Abstract

This chapter presents a simplified overview of the brain in three dimensions. The vertical dimension shows the integration over time from the instinctive brain to the emotional brain and the cognitive brain. From the left–right angle, the two cerebral hemispheres have developed separate but complementary functions. From the back-to-front angle, the posterior part of the cortex is dedicated to perception according to regions that specialize in vision, hearing, or touch, and the frontal part is devoted to movement and abstraction, the prefrontal cortex overseeing thinking, action planning and relaying reason and emotion. The analogy of the theater stage, with a few interacting players, illustrates the conscious processing of information in the working memory. Our rationality, located in the frontal lobes, is unique to humans who give a central role to reason in directing their existence. But rationality remains limited even if it is enhanced by memory systems and external supports.
