What Does The Right Hemisphere Of The Brain Do

Do We Really Have A Dominant Left Or Right Hemisphere

Bo Burnham “Left Brain/Right Brain” Shot 4 Shot REACTION!!! – ‘He wrote this at what age??

Contrary to popular belief, our brains are not actually two distinctive spheres. Rather, something called the Neocortex is and it makes up two-thirds of the brain. Therefore, it makes more sense to examine what goes on in the Neocortex the most advanced part of the brain, than concentrate on the hemispheres.

No matter how lateralized the brain can get, though, the two sides still work together, science writer Carl Zimmer

So, does one side of the brain really control specific functions? Is it possible for people to be either left-brain or right-brain? Despite the ground-breaking work by Sperry, more recent studies have cast doubt on the idea of dominance in either side of the brain.

Although it is still widely accepted that creativity resides in the right hemisphere, further research shows that language is, indeed, processed across both. In fact, the largest study on brain dominance showed no evidence to support the notion that people are intrinsically left or right sided in how their brains are wired.

What is true is that some people do prefer a creative and imaginative approach to life and learning, and others opt for a more methodical and logical way. Whichever one you prefer, right or left, it is worth trying to balance your strengths and recognise any weaknesses. Or if you cant, then at least utilise your preference and make the most out of your dominant style.

Tips For Keeping Your Brain Sharp

According to the Alzheimers Association, keeping your brain active via mentally challenging activities, like learning a new skill, may have benefits for brain health in the short and long term. They also suggest that a lack of mental stimulation may increase the chance of developing Alzheimers disease.

Here are a few tips to stimulate your 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.

What Happens If The Cerebral Hemispheres Are Damaged

Despite the hardness of our skulls, brain damage is a relatively common occurrence particularly for people who engage in high risk activities. Of course, the extent of the injury or damage is what determines how quickly, and how well, a person will recover.

Symptoms of right hemisphere brain damage can include:

  • Inability to focus attention on a specific task, object, or verbal communication.
  • Left-side neglect. This term is used to describe the inability to acknowledge the left-side of the body, objects, or people. They may not be able to read the left-hand side of a page or shave the left side of their face.
  • Inability to reason or solve problems. They may not understand that there is a problem or that that there is a way to fix it.
  • Memory problems. People with right hemisphere brain damage may not be able to learn information or recall previously learned information.
  • Lack of social skills. Non-verbal cues may not be understood, and they may make inappropriate comments or not understand jokes.
  • Disorganized behavior and/or communication. This will take the form of forgetting to answer emails or losing information. The person wont be able to give accurate directions or explain processes.
  • Lack of insight. Often people with right brain damage are not aware that they are experiencing problems. This can sometimes make the condition difficult to treat.
  • Limited movement. They may struggle to move their limbs properly, particularly on the left side of the body.

Problems With Reasoning And Problem Solving

Generally, the left side of the brain is in charge of logic and reason. However, the right side contributes to those skills as well. Because the right side controls our imagination and helps us organize information, it allows us to perceive things more fully and generate creative solutions. If the right hemisphere of the brain is damaged, this can severely hamper a persons ability to identify and solve problems.

Left Brain Vs Right Brain

By Eagle Gamma, published May 18, 2021

The brain consists of twin halves, a left hemisphere alongside a nearly symmetrical right hemisphere.

Hemispheric lateralization is the idea that both hemispheres are functionally different and that certain mental processes andbehaviors are mainly controlled by one hemisphere rather than the other.

The left hemisphere controls the right hand side of the body and receives information from the right visual field controlling speech,language and recognition of words, letters and numbers.

The right hemisphere controls the left hand side of the body and receives information from the left visual field controlling creativity,context and recognition of faces, places and objects.

According to the left-brain, right-brain dominance theory the left-side of the brain is considered to be adept at tasks which are considered logical, rational, calculating.By contrast, the right side of the brain is best at artistic, creative, and spontaneous tasks

Treatment For Right Hemisphere Damage

Speech language therapy can be helpful for people suffering from right hemisphere damage and the first task is often to help the patient understand that they are experiencing problems. Visual aids are used to keep patients on task and you may need to repeat instructions several times.

