The Pre-Frontal Cortex
The prefrontal cortex has been implicated in planning complex cognitive behavior, personality expression, decision making, and moderating social behavior. The activity of this brain region is considered to be the organization of thoughts and actions in accordance with internal goals. The prefrontal cortex area is responsible for executive function. Executive function relates to capabilities to differentiate between conflicting thoughts, determine good or bad, better and best, same or different, future consequences of any current activities, working toward a goal, prediction of outcomes, expectation based on actions, and social control. When analyzing and thinking about attributes of other individuals, the medial prefrontal cortex is activated. However, it is not activated when contemplating about the characteristics of inanimate objects. Several studies have indicated that reduced volume and interconnections of the frontal lobes with other brain regions is observed in patients diagnosed with mental disorders and prescribed potent antipsychotics; those subjected to repeated stressors; suicide victims; criminals; sociopaths; those affected by lead poisoning; and drug addicts. It is believed that at least some of the human abilities to feel guilt or remorse, and to interpret reality, are dependent on a well-functioning prefrontal cortex. It is also widely believed that the size and number of connections in the prefrontal cortex relates directly to sentience, as the prefrontal cortex in humans occupies a far larger percentage of the brain than any other animal. It is also theorized that, as the brain has tripled in size over five million years of human evolution, the prefrontal cortex has increased in size sixfold.
The Frontal Lobe
The frontal lobe is responsible for a large number of activities and functions we as humans are able to do. It is located directly behind the forehead and is most prone to injury because, it is in the front of the skull and is surrounded by rough ridged edges. The frontal lobe is responsible for planning, organizing, problem solving, memory, impulse control, decision making, selective attention, and also is responsible for controlling our behavior and emotions. People that suffer injuries to the frontal lobe usually suffer with language and memory malfunctions, impulse control, and social and sexual behavior. An individual’s personality also comes from someone’s frontal lobe. The ability to use your working memory also comes from your frontal lobe. Some might call it multi-tasking.
The Occipital Lobe
The occipital lobe is the visual processing center of the brain containing most of the anatomical region of the visual cortex. There are many extrastriate regions, and these are specialized for different visual tasks, such as visuospatial

hope to differentiate those disorders from what is considered to be normally functioning people and minds.

The brainstem, limbic system, and the cerebral cortex are the most important structures within the brain. The brainstem provides the ability for a person to survive from moment to moment through the breathing process and maintaining the consciousness. The structures of the brain stem are the…

Essay on Localization of Brain Function

Localization of Brain Function Psychologists have found that the brain often shows “localization of function”. This means that different parts of the brain carry out different tasks, for example, vision, voluntary movement and speech. The idea is that not all parts of the brain do the same thing, and that each part functions on its own, without the aid of other areas of the brain. This may seem obvious, but other organs, such as the liver, do not show localization of function; one part of the liver…

Broca's Aphasi A Case Study

Broca’s area in 1861 when he dissected the brain of his patient, ‘tan’, with an area of damage in the left frontal cortex, which resultantly became known as Broca’s area (Dronkers, Plaisant, Iba-Zizen & Cabanis, 2007). Due to Broca’s area being situated in the left hemisphere of the brain the main effect suffered is language problems, however there are often commonly associated weaknesses with the limb movement of the right side of the body. Broca’s aphasia, a result of damage to Broca’s area, is most…

The Brain1 Essay

The Brain The human brain is made up of four specific lobes. They are called the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The cerebral cortex is considered our “old brain” because its evolution can be dated back almost 500 million years, and the cerebral cortex is considered our “new brain” (Feldman, R. S., 2010). The central core and the cerebral cortex are extremely important. They control body and mental functions that are crucial for our quality of life. In the central…

Phonological Regulatory Loop Analysis

The purpose of this article is to identify what parts of the brain are involved in the articulatory loop component of working memory. This article was published in 1993 by E. Paulesu, C.D. Frith, and R.S.J. Frackowiak. Working memory is temporary memory that is used to interact and carry out immediate tasks. Working memory consists of the central executive, visuo-spatial buffer, and the phonological buffer systems. The articulatory loop is the part of the phonological buffer responsible for storing…
