The vagus nerve. Polyvagal theory (PVT) is a collection of proposed evolutionary, neuroscientific, and psychological constructs pertaining to the role of the vagus nerve in emotion regulation, social connection and fear response. The theory was introduced in 1994 by Stephen Porges. [1]
Stephen W. Porges (born 1945) is an American psychologist.He is the Professor of Psychiatry at the University of North Carolina at Chapel Hill. [1] Porges is also currently Director of the Kinsey Institute Traumatic Stress Research Consortium at Indiana University Bloomington, [2] which studies trauma.
It would be placed in his ear and attached to a device that would send electrical signals to his vagus nerve, which carries signals between the brain, heart and digestive system.
A related theory—enhanced perceptual functioning—focuses more on the superiority of locally oriented and perceptual operations in autistic individuals. [74] Yet another, monotropism, posits that autism stems from a different cognitive style, tending to focus attention (or processing resources) intensely, to the exclusion of other stimuli. [75]
The polyvagal theory by Porges is an influential model of how the vagal pathways respond to novelty and to stressful external stimuli. [30] [31] [32] The theory proposes that there are two vagal systems, one that is shared with reptiles and amphibia and a second, more recent, system that is unique to mammals. The two pathways behave differently ...
This theory hypothesizes that toxicity and oxidative stress may cause autism in some cases. Evidence includes genetic effects on metabolic pathways, reduced antioxidant capacity, enzyme changes, and enhanced biomarkers for oxidative stress. [129] One theory is that stress damages Purkinje cells in the cerebellum after birth, and it is possible ...
The vagus nerve is part of the parasympathetic nervous system, often called the “rest and digest” system because it helps the body relax after periods of stress and regulates bodily functions ...
Being a husky owner isn't for the weak. It's not that they're bad dogs. It's just that they're HUGE drama queens. There has never been one situation where a Husky has maintained their chill.
