I introduced the vagus nerve to Ben and discussed its health implications. He watched a video explaining what the vagus nerve is and how it impacts health. He took notes and we discussed. He watched a video demonstrating a palm press breathing exercise to balance the vagus nerve to get out of the fight-or-flight response. We practiced the breathing exercise. We then shifted gears to discuss the brain on drugs. He read part of an illustrated student handbook published by the National Institute on Drug Abuse that explains how drugs affect three different parts of the brain: the basal ganglia, the extended amygdala and the prefrontal cortex.
