Brainstem Expiratory Neurons Drove Hypertension TL;DR: A brainstem region involved in forceful exhalation also appears to drive blood-vessel constriction, making it a possible target for some forms of neurogenic hypertension. Key Findings A forced-exhalation region joined the pressure mechanism: The lateral parafacial region, normally recruited for strong expiration, was active under hypertensive conditions. Blood-vessel nerves …
