Cerebrovascular Physiology What is Cerebrovascular Physiology? Cerebrovascular Physiology refers to the way blood vessels in your brain work to supply energy for neural activity. Local blood vessels deliver oxygen by dilating to increase blood flow to active areas of the brain. Problems can occur if the blood vessels don’t function properly e.g. they have become stiff with age. In CUBRIC we are interested in understanding how the health of blood vessels could impact upon brain function.
