Understanding Left Side Brain Injury

Why Your Left Brain Hemisphere Controls The Right Parts Of Your Body

The brain acts as the control center for the entire body and is responsible for both physical and cognitive abilities. It consists of two hemispheres, each of which governs the opposite side of the body. For example, the left hemisphere commands movement on the right side of the body, and vice versa.

For most individuals, the right side of the brain is responsible for non-verbal, intuitive and creative actions such as musical and artistic ability. The left hemisphere, on the other hand, is in charge of verbal, analytical and logical functions.

Some specific functions the left hemisphere controls include:

  • Logic and reasoning
  • Right-hand control
  • Sequential thinking

The left side is also considered the language hub of the brain. It is where the bulk of your language abilities lie, particularly your ability to produce and understand language.

Therefore, most people with left-side brain injuries have difficulty speaking, a condition known as aphasia.

Lets take a closer look at aphasia, and other effects of left hemisphere damage,

What Are The Functions Of The Left Temporal Lobe

The four lobes of the brain are responsible for organizing and assimilating all that we perceive.;The four lobes of the brain include the frontal lobe, the parietal lobe, the occipital lobe, and the temporal lobe. The temporal lobe is further divided into the right and left temporal lobes.

The primary function of this lobe of the brain is to control sight and sound processing. Its also responsible for language usage. The left temporal lobe is the reason were able to make sense of the words that we read and hear.

What Does The Left Frontal Lobe Control

The left side of the brain controls movement related to language, whereas the right side is responsible for nonverbal tasks. Collectively, the frontal lobes are the part of the brain that is home to our emotional regulation centers and controls our personality, for example.

The frontal lobes in general have a huge influence on many aspects of our intellect and behavior, evidenced by the diversity of symptoms that can occur when the area is damaged. The anatomy of the brain is well- defined, but scientists are still learning about its exact functions. Although the left side is more involved in language-based tasks for most people, this does not always have to be the case. Rarely, some young children require the removal of half their brain as a result of a medical condition. Despite this loss, the remaining half of the brain is sometimes able to pick up the slack and do everything the other half did before it was removed.

Lobes Of The Brain And What They Control

Each brain hemisphere has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions.

  • Frontal lobe. The largest lobe of the brain, located in the front of the head, the frontal lobe is involved in personality characteristics, decision-making and movement. Recognition of smell usually involves parts of the frontal lobe. The frontal lobe contains Brocas area, which is associated with speech ability.
  • Parietal lobe. The middle part of the brain, the parietal lobe helps a person identify objects and understand spatial relationships . The parietal lobe is also involved in interpreting pain and touch in the body. The parietal lobe houses Wernickes area, which helps the brain understand spoken language.
  • Occipital lobe. The occipital lobe is the back part of the brain that is involved with vision.
  • Temporal lobe. The sides of the brain, temporal lobes are involved in short-term memory, speech, musical rhythm and some degree of smell recognition.

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.

Where Is The Occipital Lobe Located

Understanding the occipital lobe requires a basic understanding of brain anatomy. The cerebral cortex of the braina part of the brain shared by all vertebratesis the newest part of the brain, evolutionarily speaking. All mammalian brains have four distinct lobes, but the brain itselfas well as the lobes it containsis divided into right and left hemispheres. This means that each lobe can actually be divided into two parts. The occipital lobe includes a right and left lobe that interact with one another, each controlling a range of visual functions.

Like other lobes of the brain, the occipital lobe does not have clear internal boundaries separating it from the rest of the brain. Instead, neuroscientists use the skull’s bones as their guide, so the occipital lobe rests underneath the occipital bone.

The occipital lobe is the rearmost lobe of the brain, located in the forebrain. It rests upon the tentorium cerebelli, a thick membrane of tissue the separates the cerebrum from the evolutionarily older cerebellum.

Left Brain Vs Right Brain

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

What Part Of The Brain Controls Fear

From a biological standpoint, fear is a very important emotion. It helps you respond appropriately to threatening situations that could harm you.

This response is generated by stimulation of the amygdala, followed by the hypothalamus. This is why some people with brain damage affecting their amygdala dont always respond appropriately to dangerous scenarios.

When the amygdala stimulates the hypothalamus, it initiates the fight-or-flight response. The hypothalamus sends signals to the adrenal glands to produce hormones, such as adrenaline and cortisol.

As these hormones enter the bloodstream, you might notice some physical changes, such as an increase in:

  • heart rate
  • blood sugar
  • perspiration

In addition to initiating the fight-or-flight response, the amygdala also plays a role in fear learning. This refers to the process by which you develop an association between certain situations and feelings of fear.

