Why We Use More Than 10 Percent Of Our Brain Power
A large body of research has shown humans tend to be cognitive misers . We cant afford to engage in hard thinking all the time because it isnt efficient. In our daily lives, we need to think at different levels in different situations. Too much thinking when engaging in trivial situations may drain cognitive resources needed for more complex decision making efforts. From an evolutionary perspective, cognitive shortcuts help us satisfy needs without over extending our brain resources.
A primary characteristic of well-learned information is the ease at which it is retrieved. As an example, when first learning statistics it is tiring and often a huge headache. As learning progresses, it becomes easier to perform statistical procedures; the brain areas involvedand their patterns of communicationhave changed. Producing the right outcome becomes more efficient. These changes lead to the use of less brain resources being dedicated to the task. A consequence of strong learning occurs across learning situations and is represented by strong learning/memory connections . However, being a cognitive miser under some circumstances may lead to poor decision making . Research involving rational thinking/critical thinking provides evidence that it is often this lack of thinkingor cognitive miserlinessthat leads to irrationality. In the cognitive science literature, this is referred to as a processing problem.;;
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.

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.

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.
An Unlikely Mismanagement Of The Bodys Resources
Today, clinical experience clearly contradicts the 10 percent myth: damage to small areas of the brain, for example caused by a stroke, can have devastating effects on the patients abilities.
Modern brain imaging methods also disprove the idea by showing that much of the brain is active during most tasks.
Also from an evolutionary perspective the 10 percent-myth is unlikely: Brains are expensive, they consume roughly 20-25 percent of the bodys entire energy budget.
If the majority of the brain was left to lie fallow this would be such an outrageous mismanagement of the bodys resources that an organism with this strategy is unlikely to have survived evolutionary pressure.

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.
Cholesterol Is Key To Learning And Memory
The brain has a higher cholesterol content than any other organ.; In fact, about 25% of the bodys cholesterol resides within the brain. The brain is highly dependent on cholesterol, but its cholesterol metabolism is unique. Because the blood-brain barrier prevents brain cells from taking up cholesterol from the blood, the brain must produce its own cholesterol. The brains cholesterol is much more stable than the cholesterol in other organs, but when it breaks down, it is recycled into new cholesterol right in the brain.
Where Did The Myth About Our Brain Come From
Like other widely held but false ideas, the myth that we only use 10% of our brains has evolved from a series of sources and taken on a life of its own.
Everyone from Albert Einstein and psychologist William James, to neurosurgeon Karl Lashley has contributed to the myth, and its origins date back as far as the early 1900s.
Hollywood has even weighed in on the subject with Scarlett Johanssonâs 2014 movie Lucy, based on the premise that humans only use a 10th of their craniumâs capacity. Morgan Freeman, who plays a neurologist in the film says, âIt is estimated most human beings only use 10% of their brainâs capacity. Just imagine if we could access 100%.â
When Lucy taps into her brainâs full potential with the help of a cognitive-boosting drug, she can absorb information instantly, travel through time in her mind, and become the spoon-bending, ninja-skilled warrior weâd all quite like to be.
âThis myth has perpetuated because itâs a really inspirational concept,â says clinical neuropsychologist Dr Rebecca Segrave. âSadly, itâs entirely inaccurate.â
Rebecca is Deputy Director of Monash Universityâs BrainPark, a world-first clinical neuroscience research facility supported by nib foundation and dedicated to creating better outcomes for people living with addictions.

Technology has been a boon for our generation however in todays world, technology affects our;brain negatively. In many cases, it has been observed that internet/gaming addiction leads to;shrinkage of tissue;volume in the brain. Apart from this, it leads to;anxiety,;depression;and sometimes to even suicidal thoughts thus disturbing our;mental equilibrium. It is even recommended that we should stop relying on machines for basic functions such as calculators or GPS navigators. This way we do not allow our brains to exercise which in turn inhibits in expanding our brains beyond its limits.

The Origins Of The Myth
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.
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.

Do You Only Use 10 Percent Of Your Brain
Humans are sentient beings, and of course, our brains are the cause. Do we only use 10 percent of our brain though? Lets carry on.
In the 1900s, a psychologist named William James stated, The average person rarely achieves but a small portion of his or her potential. Over the years, this quote has been turned into only using 10% of your brain. Even Albert Einstein has exclaimed something that could support this myth.
Some people believe that if we used the other 90 percent of our brain, we would have the power to move objects, just with our mind. Maybe you could even read other minds, maybe we could speak telepathically.;Interesting;enough,;47 percent of teachers actually;believe;in;the myth.
Scientists say that this myth is false. We have to perform many acts in our life such as, reading, communication, breathing, locomotion, problem solving, creation, thinking, etc.;Could you propose all that with only 10 percent of your brain? You wouldnt be able to hold much memory either.
This myth is false. We all use 100 percent of our brain. If;we only used 10 percent of;our brain, it would be 90 percent smaller.;Your whole brain is always active. Each part of the brain has a purpose. There is no actual evidence that you use 10 percent of your brain. If the 10 percent brain myth was real, then people with brain damage would have no;consequence. ;Also, why would we have such large brains if you only use a small fraction of it?
Thanks for reading my post. See you next time.
What Does It Mean To Use Only 10% Of Your 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.

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.
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.

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.

Reading Out Loud Uses Different Brain Circuits Than Reading Silently
Reading aloud promotes brain development. Children first learn to read by speaking words out loud. Once that knowledge is established, then they learn to read to themselves.;Its indeed one of the strange facts about the brain because we usually teach our children to read and talk politely. But to promote brain development in your child, you should read and talk aloud in front of them.
Thoughts On Do We Only Use 10 Percent Of Our Brains: A Misconception Or An Extraordinary Belief
I think this belief is notable because it evolved out of scientific research. Most of these beliefs seem to sprout from attempts to rationalize seemingly extraordinary phenomenon, but this one comes out of the scientific attempt at an explanation. It feels like that is a relatively uncommon origin can you think of any other extraordinary beliefs that stem from scientific research? The closest ones that come to mind for me are those about pharmaceuticals and HIV/AIDS and cancer being manufactured by the U.S. government.
This belief is SO popular! As soon as I saw that this had been posted, I was so frustrated with myself because of the immense popularity associated with it ! There have been a handful of movies that centers on this premise of only using 10% of our brains. One movie that comes to mind is Lucy, which came out in 2014 with Scarlett Johansson and Morgan Freeman. Your point that you cited from that stated, we wouldnt have such a large brain if we were only allowed to use a small portion of it is so crucial! It guides one to really think about our brains and our capacity for learning skills, and performing every day tasks. Im also very fascinated with Neuroscience so this was a very easy read for me. Thank you for your post!!
Thanks a lot, I know right the way movies and documentaries use this myth has kind of blown it way out of proportion. Especially when this kind of visual media portrays is, it influences people largely.
