Left Brain Vs Right Brain: Which Side Is More Creative

Why does one side of the brain control the other side of the body?

Humansmore so than any other specieshave transcended the baseline goals of survival, allowing for the blossoming of complex societies, innovative technologies and philosophical theorizations. But what makes humansopposed to their closest primate relativesso well equipped for creative advancements? The answer lies above the shoulders, inside the protective bone casing and within the bumpy contours and careful folds of the human brain.

As neurologists continue studying this mystical organ, previously held neurological truths are revised and updated. Scientists know that the brain is divided into left and right hemispheres. It was previously thought that the left brian controls logic and reasoning while the right brain controls emotions and creativity.

This juxtaposition was thought to be present in peoples personalities: with more artistic people having a dominant right brain, and more analytical people having a dominant left brain. Though it may seem logical, this line of reasoning is not supported by neurologists, who cite this myth as perpetuating the fallacy of localized creativity and dominant brain hemispheres.

Lets take a deeper look into how the left brain vs right brain myth started and what neurologists now know about specialization of the hemispheres.

The Truth About The Left Brain / Right Brain Relationship

    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?

    Right Hemisphere Brain Damage Treatment

    Working with a diverse team of rehabilitation specialists can help ensure that all the secondary effects of right hemisphere brain damage are addressed.

    Some common rehabilitation therapies used to treat right hemisphere brain injuries include:

    • Physical therapy. To restore movement and strength, your best option is to practice physical therapy exercises that utilize your affected muscles. A PT will guide you through targeted exercises to stimulate the muscles and strengthen connections to the brain.
    • Occupational therapy. Due to executive functioning problems or muscle weakness, basic tasks such as getting dressed and using the bathroom may become very challenging. An occupational therapist can help you develop your independence by teaching you new ways to perform everyday activities.
    • Cognitive exercises. Practicing memory games and other cognitive exercises can stimulate the brain and improve cognitive functioning.
    • Speech therapy. If you experience social deficits or issues involving musicality of speech, a speech-language pathologist can help teach you techniques to become a more effective communicator.
    • Psychotherapy. A psychotherapist can help individuals address their emotional problems after TBI and suggest more effective ways to cope.

    Right hemisphere damage can cause a variety of problems. But if you persevere with your therapy, it is possible to regain the skills and abilities youve lost even years after injury.

    Injury In The Left Hemisphere Of The Brain

    Since the left hemisphere of the brain controls the right side of the body, any injuries in it could lead to right-sided weakness. The following problems could arise:

    • Difficulty understanding both written and spoken words.
    • Difficulty expressing both written and spoken words.
    • The person finds it difficult to coordinate or program motor movements for speaking or medically called apraxia.
    • Slurred speech or change in the sound of the voice .
    • Difficulties with numbers.
    • Difficulty in dealing with complex problems.

    Everything You Need To Know About Right Brain Characteristics

    Your brain is divided into the left cerebral hemisphere and the right cerebral hemisphere. Find out more about common right-brain characteristics.

    The brain is one of the most important organs in our body. In fact, many would argue that it is the most important part as it controls every function of the body. It also helps us process information and makes sense of the world around us.

    The brain has the left and the right hemispheres which control different functions. Researchers have studied hemispheres extensively to understand what are the functions of each of them. Right brain characteristics are under the most scrutiny because it deals with components of human that are lesser-known: our emotions and creativity.

    In this article, we will focus on right-brain characteristics. Well explore what it means to be a right-brained person. And more importantly, how you can improve the right side of your brain for knowledge, skills, and talents.

    Crossing The Nerve Pathways: Pyramidal Decussation

    To begin the explanation, we have to resort to the concept of decussation or chiasma .

    We call pyramidal decussation the crossing made by the pyramidal fibers, passing the nerve fibers from the left side of the brain to the right half body and those from the right side to the left.

    This therefore implies that the part of the brain that controls our right part is the left hemisphere, being the lesion of the left hemisphere the one that could cause paralysis and other conditions on the right side of the body.

    However, despite the fact that most nerve fibers cross the contralateral hemibody, between 15 and 20% of nerve fibers do not pass through decussation, continuing to function ipsilaterally .

    From this decussation, two large bundles of neurons emerge, the anterior corticospinal and the lateral corticospinal . The lateral corticospinal is associated with the fine movement of the most distal parts of the body, such as the fingers, allowing skills such as writing or manipulating objects.

    The ventral or anterior, although it does not decline in the pyramidal decussation of the medulla oblongata, largely ends up doing so within the spinal cord itself, reducing the percentage of fibers that remain ipsilateral to around 2%. It takes care of the proximal areas of the extremities, trunk and neck.

    How Is Being Right

    The left brain vs. right brain myth – Elizabeth Waters

    Each brain hemisphere controls the movement of the opposite side of the body. In left-handed people, the motor cortex in the right hemisphere is dominant for fine motor behaviors, such as writing with a pencil. The reverse is true for right-handed peoplethe left hemisphere is stronger when it comes to such movements.

    There Are Differences Between The Hemispheres Though Right

    Yes.

    You might not have a more dominant half, but your brain really is split into two hemispheres, left and right.

    And the left and right hemispheres are not the same. They are highly similar and redundant, though. Most processes that you’d find on the left side also take place on the right, and vice-versa.

