Great paper! Thanks for posting it Patty.
A little tough for non-scientists to quickly grasp major nervous system components and the various acronyms. Here are _link_s to some Wikipedia entries to help understand the study results:
Autonomic Nervous System -
ANSRuns all of our body systems not under concious control. We can can modify some ANS controlled functions (like breathing) but when we relinquish conscious control ANS keeps on ticking.
Sympathetic Nervous System -
SNS Commonly referred to as fight or flight response.
Parasympathetic Nervous System -
PNS Commonly referred to as rest and digest response.
Writing this up helped me to understand
