Intro Flashcards
Three organizing principles of polyvagal theory
Hierarchy – the autonomic nervous system responds to sensations in the body and signals from the environment through three pathways. Dorsal vagus (immobilization), sympathetic nervous system (mobilization) and the ventral vagus (social engagement and connection)
Neuroception- the ways our autonomic system responds to cues of safety, danger and life-threat
Co-regulation: reciprocal regulation of our autonomic states that we feel safe to move into connection and create trusting relationships
Principle of appropriate response
Every response is an action in service of survival, no matter how incongruous it looks from the outside. Encourage curiosity about cues of safety and danger rather than judgement/blame/shame. Approach with honor and respect.
What is the Social Engagement System
It is our “face-heart” connection, created from the linking of the ventral vagus (heart) and the striated muscles in our face and head that control how we look (facial expressions), how we listen (auditory), and how we speak (vocalization). It is through this system that we send and search for cues of safety.
Polyvagal Four R approach
Recognize the autonomic state
Respect the adaptive survival response
Regulate or co-regulate into a ventral vagal state
Re-story
Neuroception definition
The way our autonomic nervous system scans for cues of safety, danger and life-threat without involving the thinking parts of our brain. AKA Somatic signals that influence decision making and behavioral responses without explicit awareness of the provoking cues.Before the brain understands and makes meaning of an experience, the autonomic nervous system via neuroception has assessed the situation and initiated a response.
Autonomic Nervous System components
Two main branches:
1) sympathetic - found in the middle part of the spinal cord and represents the pathway that triggers us for action. Responds to cues of danger and triggers the release of adrenaline, which fuels flight or fight
2) parasympathetic branch - includes vagus which travels downward through key organs and upwards to connect with neck, throat, eyes and ears.
Two parts of vagus nerve
1) Ventral Vagal - responds to cues of safety and supports feelings of being safely engaged and socially connected
2) Dorsal vagal - responds to cues of extreme danger. Takes us out of connection/awareness and into a protective state of collapse (aka frozen, numb or dissociated).
Chronlogical origin of vagal pathways
First was dorsal vagal, originating in ancient vertebrate ancestors. Next was sympathetic branch and most recent is ventral vagal pathway
Top of the ladder
Ventral vagal state where heart rate is regulated, breath is full, we are tuned in. Feeling happy, active and interested and feelings the world as safe, fun and peaceful. Health benefits include healthy heart, regulated blood pressure, healthy immune system, good digestion, quality sleep and overall sense of well-being
Moving Down the Ladder
Sympathetic branch activates when something triggers us to sense danger. Heart rate speeds up, breath is short and shallow – on the move. World may feel dangerous, chaotic or unfriendly. Health consequences include heart disease, high blood pressure, high cholesterol, sleep problems, weight gain, memory impairment, chronic muscle tension, stomach problems and increased vulnerability to illness
Bottom of the Ladder
Triggered into shutdown, collapse, and dissociation. Feeling alone, hopeless, abandoned, foggy, too tired to think. World is dead, empty and dark. Health consequences include chronic fatigue, fibromyalgia, stomach problems, low blood pressure, type 2 diabetes, and weight gain.
Surviving vs thriving
surviving requires threat detection and the activation of a survival response. Thriving demands the opposite- the inhibition of a survival response so that social engagement can happen.
Vagus nerve composition, location and functions
80% sensory (afferent) and 20% motor (efferent).Below diaphragm is dorsal. Above is ventral.
Why does sympathetic arousal bring a sense of isolation which has its own inherent sense of danger?
Because being alone and not a part of a group was dangerous. With the ventral vagal no longer online in sympathetic arousal, we no longer feel that connection
