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.
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 currently the Director of the Kinsey Institute Traumatic Stress Research Consortium at Indiana University Bloomington, [2] which studies trauma.
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 ...
Play therapy, the polyvagal theory, and DMM theory were combined in Hadiprodjo's doctoral thesis. [106] Combining the DMM with the Assessment of Parent-Child Interactions (ACPI, a music theory-based assessment), can allow the application of music theory to understand family attunement and nonverbal communication in the context of self-relevant ...
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.
Many of the Polyvagal theory tenets incorporated in the Somatic Experiencing training are controversial and unproven. The SE therapy concepts such as "dorsal vagal shutdown" with bradycardia that are used to describe "freeze" and collapse states of trauma patients are controversial since it appears the ventral vagal branch, not the dorsal vagal ...
Evan Mobley scored 21 points, Caris LeVert added 19 and the Cleveland Cavaliers rolled to a 130-101 win over the Brooklyn Nets on Monday night. Donovan Mitchell had 18 points and five assists, and ...
According to the Polyvagal theory developed by Dr. Stephen Porges, the "Social Nervous System" is an affiliative neurocircuitry that prompts affiliation, particularly in response to stress. [2] This system is described as regulating social approach behavior. A biological basis for this regulation appears to be oxytocin. [3]
