This work presents, to our knowledge, the first mechanistic model of how the brain's threat response sets breathing rate and depth and how fast breathing recovers after stress. A threat signal from the amygdala, shaped by stimulus magnitude and by cognitive appraisal (coping capacity and perceived stress), drives the breathing-control center that receives lung feedback: stretch receptors slow breathing and airway receptors speed it up. A simple electrical circuit stores the threat signal and expresses recovery as one time constant.
