Left Brain Right Brain Dominance Tied To Ear Preference In Cell Phone Users

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

When it comes to using your cellphone, are you a righty or a lefty?

A provocative new study from Henry Ford Hospital in Detroit suggests that the brains of cellphone users show subtle differences based on which ear users typically use to listen to their phones: people who tend to listen using the right ear usually have brains in which the left hemisphere dominatesand vice versa.

In general, the brain’s left hemisphere seems to specialize in processing language and producing speech, carrying out sequential processing of information, focusing attention, and inhibiting negative emotions, according to the website of the Dana Foundation, a brain research organization. In contrast, the right hemisphere seems to specialize in simultaneous processing of information, attending in a broad or diffuse way, forming and using spatial maps, and expressing intense emotions.

What does that mean in simple English? There’s some evidence that so-called “left-brain-dominant” people are more analytical while “right-brain-dominant” people are more creative, study author Dr. Michael Seidman, director of the hospital’s division of otologic and neurologic surgery, told The Huffington Post in an email.

So does that mean you can make inferences about your intellectual and emotional tendencies by noting whether youre right- or left-eared when it comes to cellphone use? And can noting others cellphone use habits enable you to gauge their intellectual and emotional tendencies?

The Architecture Of The Brain

The brain is like a committee of experts. All the parts of the brain work together, but each part has its own special properties. The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain.

The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum . The hindbrain controls the bodys vital functions such as respiration and heart rate. The cerebellum coordinates movement and is involved in learned rote movements. When you play the piano or hit a tennis ball you are activating the cerebellum. The uppermost part of the brainstem is the midbrain, which controls some reflex actions and is part of the circuit involved in the control of eye movements and other voluntary movements. The forebrain is the largest and most highly developed part of the human brain: it consists primarily of the cerebrum and the structures hidden beneath it .

When people see pictures of the brain it is usually the cerebrum that they notice. The cerebrum sits at the topmost part of the brain and is the source of intellectual activities. It holds your memories, allows you to plan, enables you to imagine and think. It allows you to recognize friends, read books, and play games.

Ventricles And Cerebrospinal Fluid

Deep in the brain are four open areas with passageways between them. They also open into the central spinal canal and the area beneath arachnoid layer of the meninges.

The ventricles manufacture cerebrospinal fluid, or CSF, a watery fluid that circulates in and around the ventricles and the spinal cord, and between the meninges. CSF surrounds and cushions the spinal cord and brain, washes out waste and impurities, and delivers nutrients.

Which Is True About The Theory Of Hemispheric Dominance

Hemispheric dominance or left-brain versus right-brain dominance is the theory that one side of the brain dominates your thinking. The rationale behind it is that the two sides of the brain process information differently, we tend to prefer one type of thinking over the other and hence one side will dominate.

Left Brain vs. Right Brain: The Surprising Truth

Follow me on Twitter @RobShmerling

If youre like me, you learned that about 90% of people are right-handed and much of the reason is genetic. And thats true, although it remains a mystery why our genetic evolution led to so many more righties than lefties.

But for certain tasks, handedness can be “overcome.” For example, right-handed kids learning to play tennis, golf, or baseball can become successful hitting from “the other side.” It may be more a matter of how they are taught and what gets reinforced than about a hard-wired preference for one hand or the other.

According to recent research, the idea of people being “left-brained” or “right-brained” may also be less fixed than wed thought.

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.

Damage To The Left Brain

Damage to either side of brain can lead to adverse effects on the individuals body. Considering that the right part of the body is commanded by left brain, any damage caused to it shows in the form of adverse effects on the right side of the body. Nervous system and immune system are related to each other and hence, any damage caused to either of them, reflects on the other parts of human anatomy. Even studies stress on the basic fact that left hemisphere brain damage can lead to immunological disorder in right-handed individual. Besides this, the person is also known to experience difficulty with various functions attributed to this side of the brain, including speaking, writing, memorizing, and analyzing.

All these functions and characteristic traits of the left brain help people excel in fields requiring analytical skills. These include law, accounting, engineering, etc.

