Whats Really Happening On Each Side Of The Brain

18-Are You Left Brained or Right Brained

Its not all fantasy. Certain areas of the brain do manage particular functions, such as movement and sight. For example, the left side of your brain controls your right arms and legs, and vice versa.

In the 1800s, neurologists Broca and Wernicke determined that their patients who were having trouble communicating had damage to the left temporal lobes, which suggested that the left brain controlled language, as explained by TedEd.

Additionally, Nobel Prize-winning research by Roger Sperry demonstrated in the 1960s that each hemisphere of the brain specializes in certain tasks. By studying epilepsy patients who have undergone a procedure that separates the left and right hemispheres of the brain, Sperry determined the left side of the brain handles analytical and verbal tasks, while the right half takes care of the spatial perception tasks and contributes emotional context to language.

Sperry explained, The great pleasure and feeling in my right brain is more than my left brain can find the words to tell you,’ according to

The results of this study and others have been misunderstood to link brain lateralization with individual personality traits, such as left brained people being logical and right brained people being perceptive. But according to Harvard Health blog, if you performed a CT scan, MRI or autopsy on the brain of a mathematician and compared it to the brain of an artist, you probably wouldnt see a difference.

The Truth About The Left Brain / Right Brain Relationship

    Its time to rethink whatever you thought you knew about how the right and left hemispheres of the brain work together.hide caption

    Its 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. Its 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 thats 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 theres 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, 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 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.

    Whats surprised you most about the hemispheric asymmetries youve found in your own research?

    What Research Says About Brain Functions And Dominance

    Several studies have debunked the old brain theory and straightened out information regarding hemispheric differences. Recent research has shown that the human brain has a symmetrical structure for a reason everyone uses both brain regions equally unless one side has been damaged due to a brain injury.

    After studying the brains of 1,000 people using an MRI, a 2013 scientific article published by PLOS One concluded that there’s no such thing as a dominant brain because a person uses both sides of their brain, depending on the task that needs to be completed.

    How the left hemisphere of the brain emerged as more dominant than the right stemmed from the split-brain study of neuropsychologist Roger W. Sperry in the 1960s, which won him the Nobel Prize. According to PLOS Biology, the study involved patients who had undergone split-brain surgery, wherein the corpus callosum connecting the two hemispheres was removed to address a type of severe epilepsy. After testing each hemisphere, the language centres were revealed in the left and emotional and nonverbal functions in the right.

    However, Sperry’s findings were exaggerated by many ill-founded publications that immortalised the popular belief that the right hemisphere is responsible for creativity in the world of art, business and education.

    Is There A Right Brain Vs Left Brain Test

    While recent research often contradicts the concept of strict right-brain vs. left-brain laterality, the way a person learns most effectively may be described by what is often categorized as left-brain or right-brain functioning. Brain Works software is thought to be an effective left-brain vs right-brain test. The test uses questions in the form of written text and graphs to calculate the dominant side of a persons brain.

    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?

    New Ideas And Reality

    Left brains are not famous for creative, ground-breaking ideas, but then again we arent really sure how the two sides of the brains work or dont work together. What we think we know is that the right brain can generate a new idea more efficiently and perhaps to a more intense degree than the left brain, whereas the left brain can take an idea and run with it. In other words, the right brain can initiate something but the left brain can handle the planning, processing, logic, etc. Total success is not possible without both sides of the brain firing on all cylinders.

    The left brain also seems to have a propensity for reality. You would not expect to find many metaphysical wanderings in the left brain. While this might limit the left brain in terms of considering all possibilities, it also prevents the left brain from getting lost in the impossible, unrealistic or off-topic. The left brain prefers to stay rooted in and focused on reality. This is the epitome of the left brain relying on logic, sequence, critical reasoning and self-sufficiency.

    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.

    What Does The Left Temporal Lobe Control

    To date, weve learned a lot about the brain, but theres still much more to be uncovered. What we do know has helped us identify and treat many medical ailments.

    As for the temporal lobe, its task is to control sight and sound processing, as well as language usage.

    It takes care of hearing and listening, visual input processing, and verbal material comprehension . The temporal lobe is also where our long-term memories are stored.

