In response to performing physical activities, the body must adjust its blood flow in order to deliver nutrients such as oxygen and glucose to stressed tissues and allow them to function. Haemodynamic response (HR) in the context of neurobiology consists of the rapid delivery of blood to active neuronal tissues. Since higher processes in the brain occur almost constantly, cerebral blood flow is essential for the maintenance of neurons, astrocytes, and other cells of the brain.
Famous quotes containing the word response:
“Tears are sometimes an inappropriate response to death. When a life has been lived completely honestly, completely successfully, or just completely, the correct response to deaths perfect punctuation mark is a smile.”
—Julie Burchill (b. 1960)
