What Is The Left Hemisphere Of The Brain Responsible For

Don't Miss

Right Brain Left Brain

The cerebrum is divided into two halves: the right and left hemispheres They are joined by a bundle of fibers called the corpus callosum that transmits messages from one side to the other. Each hemisphere controls the opposite side of the body. If a stroke occurs on the right side of the brain, your left arm or leg may be weak or paralyzed.

Not all functions of the hemispheres are shared. In general, the left hemisphere controls speech, comprehension, arithmetic, and writing. The right hemisphere controls creativity, spatial ability, artistic, and musical skills. The left hemisphere is dominant in hand use and language in about 92% of people.

How Do You Activate The Right Hemisphere Of The Brain

Here are three right brain exercises you may want to try:

  • Exercise #1: Connect the Dots. Identify something on the left side of your field of vision, and something on the right, and move your eyes back and forth between the two.
  • Exercise #2: Breathe Through Your Left Nostril.
  • Exercise #3: Tickle Your Funny Bone.
  • Communicating With Stroke Survivors Who Have Aphasia

    While it may be difficult to communicate, people with aphasia have several options when interacting with others.

    Some of these options include:

      Conversely, for those people without aphasia, communicating with stroke survivors who have aphasia can be made easier with some of the following methods:

      • Using pictures or props to make conversation
      • Drawing or writing
      • Speaking simply and slowly

      The Cerebellums Left And Right Hemispheres

      The cerebellum also has two hemispheres: the left cerebellar hemisphere and the right cerebellar hemisphere. Just as the longitudinal fissure divides the cerebrums hemispheres, the vermis separates the cerebellums hemispheres.

      Where Did The Myth Come From

      The concept of left-brained and right-brained individuals appears to stem from research in the 1960s on split-brain patients, whose corpus callosum had been separated. The research revealed that patients responded in different ways to stimuli such as images, depending on which brain hemisphere perceived them.

      What Is Right Brain

      The right brain is the right hemisphere of the brain, which is responsible for creativity, intuition, and impulsiveness. It processes the information in whole concrete images, not step-by-step methods to reach the final conclusion. Therefore, it has difficulties in understanding parts of a whole image. Also, the right brain faces difficulties in sequential thinking and it has to be trained in sequencing skills with the use of visual images or concrete materials.  

      Figure 2: Brain Lateralization

      The right brain may have difficulties in working with measurements, time, size, fractions, money, word problems, algebra, and geometry. It may not follow oral instructions without a visual demonstration. 

      The Cerebellums Inner And Outer Layers

      Like the cerebrum, the cerebellum has two layers: one inner and one outer. The outer layer is called the cerebellar cortex. Like the cerebral cortex, it is full of gray matter. Functions such as movement, motor learning, balance and posture happen here.

      Underneath the cortex lies the cerebellums white matter. Called arbor vitae for its appearance, the cerebellums white matter contains cerebellar nuclei. These neurons are vital because they relay information between the cerebral cortex and the peripheral nervous system to assist in learning and cognitive functions, motor control, balance and coordination.

       

      Before We Get Carried Away With Brain Synchronization Its Important To Note That Your Brain Has Evolved Into Two Separate Hemispheres For Important Reasons

      It doesnt seem feasible for the hemispheres to fully share information or to operate in a fully unified fashion. Moreover, in a lot of cases, keeping things separate is the smarter way for the hemispheres to function. Dividing up tasks and allowing the hemispheres to work semi-independently and take different approaches to the same problem seems to be a good strategy for the brain just as it often is in partnerships between people.

      Kara D. Federmeier, cognitive neuroscientist

      In order to survive, our brains evolved the ability to focus simultaneously on two things at a given time. The left brain is designed to focus on what you give your attention to a more narrow, detail and time-oriented design while the right brain stays available to focus on all the dangers and what ifs a broader and spacial oriented design.

      This is designed to keep you alive, in case youre minding your own business, observing some cool stuff and an unexpected danger comes your way. Or in nature while youre hunting and potentially being hunted.

      Pretty awesome right?

      So usually, thats how it works, although there are some specialized tasks that benefit from using both sides of the brain and various regions of the brain in communication.

      The Two Hemispheres And Brain Lateralization

      Brain lateralization is the idea that some brain functionsrely more heavily on one hemisphere than on another. One example of this is when we process language. The left hemisphere is in charge of language processing for the most part, whereas the right hemisphere only processes verbal information in relation to emotion. However, it has recently been that speech is processed in both hemispheres equally, so perhaps language is not as lateralized as we previously thought. 

      Likewise, it was believed that a left-handed persons brain was less lateralized for language development. That is, it was believed that these people would use more of the right brain hemisphere for language, contrary to the general right-handed population. It has been that this only happens in 1% of the left-handed population. 

      It was even found that the degree of lateralization of some brain functions may vary from individual to individual.

