What Percentage Do We Use Of Our Brain – The brain is a very complex organ that plays a fundamental role not only in thinking, but in all bodily functions. It is divided into two halves, the right and left halves of the brain. Certain areas are responsible for different functions, but the brain functions as a whole.
The human brain is a complex organ. It weighs about 3 pounds, contains about 100 billion neurons and 100 trillion connections. Your brain is the control center for everything you think, feel and do.
What Percentage Do We Use Of Our Brain
The two sides of your brain look very similar, but there are big differences in how they process information. Despite their contrasting styles, your two hemispheres don’t operate independently of one another.
Steps To Protect Your Brain
Nerve fibers connect different parts of your brain. If a brain injury severs the connection between the two sides, you can still function normally. However, the lack of integration will cause some damage.
The human brain is constantly rearranging itself. It can be adapted to changes, both physical and life experiences. It is specially made for learning.
As scientists continue to map the brain, we are gaining better insight into which parts control the necessary functions. This information is critical to advancing research into brain disease and injury and how to recover from it.
The theory is that people are left-brained or right-brained, meaning one side of their brain is dominant. If you are mostly analytical and methodical in your thinking, then in theory you are left-brained. If you tend to be more creative or artistic, you’re right.
Left Brain Vs. Right Brain: What’s The Difference?
This theory is based on the fact that the two hemispheres of the brain work differently. It was first uncovered in the 1960s thanks to the research of psychobiologist and Nobel Prize winner Roger W. Sperry.
The left brain is more verbal, analytical and organized than the right brain. This is sometimes called a digital brain. He is better at things like reading, writing, and arithmetic.
The right brain is more visual and intuitive. People sometimes refer to it as an analog brain. He has a more creative and less organized way of thinking.
We know that the two sides of our brain are different, but does that mean we have the same dominant brain as we have a dominant hand?
Ways To Improve Your Hippocampus Function
They found no evidence that this theory was correct. An MRI of 1,000 people revealed that the human brain doesn’t actually favor one side over the other. The network on one side is generally not stronger than the network on the other.
Collections of nerve fibers connect the two hemispheres and create information highways. Although the two sides operate differently, they work together and complement each other. You don’t only use one side of your brain at a time.
Whether you are performing logical or creative functions, you receive information from both sides of your brain. For example, people associate language with the left brain, but the right brain helps you understand context and tone. The left brain handles math equations, but the right brain helps with comparisons and rough approximations.
General personality traits, individual preferences, or learning styles don’t translate into left- or right-brained ideas.
You’ve Likely Heard Of The Brain’s Gray Matter
However, the fact is that the two sides of your brain are different, and certain areas of your brain have specializations. The exact areas of some functions may vary slightly from person to person.
According to the Alzheimer’s Association, keeping the brain active through mentally demanding activities, such as learning a new skill, can have short-term and long-term benefits for brain health. They also suggest that a lack of mental stimulation may increase the likelihood of developing Alzheimer’s disease.
Aerobic exercise “positively affects” episodic memory in adults aged 55 years and older with a diagnosis of dementia.
Nutrition is also very important to help keep both sides of the brain in top condition. Try eating a nutrient-dense diet that includes:
Grey Matter Vs White Matter In The Brain
For your brain to help neurons communicate with each other, get rid of toxins that can build up when you’re awake, and keep your memory sharp.
Read about and hear other people’s creative ideas. You may find a seed of an idea that you can nurture or let your imagination run wild.
Trying something new. Take up a creative hobby like playing an instrument, drawing, or telling a story. Relaxing hobbies can help your mind wander to new places.
Look inside. This can help you gain a deeper understanding of yourself and what makes you tick. Why are you drawn to certain activities and not others?
Do We Really Only Use 10% Of Our Brain?
Stay fresh. Break your usual patterns and get out of your comfort zone. Take a trip to a new place. Immerse yourself in another culture. Take courses in unknown subjects.
Even something as creative as music takes time, patience, and practice. The more you practice new activities, the more your brain adapts to new information.
Whether you are constructing a complex algebraic equation or painting an abstract work of art, both sides of your brain are actively participating and providing input.
Neither one is strictly left- or right-brained, but you can use your strengths and continue to broaden your mental horizons. A healthy, typical brain is capable of lifelong learning and boundless creativity, especially when fueled by proper nutrition, a dose of physical exercise, and mental stimulation.

Although many people still believe the myth that we only use 10% of our brain, the truth is we use it all (not all at once).
According to a 2013 study by the Michael J. Fox Foundation, nearly two-thirds (65%) of Americans believe that people only use 10 percent of their brain. So this is a common misconception. If you’ve ever wondered what percentage of our brains we actually use, here’s a science-based answer. Also, explore how the “10% Myth” came to be and how it actually contains a seed of truth.
Humans Already Use Way, Way More Than 10% Of Their Brains
People use their whole brain or 100 percent. We know this from magnetic resonance imaging (MRI) and positron emission tomography (PET) scans, which show which parts of the brain are active. Even so, we don’t use our whole brain all the time. Only 10 to 35 percent of your brain is active while performing any task. But throughout the day, all of this will come in handy. Your brain is active even when you sleep. The only time that part of the brain “goes dark” is when the tissue is severely damaged.
No one is sure how the “10 percent myth” came about. This idea has its roots at least to the end of the 19th century. In the 1890s, Harvard psychologist William James stated in a lecture that people fulfill only a fraction of their mental potential. James did not give a specific fraction, but a 1929 advertisement for the World Almanac included the statement: “There is no limit to what the human brain can achieve. Scientists and psychologists tell us that we only use about ten percent of our brain power.” Writers John W. Campbell and Lowell Thomas popularized the idea of the “10 percent,” and the idea took off immediately. In the early 20th century, this was not dismissed as scientists discovered that most of the brain is made up of glial cells, which do not perform the same function as neurons.
However, at the beginning of the 20th century, scientists understood that humans use more than 10 percent of their brain. Today there is mounting evidence that the whole brain is used, and reasons why this is true:
As it turns out, in the 21st century, microstructural analysis lends credence to the argument that you’re not using 100 percent of your brain. Whether this smaller percentage is 10 percent or a higher number is unknown.
Reasons Why Your Brain Needs Water
A 2020 rat brain study by Saski et al. demonstrated that not all neurons in an area fire in response to a stimulus. This study uses electrodes to monitor individual neurons, providing a much more detailed picture of brain response compared to an MRI or PET. Think of an MRI or PET scan like seeing the entire monitor light up, while electrodes pinpoint which pixels on your monitor are lighted or dark. An MRI scan can show activity across areas, but an analysis of the electrodes shows exactly which neurons are active. In Saskia’s study, only 23 percent of the neurons in the rat visual cortex responded to visual stimuli. Another study by Hromádek et al. using mice, similar results were obtained in the auditory cortex in response to sound.
While this study involved rodents, the idea that the human brain uses the behavior of firing “rarely” makes perfect sense. Over time, all neurons fire, but only a few are active
