The Old Brain theme is the "lack of" (safety) that prompts a sympathetic "plus-reaction" (walking more, overexertion), whereas the New Brain theme of "Not trusting myself enough to support myself, not feeling respected, undervalued, and not appreciated" triggers a dorsal vagal "minus" reaction of restricted movement. Both are steps on the "autonomic ladder" and different answers to feelings and thoughts that originated in significant emotional experiences /UDIN moments.
