In this short YouTube monologue, Nick Norwitz introduces a wearable vagus nerve stimulator called Pulsetto, describing how the vagus nerve connects the brain to vital organs such as the lungs, heart, and intestines. He likens the nerve to an internet cable that enables brain‑organ communication. Norwitz cites a pilot study reporting a 45% reduction in anxiety symptoms and a 56% reduction in depressive symptoms when using the device, and mentions anecdotal reports of life‑changing improvements for irritable bowel syndrome (IBS). He announces an upcoming masterclass on the vagus nerve, urges viewers to subscribe, and asks whether they would try the device.

This weird thing around my neck could improve my gut health and my mental health. It's a device that sends electrical pulses into my vagus nerve, the longest cranial nerve in my body, running from my brainstem through my neck and communicating with my lungs, my heart, and my intestines. You can think of the vagus nerve like internet cables, allowing my brain and my organs to communicate. And devices like this vagus nerve stimulator— this one's called Pulsetto— are becoming increasingly popular at the frontier of neuroscience. For example, in a pilot study, this device Decreased symptoms of anxiety by 45% and depressive symptoms by 56%. And some people report that it is life-changing for their IBS. So I'm going to be doing a whole masterclass on the vagus nerve. Click subscribe so you don't miss it. And tell me, would you try this?
