What Percentage Of Our Brains Do We Actually Use Popular Myth Debunked In Ted
It’s commonly said that we humans use only about 10 percent of our brains, with some people attributing Einstein’s brilliance to his ability to stretch that paltry figure to 15 percent. But in the video above, neurologist Dr. Richard Cytowic debunks these familiar notions, arguing that brain regions once believed to be “silent” are actually humming with activity.
What exactly do these “silent” regions do? According to Cytowic, they’re intimately involved with our ability to plan, make decisions, adapt to evolving situations, and reason abstractly. And evidence suggests that at any moment up to 16 percent of our brain cells are active.
So next time your friends bring up the 10-percent nonsense, you’ll be able to set them 100-percent straight.
The 10 Percent Of The Brain Myth As It Is Called Has A Long History
And Lucy Director Luc Besson freely proclaims that his film is a fantasy based on little if any science.
The film certainly makes its own case that expanding activity beyond natural levels, let alone experiencing a 100 percent brain, comes with serious downsides, including what it portrays as increasingly ruthless behavior on the part of Johanssons character. As we will see, there are good neuroscientific reasons to stick with our natural allotment of activityand possibly to aim for less.
Yet many serious writers have used the film as a foil in order to debunk the 10 percent myth. They explain that, no, in fact, we use almost all of the brain, and we do so all the time. An eminent neurologist from Johns Hopkins School of Medicine was quoted in Scientific American as saying:
We Use 10 Percent Of Our Brain
A recent survey conducted by the Michael J. Fox Foundation revealed that 65 percent of survey respondents were under the impression that humans only use 10 percent of their brains. In reality, we use all of our brains to complete daily tasks like walking to work and breathing. Motor function, speech, and other utilities of the brain require every square inch of the cerebrum, cerebellum, frontal lobes, etc.

The Origin Of The Myth
The main allure of the 10 percent myth is the idea that you could do so much more if only you could unlock the rest of your brain. Even with ample evidence suggesting the contrary, why do many people still believe that humans only use 10 percent of their brains? Its unclear how the myth spread in the first place, but it has been popularized by self-help books, and may even also be grounded in older, flawed, neuroscience studies.
The myth could be aligned with messages espoused by self-improvement books, which show you ways to do better and live up to your “potential.” For example, the preface to the notorious “How to Win Friends and Influence People” says that the average person develops only 10 percent of his latent mental ability. This statement, which is traced back to psychologist William James, refers to a persons potential to achieve more rather than how much brain matter they used. Others have even said that Einstein explained his brilliance using the 10 percent myth, though these claims remain unfounded.
What Is The Memory Capacity Of A Human Brain
The human brains memory capacity in the average adult can store trillions of bytes of information. In a Stanford Study, it was reported that the cerebral cortex alone has 125 trillion synapses. In another study, it was reported that 1 synapse can store 4.7 bits of information. Neurons are the cells which processes and transmits messages within the brain, and synapses are the bridges between neurons which carry the transmitted messages. Running the numbers 125 trillion synapses 4.7 bits/synapse, and about 1 trillion bytes equaling 1 TB .
This storage capacity is an amount over 74 Terabytes
If you have a fairly new computer, tablet, or smartphone, you understand the phrase megabytes and gigabytes, this knowledge might help put your brains immense information storage capacity into perspective.
Early-generation personal computers had at best a few megabytes of hard-drive information storage capability. Thats a few million pieces of digital memory seemingly a lot at the time, but small by todays standards.
For instance, it is not uncommon for todays smart phones to have gigabytes of memory capacity or more.
By comparison, the IRSs own massive data warehouse, which keeps track of 300-plus million Americans and many more million businesses, has the capacity of 150 terabytes of memory. Yet Yahoos 2.0 petabyte computational center, which can process 24 billion events a day, is a full 20 percent smaller than the capacity of a single human brain.

One Of The Underlying Concepts In Your Book Is What You Call The Cerebral Mystique Can You Explain What It Means And Why This View Of The Brain Is Distorting Our Real Natures
This book is largely about two opposite ideas: the biological mind centered on the brain, in which influences from the rest of the body and outside the body shape what we think and do, and the cerebral mystique, a complex of stereotypes and ideals about the brain, which tend to treat it as an isolated and all-powerful entity, almost like a modern version of the soul.
The problem with having a dualistic view of the brain and its relationship to the physical body, and the physical world, is that it makes us see ourselves as unnaturally self-contained, both as minds and as autonomous agents. In other words, we view ourselves as things that operate from within, so were less sensitive to things that influence us on the outside. The idea that the brain is a machine, an abstract entity like a giant supercomputer, has been around for a while, basically since computers. Other people have used a quantum analogy for the brain. But the idea of the brain as a computer is the most common in this day and age.
No Secret Store Of Untapped Brain Power
It is true however that the brain never activates all its 86 billion brain cells at the same time but the balance between cells sending signals and cells currently remaining quiet is crucial for the brains ability to transmit information.
The uncontrolled mass activation of brain cells is called a seizure and constitutes a serious medical problem rather than functional enhancement.
It is also true that there is a certain degree of redundancy in the brains architecture where several pathways serve similar functions but this safety mechanism is an important part of what makes our brain so resilient and adaptable.
So, unfortunately, there is no secret store of untapped brain power. We use all of our brain.

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.
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.