    The book “Disorders of the Nervous System: A Primer” by Dartmouth neurologists Dr. Alexander Reeves and Dr. Rand Swenson, quotes Dr. Harold Wolff one of the great brain scientists of the 20th century as saying that both sides of the brain have “the capacity to express appropriate feelings, appetites and drives the capacity learning, memory, logic, etc. the capacity to maintain appropriate thresholds and tolerance for frustration and failure, and to recover promptly from their effects the capacity to maintain effective and well-modulated defense reactions .”

    That’s some dense text, but the point is simple: Just about everything about your brain that makes you human exists on both sides of the organ.

    Need proof? If you remove a hemisphere from the brain of a 3-month-old baby a surgery that doctors sometimes perform in cases of severe epilepsy and other disorders, according to the Cleveland Clinic that baby can still grow up with normal memories and a normal personality. Surgeons pulled off the surgery, known as a hemispherectomy, “hundreds of times” in the last century, according to Scientific American.

    So, what’s the difference between the two hemispheres?

    Right Hemisphere Brain Damage: What To Expect And How To Recover

    Elizabeth Denslow, OTR/L Flint Rehab

    Right hemisphere brain damage can affect a wide variety of motor, cognitive, and emotional functions. For example, it can cause difficulties with memory or paralysis on the left side of the body. Being aware of the potential effects of right hemisphere brain damage can help you quickly identify complications and seek treatment to improve your quality of life.

    To help you better understand and cope with right hemisphere brain damage, this article will discuss:

    • Facial recognition
    • Musical ability

    Additionally, the right side of the brain controls movement and perception on the opposite side of the body. Therefore, the ability to move the left side of your body and process visual stimuli on the left side is all attributed to the right hemisphere of the brain.

    When the right hemisphere of the brain sustains damage, individuals may experience various secondary effects that lead to difficulties performing tasks that require these functions. Up next, well discuss 10 potential effects of right hemisphere brain damage.

    But Why Would The Body Indulge Itself By Crossing Certain Nerve Pathways

    As always, nature does not indulge itself, and the explanation must be found in terms of evolution and Natural Selection, that is, survival. And since it is about survival, we must talk about the flight responses and the speed to execute them, in addition to the sense through which we essentially detect dangers: sight.

    It is well known that our eyes, due to optical issues, invert the image and thus project it onto the retina.

    Part of the nerves that collect this visual information, since ours is binocular must decuse so that the visual cortex of both hemispheres collect a real image of the physical environment.

    Thus, the right fibers of our eyes collect information from the left region of the total visual field, and the left fibers collect information from the right region of the visual field. The right visual cortex ends up processing the left information from the visual field thanks to these decisions, and vice versa.

    And what does that have to do with motor response? As we have said, the design of our body has been shaped by a vital and constant need to be as effective as possible. That opposite side motor control exerted by each hemisphere is an effective design.

    If this decussation of the motor pathways does not exist, of the cables that carry the information of move on!, The left visual cortex should send the information to the motor cortex of the right hemisphere to initiate the motor response of withdrawing the right arm.

    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.

    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 left-and-right-brain 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.

    Muscle Weakness And Left

    Each hemisphere of the brain controls movement on the opposite side of the body. Therefore, brain damage to the right hemisphere often leads to muscle weakness or paralysis on the left side of the body.

    In addition, right hemisphere brain injuries can cause problems with processing information in the left visual field, often called left-side neglect. A person with left-side neglect may not notice objects on their left side, as their brain is having trouble processing information from this side of their environment. They may also have trouble reading words on the left half of a page and even ignore food on the left side of their plate.

    There are various ways to work on managing and improving left-side neglect, including sitting on an individuals left side when talking with them and putting an ending point on the left edge of a page to encourage reading all the way across.

    Often, individuals with left-side neglect are unaware that they have a problem. This is related to another secondary effect of brain damage called anosognosia, which we will cover in more detail later on in this article.

    Insight And Organization Problems

    Right hemisphere brain damage may make it difficult to arrange information, which can cause problems with executive functioning skills such as organizing and planning basic tasks.

    Additionally, damage to the right hemisphere may lead to impaired judgment when it affects a persons insight or ability to understand the consequences of an action. Often, individuals with right hemisphere brain damage struggle with self-awareness, which can make it challenging to control their actions.

    Your Brain Is Divided Into Two Sides Called Hemispheres

    What’s the Difference Between the Right Brain and Left Brain?

    The right side of your brain controls the left side of your body, and the left side of your brain controls the right side of your body. Interesting, right? The two sides of your brain are similar to one another for example, the part of your brain that tells your arms and legs to move is the same on the right and left it just controls different sides of your body.

    Blood Supply To The Brain

    Two sets of blood vessels supply blood and oxygen to the brain: the vertebral arteries and the carotid arteries.

    The external carotid arteries extend up the sides of your neck, and are where you can feel your pulse when you touch the area with your fingertips. The internal carotid arteries branch into the skull and circulate blood to the front part of the brain.

    The vertebral arteries follow the spinal column into the skull, where they join together at the brainstem and form the basilar artery, which supplies blood to the rear portions of the brain.

    The circle of Willis, a loop of blood vessels near the bottom of the brain that connects major arteries, circulates blood from the front of the brain to the back and helps the arterial systems communicate with one another.
