All You Need To Know About The 10 Percent Brain Myth In 60 Seconds

What percentage of your brain do you use? – Richard E. Cytowic

The new Luc Besson movie Lucy, starring Scarlett Johansson, opens tomorrow in theaters countrywide. It’s based on the immortal myth that we use only 10 percent of our brains. Johansson’s character is implanted with drugs that allow her to access 100 percent of her brain capacity. She subsequently gains the ability to learn Chinese in an instant, beat up bad guys, and throw cars with her mind . Morgan Freeman plays neuroscientist Professor Norman, who’s built his career around the 10 percent claim. “It is estimated most human beings use only 10 percent of the brain’s capacity,” he says, “Imagine if we could access 100 percent.”

As it happens, I’ve written a book all about brain myths . I thought I’d use what I learned to give you a 60-second explainer on the 10 percent myth.

Great Myths of the Brain, by Christian Jarrett, was published in 2014. .

No, the 2011 movie Limitless, starring Bradley Cooper was based on the same idea, except the precise figure was placed at 20 percent. Cooper’s character takes a pill that lets him access the full 100 percent. Both the 1991 film Defending Your Life and Flight of the Navigator include claims that most of us use a fraction of our brains. The myth is also invoked in the TV series Heroes, to explain why some people have special powers.


Brains Control Of Glycemia

In humans, the value for normoglycemia is around 1 g/l. Although the endocrine pancreas is the main regulator of blood glucose level via the secretion of insulin and glucagon, the brain plays a major role in controlling glycemia. This is achieved through different pathways involving the autonomic nervous system and its projection to several organs and tissues such as the endocrine pancreas, the adrenal gland, the liver, skeletal muscles, and white and brown adipose tissues. As illustrated in Figure 2, in case of a drop in blood glucose, there is an activation of sympathetic nerves and consequently an increase in glucagon secretion by the alpha cells and a decrease in that of insulin by the beta cells of the pancreas, as well as an increase in epinephrine and cortisol secretion by the adrenal gland. These changes in hormone levels together with a direct effect of the sympathetic system will lead to an increased glucose production by the liver, and a decreased glucose utilization by fat deposits and muscles, leading thus to a normalization of blood glucose.

The Impact Of Other Sugars On The Brain: The Example Of Fructose

The patterns of sugar consumption have changed considerably in recent decades. Glucose is not the only monosaccharide present in our alimentation, which can cross the intestinal barrier and be present in the bloodstream. Fructose is the other main monosaccharide we eat. Fructose is the partner of glucose in the sucrose we consume. In addition to its natural presence in fruit and honey, it is also present in soda, biscuits, and all sorts of processed food. Thus, while fructose consumption was < 5 g/day until the 70s, it consumption has dramatically increased since and currently reaches 5080 g/day in developed countries. In addition, the ending of European sugar quota in 2017 will likely further increase by 815% its intake in the next decade.

Debunking The 10% Myth

You may have heard that humans only use 10 percent of their brain power, and that if you could unlock the rest of your brainpower, you could do so much more. You could become a super genius, or acquire psychic powers like mind reading and telekinesis. However, there is a powerful body of evidence debunking the 10 percent myth. Scientists have consistently shown that humans use their entire brain throughout each day.

Despite the evidence, the 10 percent myth has inspired many references in the cultural imagination. Films like “Limitless” and “Lucy” depict protagonists who develop godlike powers thanks to drugs that unleash the previously inaccessible 90 percent of the brain. A 2013 study showed that about 65 percent of Americans believe the trope, and a 1998 study showed that a full third of psychology majors, who focus on the workings of the brain, fell for it.

Lucy Is Wrong We Use Way More Than 10% Of Our Brains

How much of Human Brain do we actually use? How to use 100 ...

I know I haven’t earned my Ph.D. yet, Professor, but I beg to differ. You see, we all access 100% of our brains every day. And we don’t have to be telekinetic or memorize an entire deck of cards to do it.

In the film, which opens next Friday, Scarlett Johansson’s character Lucy is forced to work as a drug smuggler in a Taiwanese mob. The drug they’ve implanted into her body leaks into her system, allowing her to “access 100%” of her brain. Among other things, Lucy can move objects with her mind, choose not to feel pain, and memorize copious amounts of information.

In a way, the idea that we only use 10% of our brains is rather inspiring. It may motivate us to try harder or tap into some mysterious, intact reservoir of creativity and potential. There are even products that promise to unlock that other 90%.

