Not all blood vessels play equal roles in brain health. To uncover how the brain regulates its complex circulation, researchers built a detailed computer model of mouse brain vasculature. Focusing on transitional zone vessels—crucial links between arteries and capillaries—the model simulates how each segment adjusts like a tiny valve. It reveals how the brain stabilizes blood flow during pressure shifts or heightened activity, offering new insights into brain protection and potential breakthroughs in diagnosing stroke, Alzheimer’s, and traumatic brain injuries.
