Our brain and passage of time
What factors, neurobiological or otherwise, influence our perception of time? Why does time seem to go faster as we age? Are there any protocols for "slowing down the clock" or ways to control our subjective experience of time? Thank you, and greetings from Argentina! (Come visit someday 😉)
Parasympathetic Nervous system: Polyvagal theory confusion
In class we learned that there are 2 parts of the autonomous nervous system the sympathetic and the parasympathetic. The first one I thought was for fight, flight, freeze. The parasympathetic for rest, digest and selfheal. Fine with me. Until I tried to make sense of the polyvagal theory, which says a part of the vagus nerve (which is parasympathetic) the ability to "freeze" (at least make it not move) a mammal long enough to communicate or play dead bug to not be eaten by a predator. I already asked a professor who said that "freeze" is part of the parasympathetic and that not only the sympathetic part overreacts under stress also the parasympathetic. As an example: there is too much digestive acid build (digestion=parasympathetic) so one gets gastritis from stress. And that the whole model is very simplified as a metaphor. So my questions are: Is the polyvagal theory scientifically up-to-date, proved and/or reputable? Would you locate the autonomous nervous system as a function in the brain or in the body?
