ANECDOTE

Trauma And Relational Patterns

  • Jennifer Wallace linked her fight response to childhood sexual trauma, relational patterns, and authenticity suppression.
  • She recognized fight arising across different contexts once she connected it to broader relational wounding.
INSIGHT

PAG Decides Our Survival Motor Plans

  • The periaqueductal gray (PAG) chooses the motor plan for fight/flight/freeze and gets tuned by past survival experiences.
  • Trauma sensitizes PAG pathways so lower cues trigger defensive motor patterns in the present.

PFC Loses Fuel During Threat

  • The prefrontal cortex downregulates during threat as fuel redirects to brainstem, reducing impulse control and reasoning.
  • Low metabolic resources make it harder to override automatic survival programs and increase reactivity.
