Advantages And Disadvantages Of The Brain

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

A fresh human brain does not resemble the stereotypical fixated human brain typically seen in textbooks or diagrams. Instead, a fresh human brain is rich in vasculature, extending across the entire surface of the brain. The brain, in a sense, is greedy, requiring twenty percent of the oxygen coming from the lungs and twenty percent of the blood pumped by the heart. Recently, the brain’s greediness has led to advances in medical brain imaging technology. The PET scan maps the amount blood flow through specific areas of the brain, allowing researchers to localize particular functions to precise areas of the brain. In the TED talk, Dr. Allen explains the function of the cerebellum, temporal cortex, and frontal lobe – areas of the brain whose functions were determined using PET scan.

An MRI is a way in which brain functions can be studied. This method creates images of the brain using a strong magnetic field and is often used by psychologists to observe brain structure and function as discussed by McRobbie (2017). Psychologists may ask patients to perform different tasks to analyse their function. The technique has a variety of benefits. Firstly, one research study used the spatial resolution of MRI as an advantage. (Yang, Kim & Kim, 2008). This study was conducted on patients with amnesia to investigate location of lesion within the hippocampus. This suggests that a strength of MRI is spatial resolution in being able to acknowledge

The brain can be considered the most complex organ in the body and the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists have identified areas within it that perform specific functions. This makes the brain interconnected by three different layers: the central core, the limbic system, and the cerebral cortex. All of which contain structures that regulate everyday life and psychological function.

Magnetic resonance imaging (MRI) - This technique uses a magnetic field and radio waves to create detailed images in cross section of the brain. The MRI machine allows producing 3-D images that can be viewed from different angles.

Imaging tests, such as a CT scan or MRI. These are used to create a picture of the brain.

In spite of this when glancing further into the human mind, both hemispheres share special lobes which each possess distinct abilities. Firstly, there is the frontal lobe which can be located at the foremost part of the skull and manages a persons emotions, reasoning, problem solving, speech and movement (motor cortex). Secondly is the temporal lobe that can be pinpointed near the bottom of the skull right above the cerebellum, and has to do with the perception and recognition audio stimulants and memory (hippocampus). Next is the occipital lobe found at the very back of the skull, as it handles an individuals many aspects of vision. Lastly, there is the parietal lobe that takes charge of the perception of stimuli like touch, temperature,

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

Neuroimaging is a tool employed by neuroscientists who look to analyze specific regions of activity. Often, delineating these regions of activity is difficult: brain anatomies vary from person to

When it comes to the human body, there is still much that we do not know about the brain. However, several recent scientific advancements are working on rectifying that; 3-D imaging, fMRI’s, making brains translucent, identifying proteins and structure, and several other discoveries or tools are working together to unlock the brain. People have long been asking questions about the brain, such as how neurons communicate and bond with each other, if they can distinguish between unhealthy and healthy brains based on differences between the two, and if it is possible to bring movement (of a sort) to the paralyzed or quadriplegic. Much of the motivation behind understanding the brain is the hope that illnesses such as Alzheimer’s, autism, and schizophrenia

Neurological injuries can manifest themselves in endless ways across a wide spectrum of physical, emotional, and developmental deficits. Within just one of these manifestations, aphasia, there is a wide range of variation based on the location and level of damage from a neurological injury. Aphasia encapsulates a spectrum of deficits. It is defined as a disorder of language acquired secondary to brain damage (ASHA). These disorders can manifest themselves as receptive, damaging to the ability to process speech, expressive, damaging to the ability to produce speech, or both. In most right-handed and some left-handed patients, aphasia results from a lesion in the left hemisphere (ASHA). I strongly believe that a comprehensive knowledge of aphasias

The MRIs were taken by a method called segmentation, which gave them enough details of the brain

In “Secrets of the Brain,” Carl Zimmer, a science writer and blogger, brings to us the new technologies that are unlocking the mysteries of how the brain works. Zimmer starts his article with his visit to a doctor in Boston, Massachusetts, Dr. Van Weeden and his colleagues, are working on a mapping the radio signals that the brain gives off. They have developed a scanner, which maps bundles of nerve fibers in the brain into grids. Weeden and his associates have been able to replicate finding grid patterns in the brains of monkeys, rats and human beings. Before he introduces us to the other scientists he has interviewed, Zimmer explains where the history of the studying of the brain originated.

The purpose of this paper is to pursue one important and fundamental aim: language and the brain are purely inseparable since it allows us to perform essential tasks such as generating, comprehending and expressing speech. With damage to the brain, individuals can no longer perform such tasks which can ultimately lead to many types of language disorders. The focus of this paper is Broca’s aphasia, a language disorder characterized by the inability to produce written and spoken speech. Damage to the brain can cause many types of speech impairments as well as comprehension deficits.

The human brain is a mystery that has been studied for centuries in attempt to understand how it functions. Scientists first thought that the brain was a structure that functioned a whole. It was in the early 1600’s where the first ideas of localisation of function in the brain started. At this time Rene Descartes discovered a tiny structure called the pineal
