Science-Based: Neurobiology of the Flight Response

Science-Based: Neurobiology of the Flight Response — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

A research-grounded visual explaining sympathetic activation, autonomic evasion, and neuroception of environmental threat — why running off or bolting is a survival state, not deliberate defiance.

This infographic covers:

• Anatomical pathway: amygdala (threat detection), brainstem (survival command center), spinal cord (rapid signal relay), sympathetic nerves (activate body for escape)
• Common triggers: loud noises, crowding, chaos, unpredictability, bright lights
• The signal pathway: trigger appears → neuroception detects possible danger → amygdala and brainstem switch the body toward survival → sympathetic system increases heart rate/breathing/muscle readiness → attention narrows to escape → the person bolts, hides, runs, or urgently moves away
• What it can look like: running off or bolting, suddenly leaving the room, hiding under furniture, pacing or scanning for exits, looking "fine" until the body suddenly moves
• Why it gets misread: adults may see avoidance or "bad behaviour," but the visible running away is often the last part of a much bigger nervous-system story
• What actually helps: reduce sensory load and immediate pressure, move with the person toward safety rather than blocking escape, use calm brief language, notice patterns (exits, crowds, noise, transitions), support regulation first
• Grounded in peer-reviewed research (Porges 2022; Owens et al. 2021; Kushki et al. 2013, 2014; Godoy et al. 2018; Chu et al. 2024)
