Scientists have uncovered how our brains quickly direct blood to areas that need it most, according to new research published in the journal Cell on July 16, 2025. A team led by Harvard Medical School researchers found that the brain uses specialized channels in blood vessel linings to communicate where blood is needed in real-time. “This work helps us understand how you can get that super-important blood supply to the correct areas of the brain on a time scale that is useful,” said Luke Kaplan, a research fellow in neurobiology at Harvard Medical School and co-lead author of the study. … Continue reading Harvard Study Reveals How Brain Efficiently Routes Blood Using Hidden Cellular Highway
