Left And Right Hemispheres Of The Brain Essay

It is still not fully understood whether or not the action of certain tasks is actually dependant on both of the brain hemispheres, because they both appear to have control over some tasks. An example of this, is the left hemisphere which is said to be responsible for the analytic part of the tasks, such as reading and making calculations. Within many individuals, it is also the dominant centre of language

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

activity, it must be a function of the body. However, if the brain is viewed as an extension of the mind, this statement is also proven untrue by what is known of human anatomy. The entire network that is the nervous system leads ultimately to the brain. In addition, it is known that the brain stem is largely responsible for controlling the electrical impulses that regulate involuntary

The human brain is a wondrous invention that has many scientists and researchers very busy to this very day. There are numerous qualities about the brain humans know about, yet there are still a great number of mysteries to the brain and how it functions left to be discovered and shared. Some facts scientists do know about the brain is that it is divided into to primary sections, called hemispheres. Each person has a left and right hemisphere of the brain. Each hemisphere is in charge of specific abilities, tasks, and functions. This paper will review what each hemisphere is responsible for and describe ways that each hemisphere is predisposed to learn.

The purpose of this paper is to evaluate the correlational method as a means for examining the relationship between functions of the left and right hemispheres. I will compare the performance of people with intact brains with the performance of so-called split-brain patients. In many ways, the brains of these two groups are very similar. 1a. The brain stem is found in the deepest part of the brain. The brainstem controls the automatic survival functions of the body, such as breathing. There are no differences between the function of the normal brainstem and the brain of a split brain patient. The brainstem will still supply the automatic survival functions of the body. 1b. The hippocampus is found in the limbic system along with the amygdala, the hypothalamus. The hippocampus is in charge of allowing the body to process information into memories. Without the hippocampus, there is no way for new memories to be created. There is no anatomical difference between the hippocampus in the normal brain and a split brain. 1c. The corpus callosum is found in the center of the brain. The role it plays as a part of the brain is it connects both the left and right hemispheres of the brain, allowing them to work and interact together as a whole system. The difference between the anatomy of the corpus callosum in a split brain patient versus someone without a

The collection of 100 bilion cells or neurons in the brain is divided into two halves, known as hemispheres.

Using a real human brain, Dr. Taylor explained the separation of the brain’s right and left hemispheres. The two cerebral cortices are completely separate from one another, but maintain communication via the corpus callosum. She described the right hemisphere as a parallel processor, thinking in images and learning from body movement. The right hemisphere is responsible for gathering sensory input, in the form of energy, from the environment around us. The left hemisphere, according to Dr. Taylor, is a serial processor, interpreting the sensory information gathered by the right hemisphere. The sensory information is analyzed and categorized by the linear and methodical thinking of the left hemisphere. Dr. Taylor believes the left hemisphere is responsible for interpretation of the past and future, as well as, an individual’s self-awareness. The

The results of this study show us the brain is not in fact symmetrical and the two hemispheres in the brain work in different ways. The left hemisphere is known to play the dominant role, which is in control of all complex behavioural and cognitive processes as for the right hemisphere it only plays a minor role. This report will further analyse how different the two hemisphers is the dominant side of the brain.

The human brain contains about 100 billion neurones, and has an average volume of 1200-1400mL. Once brain cells die, they stay dead forever.
The brain controls and regulates body functions. Without it you cannot survive. Damage to the brain is repaired slowly. Sometimes other parts of the brain take over the function of the damaged parts, but there are instances where brain damage is permanent.

The Cerebrum:
Associated with higher brain function, such as thought and action. The cerebrum obtains information from an individual’s surroundings and their body, and then sends that information to a specific part of the cerebrum. The cerebrum interprets this knowledge and decides what must happen next. The muscles and sensory information from the left side of the body is controlled by the right side of the brain, and vice versa.

Occupies more than 80% of the brain, and contains over 10 billions neurones. The folds in the cerebrum are called ‘convolutions’, and are used to fit more neurones and information in. These folds increase its surface area by three times. It is here that the high intellectual functions of humans take place. The cerebrum controls you conscious thoughts and the intentional (voluntary)

The brains left and right hemisphere are filled mainly with axons connecting the cortex to the brains other regions

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.

The right hemisphere of the brain is responsible for visualisation, creativity, imagination and negative emotions. The left hemisphere of the brain is responsible for logic, language, mathematics and positive emotions. Lateralisation or the specialisation of the two hemispheres of the brain allows the brain to function more effectively as each hemisphere becomes more efficient at communicating and processing information (Wolfe, 2010, p. 48; Woolfolk & Margetts, 2013, p. 72). When reading a story the right side of the brain works out the meaning of the story, whilst the left side of the brain is used for grammar and the arrangement of words (Woolfolk & Margetts, 2013, p. 72). Language is also processed in both hemispheres of the brain with the recognition of spoken words and sounds. The left hemisphere controls the production of speech. Plasticity also allows the brain to develop new or alternate pathways through experience, ensuring both hemispheres of the brain are communicating effectively (O'Donnell et al., 2016, p. 100). No activity involves the use of one single part of the brain but instead involves many different areas of the brain working together, so experts believe there is no such thing as right or left-brained

The left hemisphere controls the right half of the body that controls language and logical tasks. The right hemisphere controls the left half of the body creativity and emotions. Split-brain reveals that depending on what side of the brain is damaged, the two brain hemisphere may have information sharing problems, due to the separation of the corpus callosum . "a split-brain patient looking at an image through the left eye may not be able to name the picture because the information is only available in the largely nonverbal right hemisphere". Module 3.2 (n.d) The Nervous System.

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.

The brain was arranged in a matter that allowed the cerebral hemispheres to be at the top of the board and the brain stem at the bottom.
