Neuroscience: Controlled capillaries
Brian A. MacVicar1 & Michael W. Salter2
Abstract
The finest scale of blood flow through the brain occurs in capillaries. Suspicions that capillary flow is regulated by cells that put the squeeze on these vessels are now borne out by detailed experiments.
The control of brain blood flow poses an intriguing 'plumbing' problem. On the one hand, high overall flows are required to maintain healthy brain function, because in humans the brain accounts for 20% of the body's energy consumption even though it forms only 5% of the total weight.
