Each red and blue point represents the average value of a ROI of a single subject during either normocpanie (blue) or hypercapnia (red). Black line: least square error linear fit of each scatterplot. Abbreviations: BOLD: blood oxygenation-level dependent; -CVR: cerebrovascular reactivity, CO2: carbon dioxide, %fMRI: mean percent BOLD signal changes, ROI: Region of Interest.</p
