For this study, the researchers used a non-invasive magnetic resonance imaging (MRI) technique known as the global blood volume and oxygen dependent (BOLD) signal to measure people's brain blood flow. The team used the whole-brain BOLD signal in people with and without obstructive sleep apnea (OSA)....
