New imaging combines light and sound to watch brain oxygen supply in real time

The brain is a black box of densely packed neurons, blood vessels and immune cells, all locked away in a sealed skull. WashU's Song Hu has dedicated his career to unlocking that puzzle box by developing new ways to "see" inside. His team's newest innovation could give researchers a new view of how brain cells and blood vessels work together and what happens when the coupling between the two breaks down.
