>*Main question: What make you stop stuttering, eventually? (after a long stutter block)* I think it's important to understand that the amygdala is not a single “fear button” but more as a salience / gating node that biases downstream motor and autonomic systems. “Tuning down” its sensitivity means either (A) changing the inputs that trigger it, (B) changing how it responds to those inputs, or (C) strengthening downstream circuits so the amygdala’s influence no longer blocks useful actions. A, B, and C may explain why stuttering eventually subsides after a prolonged block on a particular word in a specific situation. Your thoughts?
