This area, which kicks in during forceful exhalations like coughing, laughing, or exercise, also appears to activate nerves that tighten blood vessels—raising blood pressure. When researchers switched off this region in experiments, blood pressure dropped back to normal, suggesting it plays a direct role in hypertension.
