The frontal lobes, the little brain down under and “Stayin’ Alive” (3/3)

__ [Editor’s note: Continued from Exploring the human brain and how it responds to stress (1/3) and On World Health Day 2020, let’s discuss the stress response and the General Adaptation Syndrome (2/3)] More on the Cortex, the Limbic System, and Stress: The cortex is made up of four major sections, arranged from the front to the back. These are called the frontal, parietal, occipital, and temporal lobes. Each of the four lobes is found in both hemispheres, and each is responsible for different, specialized cognitive functions. For example, the occipital lobe contains the primary visual cortex, and the temporal lobe (located by the temples, and close to the ears) contains the primary auditory cortex. The frontal lobes are positioned at the front most region of the cerebral cortex and are involved in movement, decision making, problem solving, and planning. There are three main divisions of the frontal lobes. They are the prefrontal cortex, the premotor area, and the motor area. The frontal lobe of the human brain contains areas devoted to abilities that are enhanced in or unique to humans. The prefrontal cortex is responsible for planning complex cognitive behaviors, the expression of personality, decision making, and social behavior, as well as the orchestration of thoughts and actions necessary for a person to carry out goals. A specialized area known as the ventrolateral pre-frontal cortex has primary responsibility for the processing of complex language. It is ...