As ludicrous as the claim is, however, 2/3 of the public and half of science teachers still believe the myth to be true. The notion is so widespread that when University College London neuroscientist Sophie Scott attended a first aid course, her instructor assured the class that head injuries weren’t dangerous because “90% of the brain do anything.”

You may have played God in a movie, Morgan Freeman, but clearly you need a primer on how your most incredible creation-the brain-functions!

How To Unlock Your Full Brain Hidden Potential

Technically speaking it is not possible to use 100% of our brain for a single activity. But there is a fact that the way we increase our strength by muscular training similarly there are ways we can unlock or just use a higher percentage of our brains. The capabilities of your brain can be expanded by maintaining your health and challenging yourself to new things. Certain steps to try unlock a larger part of your brains are :

  • Stimulate your brain: Spending some time with nature, this helps you stimulate your brain and even improves cognitive function.
  • Try hard things: Scientists have found out that engaging your brain in some particularly hard and rigorous games or read a hard book which provides some new vocabulary as this helps you improve your fluid intelligence.
  • Try new things: As soon as you master at one task you should start the one, the reason being simple i.e. once your brain becomes efficient it stops trying new possibilities for a problem, so you should always be trying new things.
  • Take naps: It has been found out that small naps can boost your cognition, which helps you improve your brain function.
  • Healthy Routine: A healthy balanced diet, full nights sleep, avoiding the use of tobacco these are also certain factors which help in increasing the power of the brain.

Lucy Uses 100 Percent Of Her Brain But Is It Possible

Lucy makes a superhuman of Scarlett Johansson. But will technology advances ever help us better use our brains?

We upload our lives to the cloud, Google pours it into the Knowledge Graph to feed the algorithm, applies natural language parsing, and the Singularity, that moment when digital devices become more intelligent than humans, draws close.

But is the real story that machines and humans are meeting in the middle? Are we evolving to become plugged into the great digital cortex to become hybrid- humanoids? It’s a subject that’s fascinated Luc Besson, director of the new movie Lucy, for over a decade, and his film is astonishing.

Besson spent time with world-renowned neurologist Yves Agid, who co-founded the Brain & Spine Institute in Paris, to learn how cells communicate with each other and what cerebral capacity could be unleashed if the human brain’s 86 billion densely packed neurons fired at once.

Lucy starts off as just another flaky student hanging out in Taiwan, going to dodgy discos with men who wear cowboy hats and tinted sunglasses. Within minutes, the story turns into a thriller. She’s forced to become a drug mule, something goes horribly wrong , and then suddenly we’re in the realm of sci-fi with stunning FX.

Besson goes mystic as Lucy’s brain expands. She feels trees “grow,” senses peoples’ thoughts, and accesses their memory banks. We move, briefly, into the Buddhist realm of meditating monks who control their metabolism and experience infinite space.

Glucose: The Fuel Of Brains Neurons

Brain function and glucose metabolism are intimately linked . Indeed, glucose is the main, if not the only, energy substrate of this organ. Hypoglycemia causes rapid brain repercussions, but fortunately, most of the time quickly reversible after correction of hypoglycemia. With regard to hyperglycemia, acute situations such as ketoacidosis and hyperosmolarity can lead to a coma, with significant mortality. The chronic effects of hyperglycemia on the brain remain unclear, apart from the risk of ischemic stroke. However, microangiopathy is intimately linked to chronic hyperglycemia, and can cause irreversible diffuse vascular lesions and cerebral ischemia, resulting in cortical atrophy and diabetic encephalopathy.

The brain uses glucose as its main source of energy, although it can utilize other metabolites in special situations such as fasting. It has very high energy consumption for its size, mainly due to the high energy supply needed to maintain its functions .

What Would Happen If We Could Use 100 Percent Of Our Brain

What If You Used 100% Of Your Brain At The Same Time?

This question originally appeared on Quora. Answer by Yohan John, PhD in Cognitive and Neural Systems.

The idea that we only use 10 percent of our brains is a pernicious myth. The brain is always active. It makes a bit more sense to say that we use 100 percent of the brain all the time, but even this is misleading. Both the 10 percent or 100 percent estimates are not even wrong.

Brain function depends on qualitatively different patterns of activity, rather than quantities of activity. These patterns change depending on what you are doing, so some neurons or groups of neurons become active when others become inactive. Activating all neurons world be like pushing the break and the accelerator of a car at the same time – not a very good idea.

