Parietal Lobe Function

The largest part of the brain "the cerebrum" is divided in to two hemispheres, each hemisphere have different functions and responsibilities in memory, reasoning and language. The two hemispheres are in close communication with each other via corpus callosum .

= In order to understand the complex nature of the frontal lobes, a synopsis of the anatomy of the relevant parts of the brain is pertinent. Each hemisphere of the brain is divided into four geographical areas: the frontal lobe, parietal lobe, temporal lobe and occipital lobe.

According to the theory of lateralisation developed by Robert Sperry and Robert Ornstein, the cerebral cortex in the two hemispheres perform the same motor and sensory functions but each of the hemisphere is specialized for different tasks. As the brain develops, the left hemisphere is superior in doing tasks that involve speech, language, reading, and writing. The right hemisphere shows superiority in tasks that involves creativity, intuition, facial recognition, non-verbal imagery, musical recognition, sense of direction, play and sports, learning experience and risk-taking. Lateralisation is developed for the task that is done, that is the right hemisphere is used for a particular function. This decision is influenced by genetics, childhood learning experiences and

According to Chapter 8, it mentions how, "the posterior parietal cortex plays an important role in integrating two kinds of information such as; in directing behavior by providing spatial information and in directing attention" (Chapter 8, pg. 191). Chapter 8, also mentions how "electrical stimulation to the inferior portions of the posterior parietal cortex, the patients experienced an intention to perform a certain activity and felt they actually performed it but in reality no action really occurred" (Chapter 8, pg. 192). In regards to TMS case studies in humans, it mentions how "that the posterior parietal cortex contains a mosaic of small areas that specializes certain movements such as; eyes,

The cerebral cortex is the largest outer most part of the brain. It consist of tissue known as gray matter which is made of neuronal bodies. The optimal function of the cerebral cortex is vitally important. All information necessary to sustain life is stored and processed in the cerebral cortex. The tissue are divided into the left and right sides which are joined together by the corpus callosum. The cerebral cortex is divided into four lobes, the frontal, parietal, occipital, and temporal lobe. Each area carrying its own set of functions and responsibilities. These four lobes together make up the primary somatosensory area of the brain which controls the five sensory systems in the brain taste, olfaction, touch, hearing and vision. These systems receive sensory information from the thalamic nerve projections. The primary motor area of the brain consist of a much smaller area located within

Cerebrum: The cerebrum is the main part of the brain, which has two halves, or hemispheres. The right hemisphere controls the left side of the body and deals with things such as creativity, music, and art. While the left hemisphere of the cerebrum controls the right side of the body and is in charge of language, problem solving, and math. The cerebrum’s many tasks are carried out by its outer layer, or its cortex. This has distinct areas that have different roles. Motor areas trigger movement; sensory areas deal with the senses, while association areas clarify information.

Within the two hemispheres are four lobes: the occipital lobes, pariental lobes, temporal lobes, and frontal lobes. The occipital lobes are responsible for visual processing including shapes, color, and motion. The pariental lobes, located in front of the occipital lobes, are involved in touch sensatino and monitoring the body's position. Located below the pariental lobes are the temporal lobes, which are involved with hearing and language. In the very front of the brain, behind the forehead, the frontal lobes are found. The frontal lobes are responsible for the coordination of movement and higher mental process such as planning, social skills,

It is a wrinkled surface that interprets sensations from ones body that includes sight, sound, and smell. This generates thoughts, problems, and controls voluntary movements, alongside storing memories. Alzheimer’s will start to designate this section of the brain causing stored memories to be compromised. The Cerebral Cortex consists of four lobes: the frontal, the parietal, temporal and the occipital lobe. Visual processing takes place in the occipital lobe, sitting at the back skull. The temporal lobe processes sound and language, which contains the hippocampus and amygdala. Greatly impacting memory, emotion, and receptivity. Lastly the parietal lobe gathers all senses and is crucial for spatial orientation and

Four lobes make up the cerebrum, these are the frontal, parietal, occipital and temporal. The frontal

In the second test, the experimenters found that while both sides of the brain could recognize an object via touch, only the left hemisphere can articulate it into spoken words. The right side can only express through nonverbal means. In the third test, both sides of the brain were able to identify objects that either is what is described or associated to what is described by the experimenter. From these tests and some others, the researchers were able to discover that each hemisphere of the brain is able to act independently within the confines of their confines. Both the left and hemispheres are able to processes the senses and have motor functions. However, each hemisphere has its own particular aspects that it specializes in; for example, the left hemisphere specializes in speech, while the right hemisphere specializes in spatial skills. As a result of this study, many other studies have been performed to determine the extent of the two brain theory. After these studies, the psychology community has adopted the concept that each hemisphere of the brain specializes in certain skills and functions but can also think on its own. This knowledge also has a more practical usage. Medical professionals and rehabilitation centers can utilize the knowledge of what part of the brain controls what to better help individuals recover from brain damage by knowing what to focus on during recovery and

Hemispheric specialisation is the idea that one hemisphere has specialised functions or that it applies greater control over a particular function. Both the left and right hemispheres are involved in nearly all functions. The left hemisphere specialises in verbal and analytical functions and controls the right side of the body, whereas the right hemisphere specialises in non-verbal functions and controls the left side of the body. The verbal functions from the left side of the hemisphere involves recognising and using words for reading, writing and speaking. The analytical functions involve breaking down a task and approaching it in a logical and sequential way especially used in solving mathematical problems. The non-verbal functions include

The cerebrum makes up three quarters of the brain. In the cerebrum, there is the ability to problem solve, move, think and feel (“Alzheimer’s Disease,”n.d.). The cerebrum can be divided into two halves, the right hemisphere and the left hemisphere. Each hemisphere has four lobes, occipital lobe, parietal lobe, temporal lobe, and frontal lobe. Each lobe has specific tasks. For example, the occipital lobe is responsible for visual images.

What is freedom? Many people have a different view of freedom. Some people can see freedom politically, financially, or freedom of expression. The meaning and views about freedom had changed throughout history.

The African Civilization posses several concepts that are misinterpreted by other people. The book, “Things Fall Apart” by China Achebe defines the African civilization, the culture, and the impact of their colony. At the start of the book, the character Okonkwo is introduced. He is a strong man who possesses wealth in the Umuofia clan. Okonkwo is afraid of weakness because it resembles women and creates a memory of his father.

The discovery of coffee had changed the cultivation and the way of trading in the civilisation. Although the origin of the coffee is not clear but for sure coffee is wide spread around the world and is loved by billions of coffee drinker. The difference in coffee varieties, geographical location, climates and agriculture practices across the world has brought different sensory qualities to the coffee. This is because the flavour of coffee begins early in the plantation stage where flavour precursor forms as the coffee berries develop and ripe. For example, caffeine, a nitrogenous compound that influence bitterness of a coffee is higher in Robusta than Arabica due to the adaptation of growing environment in the wild. (coffeechemistry.com,