      Our brain is lateralized in some of its functions, however, most of these happen in both hemispheres. If a brain region or even a whole hemisphere is damaged or destroyed, other neighboring areas or even the opposite hemisphere may, in some cases, take over the activity typically performed by the damaged region. When brain damage interferes in the connections between one area and another, alternative connections can be developed to bridge the difficulties. This is only possible thanks to the brains great ability to adapt, which is called brain plasticity.

      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.

      We need to know how our minds work so we can work our minds better.

      How To Synchronize The Brain

      There are several ways that brain synchronization can be achieved.

      1. Meditation

      One of the most effective ways to create left and right brain synchronization is meditation. Meditation balances your left and right brain hemispheres and strengthens your corpus callosum.

      During meditation, the grand central station-like cable of nerves connecting your two brain hemispheres, the corpus callosum becomes deeply stimulated, much like a joggers legs on a long run.

      2. Exercise & Movement

      The left side of the brain controls the right side of the body, and the right side of the brain controls the left side of the body. Using both sides of your body uses and strengthens both sides of the brain improving coordination.

      You can also focus on crossing the midline of your body by touching one side of your body to the other, such as your left hand on your right knee. When doing so, your brain sends signals from one hemisphere to the other.

      3. Alternate Nostril Breathing

      This technique has been used by yogis throughout history to purify the nadis or energy channels in the body. The nasal cycle has been scientifically shown to be linked to the opposite hemispheric dominance.

      When your right nostril is dominant, the EEG measured activity in the brain is greater in the left hemisphere of your brain and vice versa. When the nostril dominance switches, so does the activity of the brain hemisphere.

      How to Sync The 2 Hemispheres of Your Brain for Better ...

      The human brain is an incredibly complex, hardworking organ. As one-half of the human nervous system, the brain structure oversees nearly all of the bodys operations, including how we move, think, feel and understand ourselves and the world around us. And knowing all this brain anatomy is important. From the cerebrum, cerebellum and the brain stem, to all the parts in between: this three-pound organ is what makes us humans, well, human.

       

      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. 

      What Did We Find

      What were our results? We found that older adults who get more brain exercise see things faster on the left side of the screen, compared with the right side of the screen. The more brain exercise an older adult has gotten during his or her lifetime, the stronger the right hemisphere becomes.

      This was an exciting result, because it suggests that brain exercise does strengthen the right hemisphere, and perhaps this is why brain exercise protects against Alzheimers disease.

      What should we do next? This is only a small piece of the jigsaw puzzle. Now we know that the right hemisphere is stronger in older adults who get more brain exercise. The next question is which parts of the right hemisphere are most important? For this question, it would be very helpful to use an imaging device called an MRI machine to take pictures of the brain before, during, and after brain exercise. These pictures would give us more detailed knowledge about exactly what changes in the brain with brain exercise.

      Where Is The Medulla Oblongata Located

      Your medulla oblongata looks like a rounded bulge at the end of your brain stem, or the part of your brain that connects with your spinal cord. It also lies in front of the part of your brain called the cerebellum.

      Your looks like a tiny brain joined onto the back of your brain. In fact, its name literally translates to little brain from Latin.

      The hole in your skull that lets your spinal cord pass through is called your foramen magnum. Your medulla oblongata is located at about the same level or slightly above this hole.

      The top of your medulla creates the floor of the fourth ventricle of your brain. Ventricles are cavities filled with cerebral spinal fluid that help provide your brain with nutrients.

      cranial nerves originate on this region.

      Your brain and spine communicate through columns of nerve fibers that run through your medulla called spinal tracts. These tracts can be ascending or descending .

      Each of your spinal tracts carries a specific type of information. For example, your lateral spinothalamic tract carries information related to pain and temperature.

      If part of your medulla becomes damaged, it can lead to an inability to relay a specific type of message between your body and brain. The types of information carried by these spinal tracts include:

      • pain and sensation

      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 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?

      Is Hemispheric Dominance Different Between People

      Hemispheric dominance varies from one person to another. The hemisphere of the brain used in every activity is not always the same for every person. Some experts believed that the activities of the brain are influenced by the persons right-handedness or left-handedness.

      Understanding which part of the brain is dominant in a person is essential in determining which learning style is more effective. Left hemisphere dominant people are visual learners. On the other hand, right-hemisphere dominant people are auditory learners.

      What Is The Brain Stem

      Life Sciences Database/Wikimedia Commons

       

      The final section of the brain is a mass of tissue and nerves called the brain stem. Located underneath the cerebrum and cerebellum, the brain stem connects the brain to the spinal cord. All information that goes from the brain to the body , must pass through the brain stem to reach its destination. The brain stem accounts for the remaining 5% of the brains mass, and is , the oldest part of the brain. The brain stem is responsible for regulating the heart and lungs, communications between the brain and the peripheral nervous system , our sleep cycle, and coordinating reflexes.

