Lateralization Of Brain Function
The human brain is split into two distinct cerebral hemispheres connected by the corpus callosum. The hemispheres exhibit strong bilateral symmetry regariding structure as well as function. For instance, structurally, the lateral sulcus generally is longer in the left hemisphere than in the right hemisphere, and functionally, Broca’s area and Wernicke’s area are located in the left cerebral hemisphere for about 95% of right-handers, but about 70% of left-handers. Neuroscientist and Nobel laureate Roger Sperry has contributed significantly to the research of lateralization and split-brain function.
Scientific View Of Humanity
Modern science has a more prosaic, although no less extraordinary, view of humanity, properly placing homo sapiens as a single unique twig on the vast tree of life. It is unique for a reason. For all the connections to the rest of life on the planet, there is no doubting human uniqueness. For humans alone have looked to the sky and wondered about their place in the cosmos.
Humans alone have thought about thought. And, taking humans down a peg or two, humans alone have worried whether these pants have made their butt look big or whether anyone could tell that they were wearing a toupee.
Although these thoughts are not always grand and noble, they are thoughts. The ability to think in highly complex ways is what distinguishes humans from other species.

How Does This Neuromyth Impact Education
While the idea that people are more left-brained or right-brained may seem harmless, there are some real concerns about the existence of this myth in educators and students alike. Educators are increasingly encouraged to attend courses on brain-based learning. These courses often illustrate how ingrained these neuromyths have become. For example, some brain-based learning courses encourage educators to identify students as left-brained or right-brained and to adjust their teaching approach for these different learning styles. As a result, many teachers believe that this is a valid, scientifically backed idea. For example, in a sample of 242 teachers, 90 percent agreed with the statement differences in left-brain right-brain can help explain individual differences amongst learners. This is alarming given that this belief may influence the way in which teachers instruct specific students or groups of students and result in unconscious biases about a given students academic abilities .

Brain Process And Functions
The left hemisphere of the brain processes information analytically and sequentially. It focuses on the verbal and is responsible for language. It processes from details into a whole picture. The left hemisphere’s functions include order and pattern perception as well as creating strategies. The left hemisphere controls the muscles on the right side of the body.
The right hemisphere of the brain processes information intuitively. It focuses on the visual and is responsible for attention. It processes from the whole picture to details. The right hemisphere’s functions include spatial perception and seeing possibilities in situations. The right hemisphere controls the muscles on the left side of the body.
Key Differences Between Left Brain Vs Right Brain
The two sides of your brain look alike, but there are many differences between them and how they process information. Despite their differences, these two hemispheres of your brain cannot work without each other. Thanks to the research of the 1960s, psychobiologist and Nobel Prize winner Roger W. Sperry. It is only due to him that we can understand the differences: left brain vs. right brain and which part controls different thinking types. In psychology, this theory is based on the fact that two brain hemispheres function differently.

The Left Brain Is Mathematical And Logical
So like all maths problems it likes to be correct every time. Which is fine when you’re dealing with maths and 7 + 3=10 . Every thing has to be black and white.
It’s different when you’re drawing, or playing music or writing an article. You can have your black and whites and a range of rainbow colours. This of course drives your bully brain totally crazy. It’s trying desperately to pigeon-hole what you do into black and white. And of course, it fails. This sends you into a bit of a spiral as you consider the options to rationally solve the problem.
What Are The Differences Between The Left Brain And Right Brain
Many neuroscientists consider the concept of purely left-brain vs right-brain characteristics a myth. There are numerous theories and concepts that exist to explain how the right and left hemispheres of the human brain function. Many of which, have merits, and limitations.
Researchers Michael Gazzaniga and Roger Sperry proposed the concept of lateralization. In lateralization the left hemisphere and right hemispheres of the brain have very different functions, but they communicate with each other through their physical connections. An example of lateralization is language. For most people language function is located in the left hemisphere of the brain, particularly for right-handed people. The foundation for this split-brain theory often is based on research that has been performed on patients who had their right and left hemispheres of their brain surgically disconnected to treat severe epilepsy. Split-brain theory describes the left side of the brain as giving rational orders to the right side of the brain, and the right hemisphere as giving emotionally based commands.
Brain lateralization occurs in certain brain functions. In brain lateralization, certain regions of the brain perform specific functions. Many recent studies have shown that the right and left halves of the brain mostly are used equally, which shows the functional and physical connections between both the right and left hemispheres of the brain.

