What Percent Of Your Brain Do You Really Use
Pretty sure youve heard that we humans only use 10 percent of our brains. You probably heard it from teachers or from movies. But, like many things school lied to you about, this is one fact that definitely doesnt stand up to actual science.
The truth is, while theres no known limit to what the brain can do, there are times when youre actually using 100 percent of your full brainpower. As explained by Scientific American, not all parts of the brain fire at once, but over the course of a day, a person wouldve used their full brainpower. Thats because the majority of what you do, no matter how mindless it may seem, requires far more from your brain than you think. Things like your morning coffee routine activate various parts of the brain in a matter of seconds. Getting up to get the coffeepot, pour it in a mug, and leaving extra room for cream fires up the occipital and parietal lobes, motor-sensory and sensory-motor cortices, the basal ganglia, cerebellum, and the frontal lobes, said Scientific American. If it takes that much brainpower to make coffee, imagine how much more is required by something truly complicated, like understanding a lesson in school or writing a report.
Scientists said its simply not fair to say 90 percent of your brain doesnt matter, because all parts of the brain work. Theres no filler.
Can We Really Change Our Own Brains
The more that neuroscientists study the brain, the more theyâre discovering just how much our brains can change.
âThrough neuroplasticity, our brain can change it can change in direct response to the way we live our life,â Rebecca says.
Neuroplasticity refers to the brains capacity to change, such as changes to the brainâs wiring, changes to the size of different brain regions, changes in how brain networks function, or the birth of new neurons. Critically, many of these changes can happen in response to our experiences or regular activities.
For example, a series of seminal research studies on what happens to the brains of people who learn to juggle found positive changes occurred in the size and connections of the brain involved in the activity.
âThat was a revelation because before then, it was thought that the adult brain couldnât change, that you couldnât teach an old dog new tricks,â Rebecca says. âTurns out you can.â
One of the studies, by scientists at the University of Oxford, scanned the brains of 24 people before and after they learnt to juggle, practising for half an hour every day for six weeks. All the learner jugglers grew more white matter in their parietal lobe, no matter how well they mastered the art of juggling. It was the act of practising juggling that improved the area of the brain that is responsible for connecting how we see with how we move.
Exercise Is Just As Good For Your Brain As It Is For Your Body
Aerobic exercise raises your heart rate and increases blood flow to your brain. As your increased breathing pumps more oxygen into your bloodstream, more oxygen is delivered to your brain. This leads to neurogenesisor the production of neuronsin certain parts of your brain that control memory and thinking. Neurogenesis increases brain volume, and this cognitive reserve is believed to help buffer against the effects of dementia.
It has been noted that exercise promotes the production of neurotrophins, leading to greater brain plasticity, and therefore, better memory and learning. In addition to neurotrophins, exercise also results in an increase in neurotransmitters in the brain, specifically serotonin and norepinephrine, which boost information processing and mood.
Activity In The Brain
This may come as a surprise — accustomed as you probably are to the idea that nine-tenths of your brain’s 100 billion or so neurons are wasting away in Margaritaville. But today’s brain researchers, who have much more sophisticated tools than the old electrode-zappers, have discovered that the human brain doesn’t seem to have any dormant regions. “It turns out, though, that we use virtually every part of the brain, and that the brain is active almost all the time,” Johns Hopkins University neurologist Barry Gordon explained to Scientific American in 2008 .
It is true that different parts of the brain do different things, and not all at the same time. But while not every single ounce of that three-pound hunk of goo inside your skull is necessarily working at any given moment, brain scans show that over a 24-hour period, pretty much the whole brain gets a workout, and most of the parts are continually active. Even when you’re sleeping, regions such as the frontal cortex, which controls higher-level thinking and self-awareness, and the somatosensory areas, which help you to sense your surroundings, remain active .
Is It Possible To Increase The Capacity Of Human Brain Like Lucy
I saw the film “Lucy” in 2015. The film says that humans can use 100% percent of the capacity of their brains.
According to my personal ideas, the capacity of the brain will changed based on the basic knowledge of a person. We all know Albert Einstein was a great knowledgeable human in the world. This level of knowledge can change by the time, for example he was arguably the best scientist or philosopher of his time he used his brain as much as possible for innovation.
At the present, there are many more scientists in the world, but the world is filled with knowledge, new technology etc. Man’s basic knowledge could be higher than a scientist in the past, because this knowledge is openly available everywhere. But the problem is that they don’t use their brain to the same level as Einstein or any other scientist that has lived in the past. That means that they don’t use the highest capacity of the brain.
So according to my idea, the capacity of the brain will vary depending on external environmental factors.
According to comments and suggestions in this article I read, I was unable to identify the truth: whether people can enhance their brain capacity like “Lucy”. And I need to know whether humans have a fixed brain capacity or not.
Most religions say that their saints had used 100% of their brain capacity. So what about other humans?