Its important that a person with right hemisphere damage doesnt become overwhelmed by too much stimuli, so a quiet room is needed to give instructions. Tasks need to be broken down into small, manageable steps and the person giving them should stand at the patients right side.

Lateralization Of Mental Activity

The right hemisphere may dominate awareness and image of self and the relation of self, visuospatially and psychically, to the environment . Acute lesions of the right hemisphere more severely disrupt the sense of self than left-sided lesions. Right hemisphere lesions can result in failure to recognize profound deficits as noted above, such as cortical blindness or left-sided hemiplegia , respond appropriately to recognized deficits , or attend to the left half of extrapersonal and personal space. They can also cause the delusional belief that duplicate persons are impersonating well-known persons or delusional reduplications . The right hemisphere may dominate our sense of self and lesions in the right parietal lobe can impair our body image. Left-sided neglect, anosognosia, and anosodiaphoria can be explained by destruction of a module of cortex controlling body image and physical relations of self to the environment.

What Defines Left And Right Brained People

The human brain is the command centre of our bodies. It contains roughly 86 billion nerve cells, can generate up to 50,000 thoughts per day, and it can process information faster than a Formula One car can travel!

“Brain information can travel up to 268 mph!”

On top of all of this, it is widely believed that the structure of our brain plays a key role in shaping the different characteristics of our personalities.

Your brain has two sides, which are known as hemispheres. The left hemisphere controls the right side of your body, dealing with logical thought and linguistic functions. The right hemisphere controls the left side of your body, dealing with things such as our imagination, spacial orientation and intuition.

Extensive research into the two sides of the brain is what inspired Neuropsychologist, Roger W Sperry to develop his left brain/right brain theory.

Sperry developed the left brain/right brain theory in 1960. He believed that each human brain is either right or left side dominant. Each side of the brain controls different types of thinking and therefore different personality traits. He believed that some individuals utilise both sides of their brains equally, but most people have a tendency to think in either a more left or right brain way.

So, what is the difference between Left and Right-brainers?

At Habit Action we have a balance of left and right brainers in the team.

The Origins Of Right Hemisphere And Left Hemisphere

Before the 1980s, there were few studies on the different hemispheres of the brain. The classic thinking at the time was that the left side was responsible for most of the brains processing. Indeed, the right hemisphere was considered to be a minor structure, with some going as far to regard it as so mentally retarded it was not even conscious.

All that changed in 1981. Nobel-Prize winner, Roger Sperry had the opportunity to conduct live studies on the brains of epilepsy sufferers. He wanted to reduce or even eliminate their seizures.

Previous studies had shown that grand mal seizures involve both hemispheres of the brain. However, if they were contained in one hemisphere, the effects would be drastically lessened. In his now famous Split Brain experiments, Sperry cut the corpus callosum, the structure that binds the two brain hemispheres and found that seizures were reduced.

But it was the after-affects that caused such excitement. Sperry quickly realised that the right hemisphere was capable of much more than originally anticipated. Furthermore, each hemisphere displayed definite characteristics.

For example, Sperry discovered that the left hemisphere specialised in language and analytical tasks. The right hemisphere focused on space perception and emotion.

The great pleasure and feeling in my right brain is more than my left brain can find the words to tell you. Roger Sperry

    It’s time to rethink whatever you thought you knew about how the right and left hemispheres of the brain work together.

    Sometimes ideas that originate in science seep out into the broader culture and take on a life of their own. It’s still common to hear people referred to as “anal,” a Freudian idea that no longer has much currency in contemporary psychology. Ideas like black holes and quantum leaps play a metaphorical role that’s only loosely tethered to their original scientific meanings.

    What about the idea that some people are more right-brained and others more left-brained? Or that there’s a distinctive analytic and verbal style of thinking associated with the left hemisphere of the brain, and a more holistic, creative style associated with the right? Are these scientific facts or cultural fictions?

    An infographic reproduced just last month at Lifehack.org, for example, promises to explain “why you act the way you do” by revealing “which side of your brain you tend to use more.” An article at Oprah.com explains “how to tap into right-brain thinking.” And decades of research using behavioral and neuro-scientific techniques do reveal fascinating and systematic differences across brain regions.

    What’s surprised you most about the hemispheric asymmetries you’ve found in your own research?