Some Key Neurotransmitters At Work

Do People Really Have Right or Left Brain Personalities?

Neurotransmitters are chemicals that brain cells use to talk to each other. Some neurotransmitters make cells more active while others block or dampen a cell’s activity .

Acetylcholine is an excitatory neurotransmitter because it generally makes cells more excitable. It governs muscle contractions and causes glands to secrete hormones. Alzheimers disease, which initially affects memory formation, is associated with a shortage of acetylcholine.

Glutamate is a major excitatory neurotransmitter. Too much glutamate can kill or damage neurons and has been linked to disorders including Parkinson’s disease, stroke, seizures, and increased sensitivity to pain.

GABA is an inhibitory neurotransmitter that helps control muscle activity and is an important part of the visual system. Drugs that increase GABA levels in the brain are used to treat epileptic seizures and tremors in patients with Huntingtons disease.

Serotonin is a neurotransmitter that constricts blood vessels and brings on sleep. It is also involved in temperature regulation. Low levels of serotonin may cause sleep problems and depression, while too much serotonin can lead to seizures.

Dopamine is an inhibitory neurotransmitter involved in mood and the control of complex movements. The loss of dopamine activity in some portions of the brain leads to the muscular rigidity of Parkinsons disease. Many medications used to treat behavioral disorders work by modifying the action of dopamine in the brain.

The brain is the vital organ of the central nervous system. It is a complex organ consist of billions of interconnected neurons and glia. The brain has two sides and separated into unique lobes. Each lobe has a specific set of functions.

Although the brain is a complex organ a hardworking one with a hundred billion neurons, it surprisingly weighs only three pounds. It makes up around 2% of the human weight and only takes up about 20% of the bodys total energy.

The brain, being an intricate organ, performs a lot of functions. The two sides of the brain communicate with one another to perform all vital bodily processes. Both the left and the right side of the brain look very much alike but they too share some differences, especially in processing information.

Lack of integration between the different components of the brain could result in some forms of impairment.

The human brain has the ability to recognize itself. It has the ability to learn and adapt to change. Each side of the brain has a distinct function, which affects the persons ability to learn and adapt.

What Is The Personality Of A Left

Left-brained people prefer cold-hard facts and real-life data rather than emotions and imagination. Their systematic and stable personalities make them good candidates as reliable team leaders. They often pace themselves and do not overreact quickly.

When it comes to daily life, left-brain personalities approach it the same way they approach their professional or academic obligations. They strive to be as clear and direct as possible. Left-brain people like order and organize their daily plans as neatly and systematically as possible.

They remember events chronologically, usually in great detail, and approach every potential risk with necessary caution. When facing problems, they immediately try to find the most efficient solutions, and they are not easily distracted by their emotions.

An example of a left-brained is when they watch a movie, they analyze it from a technical point of view. They evaluate the quality of a script as well as how good or bad the directing is.

The Two Halves Of The Brain

The human brain is the body’s control centre that processes our bodily sensations, emotions and perceptions. It is also believed to be responsible for moulding our personalities, talents and skills. Every single person has a right brain and a left brain. The two different sides of the brain control two different types of thinking. The right brain is the “creative” side while the left brain is the “logical” side.

Research reveals that most people prefer only one style of thinking over the other. Some people are naturally more creative or right-brained, while others are more logical, making them left-brained. Ironically, the right side of the brain controls the muscles on the left side of the body, while the left hemisphere controls the motor skills of the right side of the body. That means, left-handed people have a stronger right hemisphere, while right-handed people have a more dominant left brain.

There is a fold that goes from the front to the back of the brain, essentially dividing it into two different parts. The “corpus callosum” is a thick bundle of nerves at the base of the brain connecting the two different parts. Additionally, it wires the right side of the body to the left side of the brain and vice versa. This crossover is applicable to all areas of the body, including the eyes, which process a majority of their sensory data on the opposites of the brain.

What Are Some Characteristics Of The Left Side Of The Brain

What Does the Left Side of the Brain Control?

People are often categorized either as left-brained and right-brained, meaning one side of their brain is dominant.