It can actually be dangerous if too many excitatory neurons become active simultaneously. Hyperactivity of groups of neurons is associated with epilepsy and other neurological disorders. When people say “you are only using a fraction of your brain” they are giving a pseudoscientific veneer to a piece of age-old folk knowledge: The perfectly reasonable idea that we are not realizing our full potential as people.

But improving our thoughts and behavior is not a matter of amplifying neural activity. Instead, it is about creating new and beneficial behavioral patterns, which correlate with altered neural activity patterns. So if you want to explore what else you are capable of just look around at people who have changed their habits.

You Already Use 100% Of Your Brain

Brain scans show activity coursing through your entire brain all the time, even at rest and during sleep. Not all 86 billion neurons are firing at once, of course, but they do exist in a constant state of resting potential, electrically charged, ready to act when needed.

An article in Scientific American, Do People Only Use 10% Of Their Brains, explains:

Evidence would show over a day you use 100 percent of the brain, says John Henley, a neurologist at the Mayo Clinic in Rochester, Minn. Even in sleep, areas such as the frontal cortex, which controls things like higher level thinking and self-awareness, or the somatosensory areas, which help people sense their surroundings, are active, Henley explains. .’t turns out though, that we use virtually every part of the brain, and that the brain is active almost all the time’

Action Potentials Of Neurons

Action potentials are the electrical impulses that travel through a neuron so that information can be transmitted to the next neuron. Action potentials only fire when there is enough stimulus to reach a threshold. It works in an all or none fashion, meaning that if it doesnt reach the threshold, the action potential wont fire. This is helpful because it ensures that all of our neurons arent firing at the same time- that would just be too much activity for the brain! But even when neurons are at rest, theyre still receiving information from other neurons. So essentially, the neurons are never inactive.

Why Don’t We Use %100 Capacity Of Our Brain

As far as know einstein is the most intelligent man was able to use his brain capacity of %4 or 7 .

I think this percent of usage is not satisfactory.

Why don’t we use the remain capacity of our brain?.

Is it possible to use the remain capacity? If yes how?

  • Answer #1

    ok. I’m going to try and bridge the confusion here. this is to the best of MY knowledge but like every one I make mistakes. however I am studying to be am MRI technician so I have had to study this. anyway. you are able to use 100% of your brain. however at any given time you use less then 10%. all parts are used, just not at once. so in fact both of the sides above are correct. there are no “secret” or “locked” parts. but our metabolism cam only support so much activity. a computer is always a good analogy for the brain. If you over-clock you comp but don’t upgrade your cooling system what happens? it melts. now your brain wouldn’t actually melt but you would, with a human metabolism, die, painfully. This is coming from a med student but I know full well I can make mistakes thou I believe myself to be right in this case as it does concern my specialty.hope I helped.

  • What Does It Mean To Use Only 10% Of Your Brain

    Do we really use 10% or 100% of our Brain?

    What data were used to come up with the number – 10%? Does this mean that you would be just fine if 90% of your brain was removed? If the average human brain weighs 1,400 grams and 90% of it was removed, that would leave 140 grams of brain tissue. That’s about the size of a sheep’s brain. It is well known that damage to a relatively small area of the brain, such as that caused by a stroke, may cause devastating disabilities. Certain neurological disorders, such as Parkinson’s Disease, also affect only specific areas of the brain. The damage caused by these conditions is far less than damage to 90% of the brain.

    Is There Such A Thing As Being Left

    Well, your brain definitely has a left side and a right side . Each hemisphere controls certain functions and movement on the opposite side of your body.

    Beyond that, the left brain is more verbal. Its analytical and orderly. It takes in the small details, and then puts them together to understand the whole picture. The left brain handles reading, writing, and calculations. Some call it the logical side of the brain.

    The right brain is more visual and deals in images more than words. It processes information in an intuitive and simultaneous manner. It takes in the big picture, and then looks at the details. Some say its the creative, artsy side of the brain.

    Theres a popular theory that people can be divided into left-brained or right-brained personalities based on one side being dominant. Left-brained people are said to be more logical, and right-brained people are said to be more creative.

    After a two-year analysis , a team of neuroscientists found no evidence to prove this theory. Brain scans showed that humans dont favor one hemisphere over the other. Its not likely that the network on one side of your brain is substantially stronger than the opposite side.

    As with most things relating to the human brain, its complicated. While each hemisphere has its strengths, they dont work in isolation. Both sides contribute something to logical and creative thinking.

    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.
