Phineas Gage Paper
Phineas Gage was a man who was a leader at his job and was a very likeable person. His family and friends agree that he would helpful to anyone, he was happy, and easy-going person. Then he received brain damage to his cerebral cortex, which is one’s cognitive functions are within their lobes located in the brain. Humans have four kinds of lobes located within the cerebral cortex that do different functions. Human Brain The human brain is covered with tissue known as the cerebral cortex, which large furrows (fissures) and small furrows (sulci), and there are ridges between the fissures and sulci known as gyri. Under the cerebral cortex tissue are four lobes, each lobe has a role in a humans cognitive functions. Phineas Gage was a man who received brain damage, and one will be able to see how it affected his cognitive functions. Four Lobes for Cognitive Functions

Basically the cerebral cortex is divided into four lobes; because during development of our brain the pressure divides the area into four areas and the development of these lobes do different functions within our brain. The four lobes are known as frontal lobe, temporal lobe, parietal lobe and the occipital lobe (Pinel, 2009). One’s occipital lobe is what gives him or her visual input and helps guide their behavior, the occipital cortex with “large areas of an adjacent cortex perform this cognitive function” (Pinel, 2009, p. 69). In, the parietal lobe it has two large functional areas, the post central gyrus function, which it analyzes sensations one can feel from his or her body, such as touch. In the posterior section of the parietal lobes has the role of “perceiving the location of both objects and our own bodies and in directing our attention” (Pinel, 2009, p. 69). The cortex of one’s temporal lobes, which has three functional areas. For one’s...