How Does The Occipital Lobe Interact With Other Areas Of The Body

No part of the brain is a standalone organ that can function without information from other parts of the body. The occipital lobe is no exception. Although its primary role is to control vision, damage to other brain regions and body parts can inhibit vision. Moreover, some evidence suggests that, when the occipital lobe is damaged, nearby brain regions may be able to compensate for some of its functions. The occipital lobe is heavily dependent on:

  • The eyes, particularly the retinas, which take in and process visual information to then be further processed by the occipital lobe.;
  • The frontal lobe, which contains the brain’s motor cortex. Without motor skills, the eyes cannot move or take in information from surrounding regions.;
  • The temporal lobe, which helps assign meaning to visual information, in addition to encoding it into memories.

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.

What Are Some Important Structures In The Occipital Lobe

Like all other lobes of the brain, the occipital lobe contains a number of structures and neuronal tracts that work together to enable vision. Those include:

  • Brodmann area 17: Known as V1, this region is located in the occipital lobe’s calcarine sulcus, and serves as the brain’s primary visual cortex. It aids the brain to determine location, spatial information, and color data.
  • The ventral stream: Known sometimes as V2, this is a secondary visual cortex that helps the brain assign meaning to what it is seeing. Without V2, you would still be able to see, but would have no conscious awareness of or understanding of the sights your eyes took in.
  • The dorsomedial stream: Neuroscientists don’t yet have a strong understanding of this brain region, which connects to both V1 and V2, as well as other brain regions.
  • The lateral geniculate bodies: These structures take in optic information from retinal sensors in each eye, sending raw information to each visual cortex.
  • Lingula: this area receives information from the contralateral inferior retina to gather information about the field of vision.

Brain imaging studies have revealed that neurons on the back of the gray matter of the occipital lobe create an ongoing visual map of data taken in by the retinas.

Common Questions About Right Brain Vs Left Brain

Q: What is the difference between the left brain and right brain?

Common theory suggests that the left brain is needed for more logic-based skills such as learning a language and mathematics, while the right brain is needed for creative tasks such as art, as well as connecting to others on an emotional level.

Q: What is a left-brain person like?

Supposedly, people whose left brain is more dominant tend to be more logical and better at science and mathematics than those who are more right-brain dominant.

Q: Is left brain and right brain a thing?

A commonly-held belief is that analytical people think more with the left side of their brain while artistic or intuitive people lean more heavily on the right side of their brain for support. In reality, though, the brain sends constant signals back and forth, and everyone is dependent on both sides of the brain.

Q: How much of my brain do I use?

There has long been a myth that people only use 10% of their brain. In fact, technology such as functional magnetic resonance imaging has revealed activity in the majority of the brain. Furthermore, damage to any part of the brain will impact a persons cognitive abilities, therefore disproving the myth that we only use a small section of our brain.

What Do The Parts Of The Brain Control

Do People Really Have Right or Left Brain Personalities?

Researchers study the parts of the brain and what each part does in order to understand where functions of the brain occur. Discoveries about brain anatomy assist medical professionals in diagnosing and treating brain disorders and tumors. There are three main divisions of the brain: the cerebrum, cerebellum and brain stem.

Left And Right Brain Roles

Tracking activity in the brains of healthy people while theyre engaging in different tasks, as we do with neuroimaging, provides another, more modern window into laterality. For example, neuroimaging studies suggest that the two hemispheres might play different roles in emotion processing, with the left hemisphere showing somewhat greater activation for happy or positive emotions and the right hemisphere showing more activity during negative emotional processing.

One particularly interesting insight that neuroimaging has given us is the finding that white matter tracts, or the wiring diagram of the two hemispheres, is different. The wiring of the right hemisphere has been called more efficient because it has greater connectivity between regions.

Think of a city with a really good subway system, like Manhattan, making it easy to get from one side of the city to another. The left hemisphere, in contrast, seems to be more modular. Its more like a cluster of little cities operating more independently, like Los Angeles, where every mini-city has its own municipal transport system and the cities themselves are not well connected. Santa Monica and Beverly Hills have different governing bodies, so its hard to get from one to the other using public transportation.

What Can Happen If Your Frontal Lobe Is Damaged

A famous case of frontal lobe damage is that of Phineas Gage. In 1848, Gage was injured in an explosion that caused a railroad spike to pierce his frontal lobe. The resulting injury caused drastic changes in Gages personality and behavior.

As weve learned, the frontal lobe is responsible for many different types of functions. Because of this, damage to the frontal lobe can cause a variety of different symptoms depending on the area thats affected.

Some potential symptoms of frontal lobe damage can include:

  • loss of movement, either partial or complete , on the opposite side of the body
  • difficulty performing tasks that require a sequence of movements
  • trouble with speech or language
  • poor planning or organization

Treatment for damage to the frontal lobe depends on whats caused the damage to occur. If you have frontal lobe damage, your treatment plan may include a team of several types of healthcare professionals.

Some examples of potential treatments for frontal lobe damage include:

In some cases, the cause of the frontal lobe damage may be permanent. One example of this is neurodegenerative diseases. In these cases, treatment may also involve medications.

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 Did The Myth Come From

Difference Between Left Brain and Right Brain

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 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.