In this article, we will explore specifically the left brain characteristics, what they are, what it means to be a left-brain person, and how you can align your left brain using your knowledge, skills, and talents to reach your brains full potential.

What Is The Gray Matter And White Matter

Gray and white matter are two different regions of the central nervous system. In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: The white matter is on the outside, and the gray matter sits within.

Gray matter is primarily composed of neuron somas , and white matter is mostly made of axons wrapped in myelin . The different composition of neuron parts is why the two appear as separate shades on certain scans.

Each region serves a different role. Gray matter is primarily responsible for processing and interpreting information, while white matter transmits that information to other parts of the nervous system.

Who Is Likely To Have A Stroke

Anybody can have a stroke, but your risk increases with age. A family history of stroke or mini-stroke, also called a transient ischemic attack, increases your risk. People over age 65 account for two-thirds of all strokes.

Males and people of African-American, Hispanic, Asian, or Pacific Islander descent are also at higher risk. However, women are more likely to die from stroke than men.

Other conditions that increase your risk of stroke include:

Mixing Fact With Fiction

Its true each hemisphere of the brain controls different functions, but this fact doesnt relate to personality. The misleading idea of left vs. right brained people originates from science and has become fictionalized over time.

Take TheStrange Case of Dr. Jekyll and Mr. Hyde, for example. Robert Louis Stevensons fictional characters represented the duality of human nature and explored the idea of a logical left brain competing with an emotional right brain .

People love to learn about their own psychology, and they crave definitive answers. We love classification schemes like astrology, Myers-Briggs and endless personality quizzes, even though, according to Inc., calling yourself left brained or right brained is totally meaningless.

What Happens If You Damage Your Left Temporal Lobe

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

Since the temporal lobe processes emotions and plays an important role in short-term memory, damage to this area of the brain can result in unique symptoms.

Damage to the left temporal lobe mainly results in abnormal changes to emotions, such as sudden feelings of fear, euphoria, or episodes of deja vu.

The official name for these distressing feelings is focal seizures with impaired awareness. The bigger the seizure, the less responsive a person becomes.

During such an episode, the person may be aware of whats happening around them but may be unable to respond. They may also move their lips and hands repetitively.

These conditions are mostly treated and controlled with medications. In case medications fail to solve this, surgery is an option.

If an egg is broken by an outside force, life ends.If broken by an inside force, life begins.Great things always begin from the inside.

Basic Temporal Lobe Function

The temporal lobes are located at the sides of the brain, and can be considered the “middle” region of each brain hemisphere. As a whole, the temporal lobe is the part of your brain in charge of memory storage, the process of hearing sounds, visual recognition of faces and objects, and the use of language. Though this seems like an incredible number of functions for one small part of the brain to command, the temporal lobes are actually more complex than they look they contain a number of specialized substructures, including the amygdala and auditory cortex, that perform a variety of high-level functions. At the same time, the temporal lobes aren’t the only parts of the brain used in many of these mental processes the frontal and parietal lobes make sense of processed sounds for example, and the hippocampus creates the memories that the temporal lobe then stores and recalls.

What If My Brain Injury Or Stroke Is On The Right Side Of My Brain

Injury to the right side of the brain may result in left sided weakness and the following cognitive and communication problems:

  • Attention: Difficulty concentrating on a task or focusing on what is said or seen.
  • Left neglect: Problems with attending to things on the left side
  • Visual perception: Visual perception deficits including processing any information on the left visual field
  • Reasoning and problem solving: Difficulty identifying that there is a problem and generating solutions
  • Memory: Difficulty recalling previously learned information and learning new information.
  • Social communication: Difficulty interpreting abstract language such as metaphors, making inferences, understanding jokes, and nonverbal cues.
  • Organization: Difficulty with arranging information and planning, which is often reflected in communication difficulties, such as trouble telling a story with events in the right order, giving directions, or maintaining a topic during conversation.
  • Insight: Difficulty recognizing problems and their impact on daily functioning.
  • Orientation: Difficulty recalling the date, time, or place.
