Metabolic measurements of the working frontal cortex in man

What does the cortex of human frontal lobe do? The best answer, at the moment, is that it participates in any form of structured brain work a subject can do when awake. Perception, voluntary action, thinking, remembering, calculating, reading, discriminating and speaking are all conscious activities that are characterized by an activation of prefrontal areas in conjunction with either motor areas or more posteriorly located cortical areas. This is one of the most important discoveries that has come from the metabolic studies on the human brain.
