[The Harnett lab](https://www.markharnett.org/) studies the computational power of neurons, that is, how neural networks rapidly process massive amounts of information.\\n\\n“All of our brain is constantly in use and consumes a tremendous amount of energy,” Halgren says. “Despite making up only two percent of our body weight, it devours 20 percent of our calories.” This doesn’t appear to change significantly with different tasks, from typing on a computer to doing yoga. “Even while we sleep, our entire brain remains intensely active.”\\n\\n## **When did this myth take root?**\\n\\nMila Halgren is a PhD student in MIT’s Department of Brain and Cognitive Sciences. Photo: Mila Halgren\\n\\nThe myth is thought to have gained traction when scientists first began exploring the brain’s abilities but lacked the tools to capture its exact workings. In 1907, William James, a founder of American psychology, suggested in his book “The Energies of Men” that “we are making use of only a small part of our possible mental and physical resources.” This influential work likely sparked the idea that humans access a mere fraction of the brain—setting this common misconception ablaze.\\n\\nBrainpower lore even suggests that Albert Einstein credited his genius to being able to access more than 10 percent of his brain. However, no such quote has been documented and this too is perhaps a myth of cosmic proportion.\\n\\nHalgren believes that there may be some fact backing this fiction. “People may think our brain is underutilized in the sense that some neurons fire very infrequently—once every few minutes or less. But this isn’t true of most neurons, some of which fire hundreds of times per second,” she says.\\n\\nIn the nascent years of neuroscience, scientists also argued that a large portion of the brain must be inactive because some people experience brain injuries and can still function at a high level, like the famous case of Phineas Gage. Halgren points to the brain’s remarkable plasticity—the reshaping of neural connections. “Entire brain hemispheres can be removed during early childhood and the rest of the brain will rewire and compensate for the loss. In other words, the brain will use 100 percent of what it has, but can make do with less depending on which structures are damaged.”\\n\\n## **Is there a limit to the brain?**\\n\\nIf we indeed use our entire brain, can humans tease out any problem? Or, are there enigmas in the world that we will never unravel?\\n\\n“This is still in contention,” Halgren says. “There may be certain problems that the human brain is fundam\",\"totalChars\":6575,\"truncated\":false,\"url\":\"https://mcgovern.mit.edu/2024/01/26/do-we-use-only-10-percent-of-our-brain\"},{\"chars\":4000,\"evidenceId\":\"0x09a05d869da0d0b0e9961b7a7e0e52fcaf8255cdfe007daae094bff5911318fa\",\"from\":0,\"ref\":\"p2\",\"text\":\"[New Issue: Orbital Catastrophe Ahead?

Along with performing millions of mundane acts, it composes concertos, issues manifestos and comes up with elegant solutions to equations. It's the wellspring of all human feelings, behaviors, experiences as well as the repository of memory and self-awareness. So it's no surprise that the brain remains a mystery unto itself.\\n\\nAdding to that mystery is the contention that humans \\\"only\\\" employ 10 percent of their brain. If only regular folk could tap that other 90 percent, they too could become savants who remember to the twenty-thousandth decimal place or perhaps even have telekinetic powers.\\n\\nThough an alluring idea, the \\\"10 percent myth\\\" is so wrong it is almost laughable, says neurologist Barry Gordon at Johns Hopkins School of Medicine in Baltimore. Although there's no definitive culprit to pin the blame on for starting this legend, the notion has been linked to the American psychologist and author William James, who argued in _The Energies of Men_ that \\\"We are making use of only a small part of our possible mental and physical resources.\\\" It's also been associated with Albert Einstein, who supposedly used it to explain his cosmic towering intellect.\\n\\nThe myth's durability, Gordon says, stems from people's conceptions about their own brains: they see their own shortcomings as evidence of the existence of untapped gray matter. This is a false assumption. What is correct, however, is that at certain moments in anyone's life, such as when we are simply at rest and thinking, we may be using only 10 percent of our brains.\\n\\n\\\"It turns out though, that we use virtually every part of the brain, and that \\\\[most of\\\\] the brain is active almost all the time,\\\" Gordon adds. \\\"Let's put it this way: the brain represents three percent of the body's weight and uses 20 percent of the body's energy.\\\"\\n\\nThe average human brain weighs about three pounds and comprises the hefty cerebrum, which is the largest portion and performs all higher cognitive functions; the cerebellum, responsible for motor functions, such as the coordination of movement and balance; and the brain stem, dedicated to involuntary functions like breathing. The majority of the energy consumed by the brain powers the rapid firing of millions of neurons communicating with each other. Scientists think it is such neuronal firing and connecting that gives rise to all of the brain's higher functions. The rest of its energy is used for controlling other activities—both unconscious activities, such as heart rate, and conscious ones, such as driving a car.\\n\\nAlthough it's true that at any given moment all of the brain's regions are not concurrently firing, brain researchers using imaging technology have shown that, like the body's muscles, most are continually active over a 24-hour period. \\\"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.\\n\\nTake the simple act\",\"totalChars\":11137,\"truncated\":false,\"url\":\"https://www.scientificamerican.com/article/do-people-only-use-10-percent-of-their-brains\"}],\"tool\":\"open_many\"}","role":"user"},{"content":"I now have strong evidence from two credible sources (MIT McGovern Institute and Scientific American) that debunk the \"10% of the brain\" myth.

In _Phenomenon_ (1996), John Travolta gains the ability to predict earthquakes and instantly learns foreign languages. Scarlett Johansson becomes a superpowered martial-arts master in _Lucy_ (2014). And in _Limitless_ (2011) Bradley Cooper writes a novel overnight.\\n\\nThis ready-made blueprint for fantasy films is also a favorite among the general public. In a [survey](https://www.michaeljfox.org/foundation/publication-detail.html?id=484), 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.\\n\\nHow do we know? For one thing, if we needed only 10 percent of our brain, the majority of brain injuries would have no discernible consequences, since the damage would affect parts of the brain that weren’t doing anything to begin with.
