As a cognitive neuroscientist with a focus on the study of the brain's cognitive functions and its capacity, I can tell you that the idea that humans only use a small fraction of their brain's capacity is a myth. This misconception has been perpetuated in popular culture and has been attributed to many influential figures, including Albert Einstein. However, it's important to clarify that this is not based on scientific evidence.
The brain is an organ of remarkable complexity and efficiency. It is composed of billions of neurons, each capable of forming thousands of synaptic connections with other neurons. The brain is not a static organ; it is highly dynamic, with different regions being active and engaged depending on the task at hand. Here's a breakdown of why the "10 percent" myth is scientifically unfounded:
1. Neural Imaging Studies: Modern neuroscience utilizes advanced imaging techniques such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) scans. These tools allow us to see which parts of the brain are active during various cognitive tasks. Studies have shown that even during simple tasks, multiple areas of the brain are engaged, contradicting the idea that only a small part of the brain is used.
2. Brain Damage and Recovery: Clinical observations of patients with localized brain damage demonstrate that different brain regions serve specific functions. If the brain were only using 10 percent of its capacity, damage to a particular area would not result in the loss of specific functions, as the "unused" 90 percent could compensate. However, this is not the case; damage to certain areas can lead to significant impairments.
3. Energy Consumption: The brain is a high-energy-demanding organ, consuming about 20 percent of the body's total energy despite representing only about 2 percent of body weight. If 90 percent of the brain were truly unused, it would not make evolutionary sense for such a significant portion of the body's resources to be allocated to an underutilized organ.
4. Evolutionary Perspective: From an evolutionary standpoint, it is unlikely that humans would develop such a large and metabolically expensive organ only to use a fraction of it. Evolution favors efficiency and function, so the idea that a significant portion of the brain would be left dormant is not supported by evolutionary theory.
5. Brain Plasticity: The brain is highly adaptable and can reorganize its functions to some extent. This plasticity allows for recovery from injury and learning new skills. If the brain were only using a small portion of its capacity, there would be less need for such adaptability.
6. Cognitive Tasks and Brain Engagement: Different cognitive tasks engage different parts of the brain. For example, language processing primarily involves the Broca's and Wernicke's areas, while visual tasks engage the occipital lobe. The fact that specific tasks engage specific brain regions indicates that the brain is using more than just a small percentage of its capacity.
7.
Misconceptions and Media Influence: The myth may have originated from a misunderstanding or oversimplification of scientific concepts. It has been perpetuated by media and self-help literature, which often emphasize the idea of "untapped potential" for motivation or marketing purposes.
Regarding Albert Einstein, there is no evidence to suggest that he used a different percentage of his brain than the average person. In fact, Einstein's own intellectual achievements were the result of his exceptional ability to conceptualize and visualize complex ideas, not because he used a greater percentage of his brain's capacity.
In conclusion, the notion that humans only use 10 percent of their brain is a myth that has been debunked by scientific research and understanding of the brain's functions. The brain is a highly active and fully utilized organ, with different regions serving specific and important roles in our cognitive and physiological processes.

The 10 percent of the brain myth is a widely perpetuated urban legend that most or all humans only use 10 percent (or some other small percentage) of their brains. It has been misattributed to many people, including Albert Einstein.