What Can We Do To Improve Our Brains Function
It isnât just older people encountering cognitive decline who should be working to improve their brains, Rebecca says.
âOlder people get the most focus, but thinking skills are important for everyone,â she says. âThe opportunity to improve the health of our brain is there for all of us at any stage of our life, and the earlier in life you start, the better the effects.â
Hereâs what we can all do to optimise the health and function of our brain.
Debunking The 10 Percent Myth
Neuroscientists point out a number of reasons why the 10% myth is false:
- Brain imaging scans clearly show that almost all regions of the brain are active during even fairly routine tasks such as talking, walking, and listening to music.
- If the 10% myth were true, people who suffer brain damage as the result of an accident or stroke would probably not notice any real effect. In reality, there isn’t a single area of the brain that can be damaged without resulting in some sort of consequence.
- We would not have evolved such large brains if we were only using a tiny portion of them.
- The brain uses approximately 20% of the body’s energy. It would make little evolutionary sense to have such a large portion of our energy resources utilized by such a tiny amount of the brain.
- Brain mapping research has yet to find any region of the brain that does not serve a function. “Numerous types of brain imaging studies show that no area of the brain is completely silent or inactive,” wrote Dr. Rachel C. Vreeman and Dr. Aaron E. Carroll in a study of medical myths. “Detailed probing of the brain has failed to identify the ‘non-functioning’ 90 percent.”
Unfortunately, the 10% myth remains both popular and persistent. It has been repeated in popular culture in everything from advertisements to television programs to Hollywood blockbusters such as the 2014 film Lucy starring Scarlett Johansson and Morgan Freeman.

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.

How Much Of Our Brain Capacity Do We Use
The human brain consists of about one billion neurons. Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brains memory storage capacity to something closer to around 2.5 petabytes .
Lets not get too technical about it and boredom strike you!
There are few myths about how much of capacity we use, one among those being that an average human being uses 10 percent of it and even in the movie Lucy Scarlett Johansson was portrayed to be having to use 10 percent of her brain at first.
Recent studies and 65 percent of the Americans let us know that the highly successful people tend to use their brains at 6 percent and Albert Einstein used 11 percent of his brain capacity and became the greatest scientist mankind had ever witnessed.
Here are some of the ways about how you can improve brain functions:
Eat a Balanced Diet
Eating a regular balanced diet reduced the risk of developing health issues that may lead to cardiovascular disease.
- Fruits and vegetables with dark skin
- Oily fish
Your Brain Is Mostly Fat
Consisting of minimum 60% fat, your brain is the fattiest organ in your body. This is why healthy fats, such as omega-3s and omega-6s, are vital for brain and overall body health. Healthy fat helps stabilize the cell walls in the brain. It can also reduce inflammation and helps the immune system function properly.

The Human Brain Gets Smaller As We Get Older
Human brain keeps developing until you are in your late 40s. It is the only organ in the human body to undergo development for such a long time. It also sees more changes than any other organ. Around mid-life, the brain will begin to shrink. However, size doesnt matter in the brain. There is no evidence that a larger brain is smarter than a smaller one.
The Myth Pervades Is Often Repeated By Self
From the outside, the brain is rather unremarkable: a lump of jelly-like fat weighing in at just under 1.4 kg.
Yet, it is basis for all our thoughts, feelings and actions and it has been called the most complex object in the known universe due to its network of 86 billion interconnected brain cells.
Because of that the brain fascinates us. We often look to neuroscience for explanations that help us figure out why we are the way we are.
Today arguments about how the brain works are drawn into discussions on education, personality, consumer behavior, and more.
But how much of that pop-culture knowledge is actually supported by science?
Unfortunately, some of the most wide-held beliefs are closer to fiction than to fact and in the following article and two more to come, I will debunk three myths about the brain.

Th Century Brain Researchers
How do you cook up an idea that’s so plausible and appealing, yet completely mistaken? You start by misinterpreting the incomplete scientific knowledge of the time. Then, take a couple of esteemed men of science and misquote them.
In the 19th and early 20th centuries, medical researchers who studied the brains of animals and stroke victims discovered that different brain areas controlled different activities. In the 1870s, for example, German physiologists Gustav Fritsch and Eduard Hitzig electrically stimulated a spot in a dog’s brain and noticed that the dog moved its right front paw. When they surgically removed that tissue from two other dogs, they noticed that the dogs not only couldn’t use the paw, but seemed unaware of it . Over the next half-century, other researchers eagerly zapped various parts of animal and human brains in an attempt to map brain function. But they were only able to figure out what about 10 percent of the brain did, because when they stimulated the other 90 percent, no muscles twitched. Scientists labeled that area the silent cortex because its function was unknown. We now know that’s the area that, among other things, controls language and abstract thinking . Non-scientists, however, mistakenly took this to mean that most of the human brain was on permanent vacation.
Humans Already Use Way Way More Than 10% Of Their Brains
Its a complex, constantly multi-tasking network of tissuebut the myth persists.
By now, perhaps youve seen the trailer for the new sci-fi thriller Lucy. It starts with a flurry of stylized special effects and Scarlett Johansson serving up a barrage of bad-guy beatings. Then comes Morgan Freeman, playing a professorial neuroscientist with the obligatory brown blazer, to deliver the films familiar premise to a full lecture hall: It is estimated most human beings only use 10 percent of the brains capacity. Imagine if we could access 100 percent. Interesting things begin to happen.
Johansson as Lucy, who has been kidnapped and implanted with mysterious drugs, becomes a test case for those interesting things, which seem to include even more impressive beatings and apparently some kind of Matrix-esque time-warping skills.
Of course, the idea that you only use 10 percent of your brain is, indeed, 100 hundred percent bogus. Why has this myth persisted for so long, and when is it finally going to die?
Unfortunately, not any time soon. A survey last year by The Michael J. Fox Foundation for Parkinson’s Research found that 65 percent of Americans believe the myth is true, 5 percent more than those who believe in evolution. Even Mythbusters, which declared the statistic a myth a few years ago, further muddied the waters: The show merely increased the erroneous 10 percent figure and implied, incorrectly, that people use 35 percent of their brains.

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.
Watch: How Much Of Our Brains Do We Really Use
Its commonly said that we humans use only about 10 percent of our brains, with some people attributing Einsteins 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, theyre 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, youll be able to set them 100-percent straight.