    Using The Right Hemisphere Of The Brain

    People that have a dominant right hemisphere process information with what is known as visual simultaneity. In this manner, several diagrams are processed simultaneously.

    You could use the example of a container holding all sorts of tiny balls, each one being the same color of blue, except for one purple one. Someone who uses the left side of the brain more, would need to look at each and every ball to find the different one. This method of resolution is called Linear sequential. On the other hand, the individual that uses the right side of the brain more would be able to simply look at the entire group of balls to find the different one.

    People that use the right side of their brain more also have an excellent ability to do multiple things at the same time. They are more creative, spontaneous, and you could say, theyre more intuitive.

    If you want to develop the right side of your brain you could start by doing more creative tasks, like imagining a story , or go for a walk and pay attention to architecture, house facades, and objects that you find. Or, go for a walk to far away places and unknown areas where you live and try to orient yourself without a map. Also, try to do the things you always do in a more unconventional way, be more spontaneous, and dare to do things you dont do every day.

    The Geography Of Thought

    Each cerebral hemisphere can be divided into sections, or lobes, each of which specializes in different functions. To understand each lobe and its specialty we will take a tour of the cerebral hemispheres, starting with the two frontal lobes , which lie directly behind the forehead. When you plan a schedule, imagine the future, or use reasoned arguments, these two lobes do much of the work. One of the ways the frontal lobes seem to do these things is by acting as short-term storage sites, allowing one idea to be kept in mind while other ideas are considered. In the rearmost portion of each frontal lobe is a motor area , which helps control voluntary movement. A nearby place on the left frontal lobe called Brocas area allows thoughts to be transformed into words.

    When you enjoy a good mealthe taste, aroma, and texture of the foodtwo sections behind the frontal lobes called the parietal lobes are at work. The forward parts of these lobes, just behind the motor areas, are the primary sensory areas . These areas receive information about temperature, taste, touch, and movement from the rest of the body. Reading and arithmetic are also functions in the repertoire of each parietal lobe.

    As you look at the words and pictures on this page, two areas at the back of the brain are at work. These lobes, called the occipital lobes , process images from the eyes and link that information with images stored in memory. Damage to the occipital lobes can cause blindness.

    Right Brain Left Brain: A Misnomer

    The human brain is basically symmetrical, split down the middle: the right cerebral hemisphere receives sensory input from and directs movement on the left side of the body, while the left hemisphere governs corresponding functions for the right side.

    Symmetry only goes so far, howeverthere are differences, too. Yet in recent years, the two sides of the brain have come to symbolize two sides of human nature the left brain hailed as logical,analytical, and intellectual, and the intuitive right brain as the avatar of emotion and creativity. A host of popular books, educational strategies, and even therapeutic interventions have ensued, promising to enhance abilities and relieve mental maladies by optimizing function on one or the other side of the cerebral cortex.

    The reality is not so simpleand a good deal more interesting. And like so much in neuroscience, far from fully understood.

    Brain Hemispheres: Do We Use One More Than The Other

    Restless Legs Syndrome Has to do With the Brain Right? Wrong! It’s In the Legs Where You Feel It!

    A study from the University of Utah, USA, dismantled these myths:

    There is no evidence that people use one of the brain hemispheres more than the other. This group of researchers identified brain networks in charge of process lateralized functions , to see if it was true that some people used more one of the brain hemispheres more than the other.

    During the study, the researchers analyzed the brains of 1,000 people and found that no individual was consistently using one hemisphere over another. They concluded that no personality type is related to the greater use of the left or right hemisphere.

    Therefore, it is false that some people use one brain hemisphere more than another depending on their personality. Some functions may be specialized in a particular cerebral hemisphere, but the truth is that we use both hemispheres equally.

    Some functions may be specific to a particular brain hemisphere however, we use both brain hemispheres equally. Even though one hemisphere is specific for a function, it will always work better in continuous communication with the other hemisphere.Scientists cant even establish that the right hemisphere is our creative brain. Creativity is a very complex process. According to a study, creative thinking does not seem to depend on a single mental process or brain region. Nor is it particularly associated with the right brain, attention, low level of activation, or synchronization with the alpha waves emitted by our brain.