The Dangers Of These Misconceptions
So-called left brained people are described as: logical, analytical, and detail-oriented. Their worldview is objective and factual, so they are good at math, engineering and other fact-based tasks and careers. Right brained people are considered: creative, perceptive, intuitive, freethinkers. Their worldview is subjective and expressive, so theyre destined for creative tasks and careers.
These distinctions may limit your potential. Yes, some people are especially logical or creative, but that doesnt mean one side of their brain is more dominant than the other. Many logical tasks require creativity, and creative works are often rooted in logic. Thinking of peoples brains and personalities in such a divisive framework is false and restricting. Embrace what youre good at and let all parts of the brain do the work.

Here Are Some Faqs On Left Brain Vs Right Brain Theory:
1. Can a person be both left and right brained?
YES! You can be both left and right brained person. Even the test What do you see first gives the interpretation of you are both- left and right brained person. Depending on a situation demand either part of your brain dominates.
2. Do right and left brain see different colors?
Well, its a maybe situation here. There are various color perception images out there claiming that the color you see predicts which part of brain is dominates your thinking pattern. However, no one can really vouch for these ideas.
3. What jobs are good for right brain thinkers?
Some of the job profile that best fits the right brainers are: Managers
5. Which brain dominant is best?
While the right-brain dominance ensures that you are best at expressive and creative tasks. On the other hand, the left-brain dominance is reflected in your verbal and analytical aspects of life. This makes one point clear that both brain dominance have its own perks to offer. So, irrespective of the fact which brain dominates you it is at its best. No good, better, best comparison cannot be made here.
The theory of left-brain vs right-brain holds true only up to an extent! Recent research has found that this theory may be a myth!
To put it in a nutshell, the concept of left-brain vs right brain is better used in the form of a figure of speech than an anatomical description.

How To Develop This Side Of The Brain
Left-brained people often exhibit logical-mathematical intelligence, which is one of the nine intelligences defined by Howard Gardners theory of multiple intelligences. This enables them to be excellent mathematicians, scientists, and technicians.
Everyone possesses this type of intelligence to a certain extent. But people with left brain characteristics can especially benefit from improving it. They can gain a better understanding of logic by solving mathematical problems and immersing themselves in novel situations.
They can also benefit from spending time with friends who are interested in math and science. Their logical thinking will naturally improve.

What Are The Common Characteristics
The most common left brain characteristics include language, analytics, and logic, making them better at things, like reading, writing, and computations. Its known as the digital brain.
The left brain dominates the following abilities and aspects of our conscious mind:
- Thinking in words
Left Brain Vs Right Brain And Why It Needs Both
If you are unfamiliar with the theory, heres a quick primer from Ganes Kesari, co-founder and head of analytics for Gramener.
“A good example of left-brain thinking is working with numbers and analytics. AI and data science are often associated with left-brain thinkers in the IT profession, says Kesari. Building machine learning algorithms, AI models, and implementing statistical techniques are activities that call for logical thinking.
A great example of right brain thinking is design, he continues. Visual design and information design call for artistic abilities, and they are often associated with right-brain thinkers. Creation of data stories and compelling data visualizations need this creative quotient.
Although the traits of left-brain thinking are prized in IT, teams rarely succeed without a blend of both sides, says Kesari.
Another strong argument for right-brain thinking in IT? As more and more technical tasks are automated, theres a greater need for creative problem solvers to take the vision of IT to the next level.

The Part Vs The Whole
The right hemisphere pays wide-open attention to the world, seeing the whole, whereas the left hemisphere is adept at focusing on a detail of the whole. The right hemisphere, with its greater integrative power, is constantly searching for patterns in things. In fact its understanding is based on complex pattern recognition.
What Is Human Brain And How It Works
Each animal on planet Earthmammals, reptiles, fish, birds, etc. has a brain. Although the human brain is not the largest one, it is unique with some qualities. It is truly an amazing organ as it gives us the power to imagine, speak, and solve problems. Since it processes information that it receives from the sense and body and sends back the message to the body, our brain works like a computer.
Moreover, the human brain can do much more than machines like computers. Humans can think and experience emotions due to the brain, which is the root of human intelligence. Thus every part of the human brain has its own importance. That is why it is essential to know the differences between the left and right brain, especially those who need psychology assignment help.
The human brain is an intricate organ and weighs around 3 pounds. With 100 billion neurons and 100 trillion connections, your brain provides the central command of all you think, feel, and do. It divides into two halves: left brain vs. right brain. Each of these hemispheres controls specific functions. Besides this, there are several other sections of the brain, each with particular functions:
- Brain stem
These billions of nerve cells are arranged in patterns that coordinate your thoughts, emotions, behavior, movement, and sensation. It is only due to this brain communication can occur in split seconds. Now lets know more about our brain by making differences: left brain vs. right brain.

