unsafe at this intensity ?

Welcome to the group! I know the first few modules are in the Classroom: Skool.com/vagus/classroom available to read right now - but I always see the same question pop up immediately: "What device should I buy?" Instead of *I guess* hoping you will make use of the Classroom which already has the answer, or hoping you would use the Search feature at the top of the site, I wanted to put the answer front and center. This post will be pinned at the top, so you can reference it anytime. The goal is to get you started with the right tool for your region. Let's break it down: USA: If you are in the USA: The US-1000 is your go-to. It’s affordable, incredibly effective, and the perfect entry point for Vagus Nerve Stimulation. For around $54 USD, it’s one of the most accessible biohacks you can invest in. The benefits—from reduced inflammation and deeper sleep to a calmer nervous system—are tremendous for the price. - 👉 Click for Module 2: How to Buy an Ultrasound - 👉 Click for Module 3: How to Use & Place Ultrasound 🌍 If you are in Canada: Great news, the US-1000 is also easily available. - Canada Supplier: Link EU: If you are in the EU or UK: The Rules are a Little Different Due to regulations and availability, the US-1000 isn't sold here. You’ll be looking at the US-2000 Pro class of device. Don't let the "Pro" name intimidate you! It simply means these units produce a higher power output and offer more focused stimulation. You don't really have a choice in the matter, but honestly, you're getting a slightly more powerful unit out of the gate.

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 ?
