Cerebral vascular reactivity (CVR) measured with whole brain blood-oxygen-level dependent (BOLD) MRI responses to hypercapnic stimulus (5% CO2) in obese pre-bariatric surgery patients prior to surgery, age-matched healthy controls, and young reference controls. a BOLD maps, showing regional changes in blood oxygenation in response to hypercapnia. b Whole-brain BOLD CVR responses by group. Data are mean ± SD
