Document Summary
Vagal dollars: two different brain stem nuclei, not clear on how we measure them. Not clear why having a lot of smart vagus is a good thing. And difference btw when at rest and when your challenged. Its your potential that was first really noted, having a lot of vagal activity when resting was found to be associated with a lot of good things. If you have a lot of these vagal dollars you can always withdraw that, just like having a saving account (allows you to take it out when you really need it the most) Vagal decisions/ vagal gears (unconscious: newer vagus and older vagus, and we as mammals have options on which brain stems we are using. Not only due species differ, mammals vs reptiles differ in what vagal system they use. Breathing out: how we can measure indirectly activation of the smart vagus. The longer you breath out, the slower your heart beats.
