Document Summary
Vagal highlights: potential noted in regards to vagal-lots of vagal activity. Vagal dollars: good resting vagus take it out (withdraw from bank) when situation is really challenging. Reserve so you have plenty to draw from: mammals have options to which part of the brain we use. Who is the type of person that has high resting vagus (relayed most of the time) In challenging situations, pull off brake ( vagus system) can pull of sympathetic system. If can stimulate vagus nerve artificially, this can help these people: measuring activation of smart vagus. Vagal fibres > spread out to target organs of body. Breathing out: surge in vagal nerve activation: heart slow down, longer breath out> slower heart beat. Measure beat to beat of heart, indirect measure of smarter vagus: vagal behaviour links. When babies are feeding/seeking > vagal withdrawl: smart vagus will withdraw , temporarily heart rate speeds up> metabolic faster ( nice homeostatic response= calm)