Do We Use 100% Of Our Brain Or Its Just 10%
This has been a debate going around as to what exactly is the truth. Are we accessing only 10% of our brain or are we accessing 100% of our brain all the time? According to Barry Gordon, a neurologist of John Hopkins School of Medicine in Baltimore, the ten percent is only a myth and it is not true.
On the other hand, Sir John Eccles stated that the human brain has infinite potential. In addition, it was also stated that humans have unlimited capacity to learn unlike computers, no human brain has ever said: Hard drive full. The Doctors TV show covered this topic on February 10, 2015 and they are convinced that a human uses all of the brain all the time.
They even showed a brain scan courtesy of Washington University Show, indicating that every time we do something, there is a brain activity taking place in almost all areas. But what I have noticed is that they only focused on what the brain is doing with our body. In other sense, the brain activity that is seen in the scan in The Doctors show is the motor capacity of the brain that is a part of our body.
Sir John Eccless point is the humans mental capacity to access the gigantic network connections that we possess like what Freeman said in the movie. I dont think there is ever a machine that is able to measure something that is not seen and cannot be seen. It is mental. It goes beyond the physical aspect of the brain. It is psychology.
So Alabama Should Be More Violent Than Alaska
Right. All things being equal, the key to a good scientific study is that theres a good control. But comparing Alabama and Alaska may not be conclusive, as there are many differences. Throughout much of the year, people in Alaska probably see less light than people in Alabama, for instance. And the presence of colors and light levels in our environment can also have significant effects, both on the emotional aspects of personality and on cognitive functions.
Many of us are aware that not getting enough daylight can cause seasonal affective disorder, or SAD. Less familiar is the effect of colors. Even tiny color cues in your environment can affect your behavioral performance. It has been found, for instance, that blue-green-yellow type colors tend to be particularly arousing. Red, as its reputation suggests, tends to promote aggression and avoidance. In one study, researchers put little red or blue cues at the top of a fake exam, and found that the people who had the red cues on the exam did worse.

Keep The Brain Active
The more a person uses their brain, the better their mental functions become. For this reason, brain training exercises are a good way to maintain overall brain health.
A recent study conducted over 10 years found that people who used brain training exercises reduced the risk of dementia by 29 percent.
The most effective training focused on increasing the brains speed and ability to process complex information quickly.
There are a number of other popular myths about the brain. These are discussed and dispelled below.
Myths About The Human Brain: Do We Really Use Only 10% Of Our Brain
At the center of the central nervous system, protected by the bones of the skull, lies the brain. Commonly referred to as the bodys Command Center, the brain serves a variety of purposes that keep other organs functioning via billions of neurons and other cells. Due to the complexity of the bodys most valuable organ, there are several myths regarding the brain that have fooled most of us. So if you still believe that we only use 10 percent of our brain, listen up!

Why Some Humans Smarter Than Others
The next question that rapidly creeps our mind is that, if we all humans use the same amount of brain then how are some of them smarter than the remaining. This question raised the eyebrows of many scientists and soon an explanation was provided, smartness is related to cognitive plasticity which refers to the adaptive changes in patterns of cognition related to brain activity. The study of Einsteins brain proved that it contained the same number of neurons when compared to an average human beings brain. However, it did contain more astrocytes which also acts as a link between two neural cells. Now it is on the diversity of the neurons it contains that provides a reason for why some people are smarter.
They Looked At Mris Just To Be Sure
Unfortunately, just because you truly use more than 10 percent of your brain, does not mean you’re going to begin developing telekinesis.
Scientists have measured how much brainpower people use when doing certain activities. Healthline noted researchers look at brain activity through a magnetic resonance imaging . They ask people inside an MRI to look at photos or do certain exercises, and they study which parts of the brain light up when performing those functions. There’s even an episode of MythBusters where they tested the 10 percent myth. The MythBusters team asked people to accomplish complicated mental tasks word associations, memory drills, calculations and found that people use at least 35 percent of their brains to perform those activities.
What scientists can generally agree on is that we don’t yet fully understand the full brain. Scientific American said researchers continue to study the different parts of the brain to figure out the function of each. Generally, we know about neurons, but what about the glial cells that support neurons? What are their function? Nor do scientists know where consciousness comes from. We know that people use far more than 10 percent of their full brain capacity, but scientists are also still trying to understand more about how the brain works and what its full potential can be. In the meantime sorry. You really can’t make yourself read minds.

Is It Possible For A Human Brain To Defeat Supercomputers
When it comes to technology no one can ignore one of the most important invention, computers. For decades computer scientists have strived to build machines that can calculate faster than the human brain and store more information, however, they were able to pose no match to the human brain. In the last decade though in this race between the human brain capacity vs computers the latter was able to mark a win. The worlds most powerful supercomputer, the K from Fujitsu, computes four times faster and holds 10 times as much data as the human brain. The humans brain capacity is around 3.5 quadrillion bytes while this supercomputer was able to store around 30 quadrillion bytes.
Well learning these facts we all are able to relate that how powerful the human mind is. So we should always try and improve brain health by solving brain teaser questions or maintaining proper health. This way we all will also be able to think of new constructive ways to do goods to the society and help and make this world a better place to live in.
Why People Believe We Only Use 10% Of Our Brain
Researchers suggest that this popular urban legend has existed since at least the early 1900s. It may have been influenced by people misunderstanding or misinterpreting neurological research. The 10% myth may have emerged from the writings of psychologist and philosopher William James. In his 1908 book, The Energies of Men, he wrote, “We are making use of only a small part of our possible mental and physical resources.”
The myth has perpetuated much like other urban legends. Movies depict characters capable of remarkable feats when the supposedly unused 90% of their brains are “unlocked.” Well-intentioned people such as motivational speakers or teachers often cite the 10% myth as a way to demonstrate that all people should strive to live up to their full potential. Unfortunately, less well-meaning people have also used the myth to promote and sell products and services that they claim will unlock your brain’s hidden abilities.
