Decoding the 'Wandering Nerve'
This article explains how Dr. Theo Zanos decoded the signals sent by TNF and IL-1 (both inflammatory cytokines) in the vagus nerve. The vagus nerve is made up of around 100,000 fibers, 80% of which are sensory and work to send information back and forth between the body and the brain.
Dr. Zanos recorded the activity of the vagus nerve and read that activity kind of how you’d look at radio frequencies, in order to understand the language of it: for instance, what fiber delivers which information and what direction is that information traveling, and what happens when we hone in on that specific fiber to electrically stimulate it?
Most importantly, what does this revelation do?
Well, if these guys understand the language of the vagus nerve, they can develop devices that customize stimulation based on that specific individual’s needs — (part of the movement toward precision-medicine!).
