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.
Your Brain Does Creative Work Better When Youre Tired
When I explored the science of our body clocks and how they affect our daily routines, I was interested to find that a lot of the way Id planned my days wasnt really the best way to go about it. The way we work, in particular, actually has a lot to do with the cycles of our body clocks.
Heres how it breaks down:
If youre a morning lark, say, youll want to favor those morning hours when youre feeling more fresh to get your most demanding, analytic work done. Using your brain to solve problems, answer questions and make decisions is best done when youre at your peak
For night owls, this is obviously a much later period in the day.
On the other hand, if youre trying to do creative work, youll actually have more luck when youre more tired and your brain isnt functioning as efficiently. This sounds crazy, but it actually makes sense when you look at the reasoning behind it. Its one of the reasons why great ideas often happen in the shower after a long day of work.
If youre tired, your brain is not as good at filtering out distractions and focusing on a particular task. Its also a lot less efficient at remembering connections between ideas or concepts. These are both good things when it comes to creative work, since this kind of work requires us to make new connections, be open to new ideas and think in new ways. So a tired, fuzzy brain is much more use to us when working on creative projects.
Ten Percent Of The Brain Myth
The 10 percent of the brain myth asserts that humans generally use only 10 percent of their brains. It has been misattributed to many celebrated people, notably Albert Einstein. By extrapolation, it is suggested that a person may harness this unused potential and increase intelligence.
Changes in grey and white matter following new experiences and learning have been shown, but it has not yet been proven what the changes are. The popular notion that large parts of the brain remain unused, and could subsequently be “activated”, rests in folklore and not science. Though specific mechanisms regarding brain function remain to be fully describede.g. memory, consciousnessthe physiology of brain mapping suggests that all areas of the brain have a function and that they are used nearly all the time.

It Is A Myth That Humans Only Use 10% Of Our Brain
We actually use all of it. Were even using more than 10 percent when we sleep. Although its true that at any given moment all of the brains regions are not concurrently firing, brain researchers using imaging technology have shown that, like the bodys muscles, most are continually active over a 24-hour period.
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.

Introversion And Extroversion Come From Different Wiring In The Brain
I just recently realized that introversion and extroversion are not actually related to how outgoing or shy we are, but rather how our brains recharge.
Research has actually found that there is a difference in the brains of extroverted and introverted people in terms of how we process rewards and how our genetic makeup differs. For extroverts, their brains respond more strongly when a gamble pays off. Part of this is simply genetic, but its partly the difference of their dopamine systems as well.
An experiment that had people take gambles while in a brain scanner found the following:
When the gambles they took paid off, the more extroverted group showed a stronger response in two crucial brain regions: the amygdala and the nucleus accumbens.
The nucleus accumbens is part of the dopamine system, which affects how we learn, and is generally known for motivating us to search for rewards. The difference in the dopamine system in the extroverts brain tends to push them towards seeking out novelty, taking risks and enjoying unfamiliar or surprising situations more than others. The amygdala is responsible for processing emotional stimuli, which gives extroverts that rush of excitement when they try something highly stimulating which might overwhelm an introvert.
Drugs Create Holes In Our Brains
Physical trauma is the only way we can actually put a hole in our brain. While drugs also affect the function of the brains neurotransmitters, the effect can be reversed. In the event of chronic drug use, however, the overstimulation and replacement of neurotransmitters like dopamine can result in deterioration of mental functioning over time.

Effects Of Technology Advancement On The Brain
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.
Do We Really Use Only 10 Percent Of Our Brain
Its one of Hollywoods favorite bits of pseudoscience: human beings use only 10 percent of their brain, and awakening the remaining 90 percentsupposedly dormantallows otherwise ordinary human beings to display extraordinary mental abilities. In Phenomenon , John Travolta gains the ability to predict earthquakes and instantly learns foreign languages. Scarlett Johansson becomes a superpowered martial-arts master in Lucy . And in Limitless Bradley Cooper writes a novel overnight.
This ready-made blueprint for fantasy films is also a favorite among the general public. In a survey, 65 percent of respondents agreed with the statement, People only use 10 percent of their brain on a daily basis. But the truth is that we use all of our brain all of the time.
Weve been able to back up these logical conclusions with hard evidence. Imaging techniques, such as positron emission tomography and functional magnetic resonance imaging , allow doctors and scientists to map brain activity in real time. The data clearly shows that large areas of the brainfar more than 10 percentare used for all sorts of activity, from seemingly simple tasks like resting or looking at pictures to more complex ones like reading or doing math. Scientists have yet to find an area of the brain that doesnt do anything.

Anatomy Of The Human Brain
The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Each hemisphere consists of four lobes: the frontal, parietal, temporal and occipital. The rippled surface of the cerebrum is called the cortex. Underneath the cerebrum lies the brainstem, and behind that sits the cerebellum.
The frontal lobe is important for cognitive functions, such as thought and planning ahead, and for the control of voluntary movement. The temporal lobe generates memories and emotions. The parietal lobe integrates input from different senses and is important for spatial orientation and navigation. Visual processing takes place in the occipital lobe, near the back of the skull.
The brainstem connects to the spinal cord and consists of the medulla oblongata, pons and midbrain. The primary functions of the brainstem include relaying information between the brain and the body supplying most of the cranial nerves to the face and head and performing critical functions in controlling the heart, breathing and levels of consciousness .
The cerebellum lies beneath the cerebrum and has important functions in motor control. It plays a role in coordination and balance and may also have some cognitive functions.
What’s The Difference Between The Left Brain And Right Brain
The human brain is divided into two hemispheres, the left and right, connected by a bundle of nerve fibers called the corpus callosum. The hemispheres are strongly, though not entirely, symmetrical. Generally, the left brain controls the muscles on the right side of the body, and the right brain controls the left side. One hemisphere may be slightly dominant, as with left- or right-handedness.
The popular notions about “left brain” and “right brain” qualities are generalizations that are not well supported by evidence. However, there are some important differences between these areas. The left brain contains regions that are involved in language production and comprehension and is also associated with mathematical calculation and fact retrieval, Holland said. The right brain plays a role in visual and auditory processing, spatial skills and artistic ability more instinctive or creative things, Holland said though these functions involve both hemispheres. “Everyone uses both halves all the time,” he said.

Does The Brain Stay Alive After A Person Dies
April 2019 marked a milestone for both the initiative and neuroscience research at large: BRAIN Initiative researcher Nenad Sestan, of the Yale School of Medicine, published a report in the journal Nature, revealing that his research team had restored circulation and some cellular functions to pig brains four hours after the animals’ deaths, Live Science previously reported. The results challenged the prevailing view that brain cells are suddenly and irreversibly damaged shortly after the heart stops beating. The researchers did not observe any signs of consciousness in the brains, nor were they trying to on the contrary, the researchers injected pig brains with chemicals that mimicked blood flow and also blocked neurons from firing. The researchers emphasized that they did not bring the pig brains back to life. They did, however, restore some of their cellular activity.
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.

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.

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.

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.
