Amygdala Sensitization in High-Conflict Adults: How Childhood Threat Calibration Creates Lifelong Conflict Patterns Amygdala sensitization fundamentally recalibrates the brain’s threat detection system. Early-life adversity rewires the corticolimbic circuitry — the communication pathway between the amygdala and prefrontal cortex — so that the brain enters every interpersonal exchange already primed for conflict. This is not overreaction. It is a mathematically precise calibration that made survival sense in childhood and now generates disproportionate responses to everyday disagreements. In my practice, I consistently observe that the adults who appear most “reactive” are operating from a threat baseline their conscious mind never set. ...

Prefrontal Cortex Deficits in High-Conflict Personalities: The Neuroscience of Impulse Control Failure During Conflict The prefrontal cortex contains two distinct braking systems — the orbitofrontal cortex (OFC) and the dorsolateral prefrontal cortex (DLPFC) — that work together to regulate impulse during interpersonal conflict. When both systems hypoactivate simultaneously under emotional load, the result is a compound failure in top-down inhibitory control that standard cognitive assessments cannot detect. ...
