Changes in Brain Blood Flow and Oxidative Metabolism During Mental Activity

PE Roland

Until recently mental activity was regarded as too subtle to have any effect on energy metabolism of the brain. Recent measurements show that when subjects perform pure mental activity regional cerebral oxidative metabolism and regional cerebral blood flow (which are dynamically coupled) increase in several areas of the brain, including the cerebellum. Different types of mental activity cause such increases in different parts of the brain.
