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.
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.
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.

The cerebrum makes up 85% of the brains weight, and the brain makes up about 2% of a humans body weight. The texture of the brain is like a firm jelly. The heaviest normal human brain weighed 4.43 pounds. It belonged to the Russian Writer Ivan Turgenev. And the smallest brain, just 2.41 pounds, belonged to a woman.
The Using Only 10 Percent Of Your Brain Myth
The human brain is complex and still quite mysterious. It is perhaps for this reason why so many myths about how the brain works persist, despite plenty of evidence to the contrary. One of the most common of these myths is often referred to as the 10% of brain myth, or the idea that human beings really only fully utilize a tiny percentage of their brain’s power and potential.
The popular and widely-spread belief that we only use or have access to 10% of our brain’s power is often used to speculate about the extent of human abilities if only we could utilize our brain’s full capacity. People often experience the shortcomings of their own mental abilities, such as failing to understand a complex math problem or forgetting some vital piece of information. It is perhaps because of this that people frequently feel they possess some untapped potential, if only they could unlock that inaccessible portion of their mind.
In reality, the 10% claim is 100% myth. You use all of your brain. The only instances where there are unused regions of the brain are those in which brain damage or disease has destroyed certain regions.

Do We Really Use Only 10 Percent Of Our Brains
Barry L. Beyerstein of the Brain Behavior Laboratory at Simon Fraser University in Vancouver explains.
Whenever I venture out of the Ivory Tower to deliver public lectures about the brain, by far the most likely question I can expect as the talk winds up is, “Do we really only use 10 percent of our brains?” The look of disappointment that usually follows when I say it isn’t so strongly suggests that the 10-percent myth is one of those hopeful shibboleths that refuses to die simply because it would be so darn nice if it were true. I’m sure none of us would turn down a mighty hike in brainpower if it were attainable, and a seemingly never-ending stream of crackpot schemes and devices continues to be advanced by hucksters who trade on the myth. Always on the lookout for a “feel-good” story, the media have also played their part in keeping the myth alive. A study of self-improvement products by a panel of the prestigious National Research Council, Enhancing Human Performance, surveyed an assortment of the less far-fetched offerings of the “brain booster” genre and came to the conclusion that there is no reliable substitute for practice and hard work when it comes to getting ahead in life. This unwelcome news has done little, however, to dissuade millions who are comforted by the prospect that the shortcut to their unfulfilled dreams lies in the fact that they just haven’t quite found the secret to tap this vast, allegedly unused cerebral reservoir.
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.

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.

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.

Do We Really Only Use 10% Of Our Brain
There is a common misconception that humans only use 10% of their brain and that the other 90% contains untapped potential. This is a myth;and is off by about 90%.
The average human;uses 100% of the brain on a daily basis, and there is no silent areas of a normal healthy human brain.
Throughout an average day, evidence suggests humans use most of, if not all of their brains, just as they use most, if not all their muscles. At certain points in the day parts of the brain may be less active, and some tasks may only require some areas of the brain to perform them, but no part of the brain is unused.
It is likely that this myth is an extension of the idea that we used to think that parts of the prefrontal cortex were silent areas.
Today we can prove,;with the advent of the modern methodologies of molecular neuroscience and functional neuroimaging, that activity can be demonstrated in all brain areas, even in those areas which previously were believed to be inactive. Even the most passive areas arent inactive.
The brain, like all organisms, conserves power when it can. Thus, some parts of the more passive and less active parts of the brain were only detected with;recent technology.
TIP: Just because we dont have unused portions of our brains doesnt mean we dont have potential. Our neural;networks have near limitless untapped potential; it is a matter of neuroplasticity and not unused;space.
Do People Only Use 10 Percent Of Our Brains
Its appealing to think we could be smarter if only we applied more of our brain power. Unfortunately, the idea that people only use 10% of our brains and could use more is not true. This persistent myth may have originated as early as 1908 when William James wrote, We are making use of only a small part of our possible mental and physical resources. . The idea has been perpetuated by many individuals claiming extraordinary powers from tapping into the unused portions of their minds.
According to the Department of Neurology at UAMS, individuals without a neurological condition use almost all of their brain. Your brain is constantly active and involved in all of the conscious and unconscious activities of your body. In fact, the brain uses approximately 20 percent of the bodys energy. This is because many parts of the brain are active during different of activities, with neurons firing back and forth. So everything from reading a book to throwing a ball requires a significant portion of your 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.
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.

Brain Activity Can Power A Small Light Bulb
When you are awake, your brain generates about 12-25 watts of electricity which is enough to power a small light bulb. The brain also works fast. The information going from your arms/legs to your brain travels at a speed of 150-260 miles per hour. The brain consumes glucose from the body to produce this amount of the energy.
Where Does The 10 Percent Myth Come From
Its not clear how this myth began, but there are several possible sources.
In an article published in a 1907 edition of the journal Science, psychologist and author William James argued that humans only use part of their mental resources. However, he did not specify a percentage.
The figure was referenced in Dale Carnegies 1936 book How to Win Friends and Influence People. The myth was described as something the authors college professor used to say.
There is also a belief among scientists that neurons make up around 10 percent of the brains cells. This may have contributed to the 10 percent myth.
The myth has been repeated in articles, TV programs, and films, which helps to explain why it is so widely believed.
Like any other organ, the brain is affected by a persons lifestyle, diet, and the amount that they exercise.
To improve the health and function of the brain, a person can do the following things.

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.
