When looking at the cognitive function, you will see that it is termed as an intellectual or logical process that makes a person aware, comprehend or perceive ideas (CNBC, 2009). Cognitive function includes characteristics of a persons perception such as, sensing, reasoning, and conception, imagining and remembering (CNBC, 2009).
Scientists and researchers have recognized that every wonder of a persons mind comes from their brain. There are many ways to demonstrate how brain cells maintain the cognitive processes (CNBC, 2009). The cerebrum is the section of the brain where the cognitive functions begins. The cerebrum is also known as the cerebral cortex, it takes up most of the brains mass within the skull (CNBC, 2009). The cerebrum is consists of four diverse areas in the brain, these areas are known as lobes. Each of these lobes has a particular function they are responsible for, these functions consist of speaking, emotions, problem-solving abilities, learning, movement and perception. Particular tasks such as speaking, reading, and learning will require coordinated processing from varied areas of the cerebrum (CNBC, 2009).
The cerebral cortex and lobes
Cranes consist of more than three regions; cerebrality, cerebellar layer, and the cerebellum (CNBC, 2009). Each region consists of a cluster of cerebral proteins, which consist of subunits that are known both collectively as the nuclei of various cerebrum structures, and which are known as nuclei of individual cerebrums or cerebellum cells. In both regions, each nuclei of the nuclei produce a specialized protein called N-terminal protein (NCA). Each nuclei production a specialized N-terminal protein, and the different proteins are distributed throughout the brain to produce the corresponding genes for the particular genes present in each particular nucleus in each particular body part.
Cranal nuclei are found in a wide range of human tissues for the purpose of developing, maintaining, and correcting various brain functions including reading, vision, and a number of other brain functions (including: visual, auditory, and hearing disorders).
The brain contains numerous areas that contain the specific and various cognitive functions that are necessary for daily activities. In general the brain is characterized by the central part of a nucleus called the nuclei, which is located within one of the three major brain regions referred to as the corpus callosum, nucleus of the hippocampus, or cerebellum. The cerebellum is a small brain region in the middle of the skull, it is part of the brain associated with various body parts ranging from bones, to the spinal cord, to the hippocampus and other structures of the body. In the right hemisphere, the frontal nervous system is located in the lower left quadrant of the brain. At this level, the brain contains at least about 16 neurons (or 2.6 million neurons) located in the hippocampus and other structures. In the left hemisphere, the prefrontal cortex is located in the middle of the skull. For an overview of these areas, see the Neuroscience section of the Journal of Sleep Disorders.
Misc. The central part of the brain are the frontal areas. These areas are connected to individual neurons in order to facilitate processing of spatial stimuli. In the right hemisphere the frontal area is located in the middle of the brain. These areas are also connected to the prefrontal cortex. In the left hemisphere, the left hemisphere is located at the middle of the brain. This includes prefrontal areas in which many areas of the brain function (e.g., the left hemisphere), while the right hemisphere, including parts of the hippocampus, is located in the right hemisphere (see below for descriptions of the connections that occur in the prefrontal, right hemisphere, and the amygdala).
Racial origin of the cerebellum cortex
The cerebellum is composed of four specialized areas: the medial septum (the lateral septa), the medial frontal septum and the left temporal lobe. The cerebellum consists of 4 specialized central regions (nuclei 2 to 4), the nucleus of the cerebellum, the left temporal lobe, and its anterior part (top of the right hemisphere). Each member of this segment of the brain contains 20 nuclei (two thirds of the
Inside the cerebrum there are fibers that pass signals from one cell to another. These signal transmitters are synchronized by chemicals created by the nerve cells. These chemicals are known as neurotransmitters (CNBC, 2009). The brains many cognitive functions rely on the neurotransmitter processes to bring together whatever indicator being delivered amid the different areas of the brain. Signal transmissions are needed to pass between the left and right parts of the brain for accurate cognitive functions to occur (CNBC, 2009).
Phineas Gage, a 19th century railroad worker basically had a life changing accident that propelled him into medical history. In 1848, Gage, who was 25 at the time, was the foreman on a crew cutting a railroad bed in Cavendish, Vermont. On September 13, as he was using a tamping iron to pack explosive powder into a hole, the powder detonated. The 43 inches long tamping iron, shot skyward, penetrated Gages left cheek, ripped into his brain and exited through the top of his skull, landing several dozen feet away. Though blinded in his left eye, he might not even have lost consciousness, and he remained savvy enough to tell a doctor that day, “Here is business enough for you” (S.Twomey, 2010).
Before Gage had his accident, he was a proficient foreman and capable of performing his job duties masterfully. Gages mind was well-balanced and he was basically looked upon as an insightful well-groomed gentleman; however, after his accident he was obstinate and a bit impatient. Gage was also disturbed, brutish and grossly disrespectful, showing little respect towards his fellow workers (Hernandez, 2008). It was instantly recognizable that something indeed had occurred to Gages mental
