The theory was introduced in 1994 by Stephen Porges. [1] There is consensus among experts that the assumptions of the polyvagal ...
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 ...
Stephen Porges' polyvagal theory claims that the vagus nerve system is central to connecting these clusters. [14] Siegel's model of the brain attempts to simplify the complexity of brain formation in emphasizing interaction between the brainstem, limbic systems (hippocampus and amygdala) and middle prefrontal cortex.
Trauma Screening Questionnaire abbreviated as (TSQ) is a questionnaire developed for screening of posttraumatic stress disorder. [1] The TSQ was adapted from the PTSD Symptom Scale – Self-Report Version (PSS-SR). [2] This self-reported assessment scale consists of 10 items, which cover one of the main signs of PTSD.
