"Blood Flow Waves Mapped on Mouse Brain Surface"
TL;DR
NIH-funded researchers have visualized the full network of blood vessels in the cortex of awake mice, discovering rhythmic waves of blood flow that expand and contract the vessels. These waves, which occur independently of brain activity, may play a role in mixing brain fluids and removing waste, potentially impacting the understanding of neurological disorders and the interpretation of fMRI scans.
