What is the human brain model which describes the mechanism of relation between the brain activity level and stressor? What is happened in human brain?
It is still unknown what happens in human brain exactly, but in this moment, the following brain model is thought as the reason why the values of brain activity level changes in stressed condition. It is known that the Wernicke area and the Broca area of a brain play major roles in human speak. The Wernicke area is at the left side of lobe and functions to understand language. The Broca area in the frontal lobe controls the muscle of uttering organs. When a human thinks and wishes to speak, a sentence is generated in the Wernicke area and transmitted to the Broca area through angular gyrus and gyrus supramarginalls. The Broca area then receives the signals from the Wernicke area, merges it with emotion from the right brain, and controls the muscle of uttering organs. As a result, a human being generates voice that is meaningful sound of a human being. In the Shiomi model, it is thought that a lot of information signal would be simultaneously exchanged among various parts of a brain, an
