What Is The Theory Of Localization Of Function

1071 Words5 Pages

The brain is the most important organ in our bodies, other than the heart and the liver. It controls what we see, touch, taste, hear, and smell. However, many scientist have wondered, how the brain does this and how it operates. This discussion has led to the development of the theory the localization within in the brain. Today this theory has been debated whether the brain actually does localize its functions or not. One theory states the brain localizes its functions in two hemispheres. The functions are either in the right side of the brain or the left side. The other theory is known as the theory of distributed functions, which states the brain functions are distributed throughout the brain.
What is the theory localization of function? …show more content…

To put it simply, Localization is understanding what parts of brain work and why do they do this. The theory states there are 10 parts of the brain, each of them has an effect that controls the brain. (Parts listed in figure one) According the theory, each of these parts control a specific function, like an engine to a car or a motherboard to a computer. For example, the one part of the brain known as the temporal lobe controls and processes information gained from the eyes. This is how we are able to see and visualize our surroundings. Also, the theory states that the brain is divided into two parts, each part has certain behaviors that more prominent on each side of the brain. In contrast to the theory of localization, is theory of distributed functions. This theory states that the functions in the brain are distributed throughout the brain with no regard to which hemisphere it is in. One famous study of localization was made back in 1868 on an injured railroad worker, named Phineas Gage, by Dr. John Harlow. Gage was involved in an accident in 1841 when a tampering bar was impaled through his head. Surprisingly he was not killed by the accident, he was even speaking a few minutes after the incident (injury seen in figure two) .

Dr Norman Doidge The Brain That Changes Itself Analysis

1371 Words | 6 Pages

For example, when researchers were working with the mental mirror box, a box that tricks the brain of a patient with a nonexistent limb that the limb is actually there by reflecting the healthy limb, they found that the individual feels as if the limb is present and healthy. Researchers also found that if an individual scratches a particular spot on his or her face, that fulfills the itching sensation that was previously felt on the nonexistent arm. This is because when one area of the brain is not being used, such as the arm map when the arm is amputated, another part of the brain map takes over, such as the face. This is an extremely interesting finding which explains why blind or deaf individuals experience such profound functioning in their other

James Watson once said, “The brain is the most complex thing we have yet discovered in our universe”. It is responsible for every single movement in our body; from thinking, learning, breathing, creating memories and more. But the brain is not always perfect. We all have occasional “brain farts” or misperceptions of the world around us. Sometimes we believe that we have experienced vivid moments that we have never actually been through.

Posterior Parietal Cortex Case Study

Leslie Posterior Parietal Cortex "The posterior lobe forms about 20% of the human cerebral cortex and is divided into two major regions, the somatosenory cortex, and the posterior parietal cortex. The posterior parietal cortex which is located at the junction of multiple sensor regions, projects to several cortical and subcortical areas and is engaged in a host of cognitive operations" (Behrmann, Geng, Shomstein) The posterior parietal cortex has most commonly been associated with visuo-spatial perception and spatial attention. However, evidence has involved it in a much wider range of cognitive functions.

Ap Psychology Chapter 1 Study Guide

One of the most complex aspects of being human relates to the state of consciousness. It offers perhaps the most varied of experiences, from the state in which people are in when they are not conscious to the representation of semi-consciousness to the full reality of the waken state. Cognitive neuroscience may be one of the most well-explored areas of human well-being, and yet there is still so much more to learn about the inner workings of arguably the most important organ in the body. Chapter 3 delves into the concept of consciousness and the two-track mind, in an attempt to explain everything from sleep issues to addiction to the hypnosis to the ways in which the brain processes just about everything. The brain is a highly complex organ that is responsible for everything from knowledge to personality and everything in between.

In the Crash Course video, I learned about the different structures of the brain. Franz Joseph Gall, the first phrenologist, introduced a new theory in the early 1800’s. Gall believed that a person’s personality was linked to the ridges and bumps on the skull. However, scientists today understand that the brain contains different parts that are responsible for specific functions. One system of the brain is commonly referred to as the “old brain”.

Incognito The Secret Lives Of The Brain Analysis

Incognito: The Secret Lives of the Brain by David Eagleman explores the inner processes of the brain to redefine how humans function as beings in everyday life. Eagleman makes a strong argument throughout the entirety of the book that who people are with a conscious mind is a completely different person than with an unconscious mind. Though people spend their whole lives trying to figure out who they are as a person—what characterizes them, their likes and dislikes, etc.—there is so much more hidden behind the complex workings of our brain that we overlook, not because we do not want to know but because it is just how the brain functions. Most of the processes of the brain are carried out without much thought, and people do not have to understand

We all would like to forget something but is not as simple as that shapes your existence. In “The Attic of the Brain” by Lewis Thomas talks about how humans want to control every aspect of the brain. He states “There is no delusion more damaging than to get the idea in your head that you understand the functioning of your own brain.” Essentially is only a delusion humans have and can never hope to achieve and only will hurt us, while this may be true or not who’s to say. He also talks about how we may want to “to take charge, guiding your thoughts”, like to repress some our memories like in a “trapdoor”.

Advantages And Disadvantages Of Structural Functional Theory

784 Words | 4 Pages

Structural Functional Theory Structural functional theory is a macro sociological theory that is based on the characteristics of structures, social patterns, social systems and institutions such as education, religion, leisure, media, economy and politics. If all these social institutions are organized and co-operate with one another around a set of core values functionalist theorists assume that the entire social system will function properly and efficiently. Society in structural functional theory has a view that it is an organized system of interrelated parts that are held together by shared values and established social arrangements that help maintain the system to be in a state of balance and equilibrium. Structural functional theory is a broad perspective in sociology and anthropology which sets out to interpret society as a structure with interrelated parts. Functionalism addresses society as a whole in terms of the function of its constituent elements; namely norms, customs, traditions and institutions (Vibha Desai, 2013).
