Cells of the<unk>  include neurons, astrocytes, blood-brain-barrier epithelial cells, myocytes and pericytes. Other components come from the extracellular matrix. The brain has a very high energy need and no storage support which means that it has to take oxygen and glucose from the dynamic blood supply. Imaging has shown that areas of brain activity are supplied with an increased flow of blood. The cells of the<unk>  sense the needs of neural tissue and release many different mediators that engage in signaling pathways, and effector systems such as the myogenic effect; these mediators trigger the vascular smooth muscle cells to increase blood flow through vasodilation or to reduce blood flow by vasoconstriction. This is recognized as a multidimensional response that is acknowledged to operate across the cerebrovascular network as a whole.