    So, the way we express ourselves in terms of language, and the way we understand art and music, is all thanks to the temporal lobe.

    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

    Left Brain Vs Right Brain: Characteristics Chart

    Neuroscientists and psychologists worldwide have put considerable effort into investigating the characteristics and functions of the left and right sides of the brain.

    Though the two sides of a humans brain look alike, they process information very differently. Over the years, studies have consistently shown that there are many differences between the left brain and the right brain. However, although the two halves work in two contrasting styles, they are very much interconnected.

    In this Custom Writing article, you will learn everything about the left and right brain hemispheres, including the differences in how they function.

    Left vs Right Brain âFind out which one works for you

    Why is it important that both the left and right brain hemispheres work in harmony? Its because they both contribute to a brains capacity for thinking. The two hemispheres of the brain connect to the corpus callosum.

    The cerebrum is the main part of the brain that deals with thinking. It helps with learning and language and assists with body movements such as walking and dancing.

    Which Side Of The Brain Is Dominant

    Differences between right brain vs. left brain characteristics and functions

    While no single theory completely explains the multiple complexities of brain functions, neuroimaging techniques show some distinct differences between the left and right brain hemispheres, which is referred to as lateralization.

    Examples of these differences include language function in the Broca surface area and Wernicke area of the left side of the brain, and emotional and nonverbal functions in the right side of the brain.

    The areas responsible for language tends to be on the dominant side of the brain, and opposite of the handedness of a person. For example, if you are left handed, the language function areas of your brain are more likely to be located on the right side of your brain. Moreover, if you are right-handed, your speech functions are more likely to be located on the left side of your brain.

    Left-brain characteristics and functions

    Left-brain functions are thought to include:

    • Understanding the sum of any situation, getting “the big picture
    • Large muscle movements like walking
    • Sensing where ones body is in space
    • Balance

    According to neuroscience research, the left side of the brain or hemisphere:

    • Is positively stimulated by new experiences.
    • Controls the immune system.
    • Is responsible for the involuntary bodily functions, for example, breathing, heart rate, and digestion.

    Right brain characteristics and functions

    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.

    Anatomical Properties Of The Left Hemisphere

    The left hemisphere constitutes the left region of the Encephalon . It is an inverse portion of the right hemisphere, but not inversely symmetric. As with the rest of the body, the left side of the brain is asymmetrical with respect to the right side.

    The left hemisphere is separated from the right hemisphere by a deep sagittal fissure located in the midline of the brain. This fissure known as interhemispheric or longitudinal cerebral cleft allows the establishment of anatomical differentiation between the two hemispheres of the brain.

    The interhemispheric fissure contains a fold of the dura and the anterior cerebral arteries. In the deepest region of the fissure is the hard body , A commissure formed by a conglomerate of white nerve fibers.

    The function of the corpus callosum is to connect both hemispheres across the midline and transfer information from one side to the other. In this way, the left hemisphere works together with the right hemisphere, thus providing an integral and joint brain activity.

    Like the right hemisphere, the left hemisphere can be divided into four large Brain lobes : he Frontal lobe Located on the front of the skull, the occipital lobe Which is in the posterior region , the Parietal lobe Which is located in the upper region of the brain, and the temporal lobe that lies in the medial region.

    The Dangers Of These Misconceptions

    Do People Really Have Right or Left Brain Personalities?

    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.

    What Does The Left Side Of Your Brain Do

    The left side of your brain controls the muscles on the right side of your body, and it is responsible for language along with logical and mathematical thinking. Meanwhile, the right brain controls the muscles on the left side of your body, and it is associated with spatial reasoning and musical abilities.

    Scientists call functions that are dominated by one hemisphere of the brain lateralized. While the left hemisphere of the brain is specialized for functions like language and mathematical thinking, the right hemisphere also works on these functions to a lesser degree. Scientists primarily determine where brain functions are localized and lateralized through a method called experimental ablation in which parts of the brain are selectively damaged when a function is hampered by damage to a specific area of the brain, it becomes evident that the function in question is performed by that area.
