Abstract
It was once believed that cerebral blood vessels could not dilate and constrict independently and that the cerebral circulation was entirely under the control of the systemic circulation [see ref 1 for a historical review]. However, evidence accumulated over the past 100 years indicates that cerebral blood vessels are in a dynamic state. Thus, the cerebral vasculature is endowed with complex regulatory systems that allow the brain to finely regulate its own blood supply. One of the major factors that regulates cerebral blood flow (CBF) is neuronal activity. In this chapter, we will focus on the mechanisms governing the relationship between neural activity and blood flow with emphasis on the role of nitric oxide (NO) and cyclooxygenase-2 (COX-2).