For The Teacher Of Managers
If the suggestions in this article turn out to be valid, then educators had better revise drastically some of their notions about management education, because the revolution in that sphere over the last fifteen yearswhile it has brought so much of usehas virtually consecrated the modern management school to the worship of the left hemisphere.
Should educators be surprised that so many of their graduates end up in staff positions, with no intention of ever managing anything? Some of the best-known management schools have become virtual closed systems in which professors with little interest in the reality of organizational life teach inexperienced students the theories of mathematics, economics, and psychology as ends in themselves. In these management schools, management is accorded little place.
Right Brain & Left Brain Functions List
Based on hundreds of experiments, scientists have made a list of features that are typical for each of the two hemispheres. The list above features just some of the everyday skills that the brain shows a left or right hemisphere preference for.
However, in everyday life, we use both hemispheres equally. How do we know? Neuroscientists have been studying brain injuries for many years. We know that if the left hemisphere is damaged, it leads to speaking, understanding, and coordination problems. When the brains right hemisphere is damaged, the patient has difficulties with visual perception, impulsiveness, and slow learning.

Is It Better To Be Left
After centuries of studying the brain, neuroscientists have come up with an answer. Theres no difference if youre more left-brained or right-brained.
Its best to meet in the middle and exercise both the left and right sides of your brain.
People who use both their right and left the brain to solve problems are able to successfully analyze situations taking into account emotions, as well as logical reasoning.
Those who use their left and right brain actively have a broad range of interests. For example, someone who is a left brain thinker like a scientist or mathematician will enjoy painting and playing the guitar on the weekends.
We can say the same for someone who is a right-brain thinker like a dancer or artist. As one of their hobbies, they might learn foreign languages and solve math problems.
In sum, its essential for both the left and right brain hemispheres to work together. They both need to find balance because one cant function without the other.
Planning On The Left Side And Managing On The Right
In the folklore of the Middle East, the story is told about a man named Nasrudin, who was searching for something on the ground. A friend came by and asked: What have you lost, Nasrudin?
My key, said Nasrudin.
So, the friend went down on his knees, too, and they both looked for it. After a time, the friend asked: Where exactly did you drop it?
In my house, answered Nasrudin.
Then why are you looking here, Nasrudin?
There is more light here than inside my own house.
This light little story is old and worn, yet it has some timeless, mysterious appeal, one which has much to do with the article that follows. But let me leave the story momentarily while I pose some questionsalso simple yet mysteriousthat have always puzzled me.
- First: Why are some people so smart and so dull at the same time, so capable of mastering certain mental activities and so incapable of mastering others? Why is it that some of the most creative thinkers cannot comprehend a balance sheet, and that some accountants have no sense of product design? Why do some brilliant management scientists have no ability to handle organizational politics, while some of the most politically adept individuals cannot seem to understand the simplest elements of management science?

Checking The Veracity Of The Left
Taking this to the next step, people were told that if they were dispassionate and cerebral scientific whizzes, they used the left side of the brain, while the artsy, creative, caring people used the right side of the brain. It was just too easy an explanation. People are rarely so dichotomous, that is to say, thinking versus feeling. It is really quite peculiar. It is not at all difficult to imagine that a scientist would be sad when his kitten unexpectedly died. Nor is it so difficult to imagine a singer being a shrewd businessman or woman. The world is not either/or.
So, what is correct? Well, it is true that there are right- and left-brain differences. The biggest is, of course, that the left side of the brain controls the right side of the body and vice versa. That one is considered a no-brainer.
There is also handedness, meaning being left-handed or right-handed. That seems to arise in individual differences in the right and left brain and the development of the fine muscle control centers of the hand. But what is being considered is more about thinking and where that originates in the brain rather than such ordinary things as muscle control. And the reality is that thinking occurs all over the brain.
With studies like this, it is clear that the whole right-/left-brain idea is not real, at least not in the way that is often portrayed in the media and some classrooms.