      The brain stem plugs the brain into the rest of the body through the spinal cord .

       

      Running throughout the brain stem is an area known as the reticular formation. This collection of nuclei plays a vital role in managing our consciousness and connecting with the various motor nerves to help us move our heads and faces, regulate our involuntary actions, and to help us chew, eat, breathe and see.

      What Is The Brain’s Anatomy And Function

      Left and Right Hemisphere of the Brain

      While no one is really left-brained or right-brained only, unless a hemisphere is damaged or removed, it is quite interesting to see how people test. Broad generalizations are made in popular psychology about certain functions on one side or the other. The brain receives messages through the five senses: touch, smell, sight, taste, and hearing.

      Actually, scientists continue to explore how some cognitive functions tend to be dominated by either side, that is how they are lateralized. The left side of your brain controls the right side of your body and vice versa for the right side.

      Both sides of the brain control different functions of the body. Each side of the brain is distinctly different from the other side because their functions are uniquely different.

      Brain anatomy is very interesting with the specific differences between the right and left side. For instance, a part of the brain called the lateral sulcus generally is longer in the left hemisphere than in the right hemisphere, but scientists do not always see any functional differences. If a specific area of the brain is injured, its functions sometimes can be assumed by another area of the brain. This is a very unique function of the brain.

      The right brain tends to think emotionally and artistically.

      How The Left And Right Hemispheres Work Together

      Both sides of the brain collaborate to handle major functions such as language processing and vision. But they are also, to a degree, specialized. Some areas of the brain are more active than others during particular tasks, and one hemisphere may be more involved than the other in specific parts of a larger mental operation.

      For example, Brocas area and Wernickes area are both linked to language and are most commonly located on the left side of the brain. Yet the right hemisphere is also known to play a role in language processing. Meanwhile, the limbic systemwhich includes the amygdalae and hippocampi and is involved in functions such as emotion and resides on both sides of the brain.

      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
      • Mathematics

      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.

      How The Brain Works

      The brain is our motherboard, storage, operating system, and more. The nuances of its functions canât be summarized in a black-and-white dichotomy, which is how the idea came around.

      The brain is divided into symmetrical left and right hemispheres. Each hemisphere is in charge of the opposite side of the body, so your right brain controls your left hand. The right hemisphere also takes in sensory input from your left side and vice versa. 

      The brain is segmented into regions called lobes. Your lobes isolate your brainâs functions to specific areas.

      • The frontal lobe controls your body movement, personality, problem-solving, concentration, planning, emotional reactions, sense of smell, the meaning of words, and general speech.
      • Your parietal lobe controls your sense of touch and pressure, sense of taste, and bodily awareness.
      • The temporal lobe governs your sense of hearing, ability to recognize others, emotions, and long-term memory. 
      • The occipital lobe controls the important sense of sight.
      • The cerebellum governs fine motor control, balance, and coordination.
      • The limbic lobe controls emotions. 

      For Planners And Management Scientists

      No, I do not suggest that planners and management scientists pack up their bags of techniques and leave the field of management, or that they take up basket-weaving or meditation in their spare time. It seems to me that the left hemisphere is alive and well; the analytic community is firmly established, and indispensable, at the operating and middle levels of most organizations. Its real problems occur at the policy level. Here analysis must co-exist withperhaps even take its lead fromintuition, a fact that many analysts and planners have been slow to accept. To my mind, organizational effectiveness does not lie in that narrow-minded concept called rationality; it lies in a blend of clear-headed logic and powerful intuition. Let me illustrate this with two points.

      • First, only under special circumstances should planners try to plan. When an organization is in a stable environment and has no use for a very creative strategythe telephone industry may be the best examplethen the development of formal, systematic strategic plans may be in order. But when the environment is unstable or the organization needs a creative strategy, then strategic planning may not be the best approach to strategy formulation, and planners have no business pushing the organization to use it.

      What Defines Left And Right Brained People

      • Resources

      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 Lefties…

      The Righties…

      So, are you are a lefty or a righty?

      The Left Brain Right Brain Myth

      While there is a left brain and a right brain, their use in popular culture has created a widespread misunderstanding. Itâs common to believe that the left brain is for logical thinking and the right brain is for creativity. People categorize themselves as being left or right brain-oriented depending on their interests and skills. 

      Scientists have been able to look closer at the brain and see that itâs more complicated than âleft = logical.â It wasnât until the 1960s when split-brain surgeries, a treatment of epilepsy, gave scientists the chance to investigate each half of the brain separately. 

      Scientists deduced that the left brain was better at language and rhythm, while the right brain was better at emotions and melody. However, this doesnât mean that the two halves are entirely separate. 

      The myth of the totally opposite hemispheres persists for a variety of reasons.

      • It satisfies the need for order. 
      • Like astrological signs, it gives people a defined personality type.
      • People naturally see creativity and logic as opposites.
      • People find the idea of having untapped creative power appealing.
