The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires. While modern imaging technologies allow researchers to follow the activity of individual neurons in the brain, they are not yet advanced enough to dissect the microvascular function at a comparable spatial scale. This gap hinders our understanding of cerebral small vessel disease and its contributions to cognitive impairment and dementia.
