Special vascular cells adjust blood flow in brain capillaries based on local energy needs

Researchers have discovered that a certain type of cell that sits on top of the brain's smallest blood vessels senses when their brain region needs energy. When glucose levels are low, these cells signal blood vessels to dilate, increasing the blood flow regionally and allowing more energy to fuel that part of the brain.
