I think one of my favorite posters during SfN was with Theo Zanos and the work at the Feinstein Institute involving the vagus nerve. They were able to read insulin, glucose, and cytokyne signals going from the body to the brain. This is the first step in bioelectronic medicine, being able to read and write the information coming from the body. In this interview, we talk about the specifics in being able to read what the body is telling the brain.
