Answer :
The idea that humans only use 10% of their brains is a popular myth, likely stemming from misunderstandings or misinterpretations of neurological research. In reality, neuroscience research shows that we use all parts of our brain, and much of the brain is active most of the time.
Here’s a step-by-step explanation:
Origins of the Myth: The 10% myth may have originated in the early 20th century, possibly from statements by psychologists like William James or, inaccurately, from misquoted or misunderstood neurological studies from that era.
What Modern Neuroscience Says: Advanced imaging techniques, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), have allowed scientists to map brain activity quite thoroughly. These studies show that many areas of the brain are active even when a person is at rest, and virtually all parts of the brain have a known function.
Brain Cells and Function: The brain consists of both gray matter (neurons) and white matter (supporting glial cells). Both types of cells have complex roles in cognitive and physiological processes. The interconnectedness and activity of these cells contribute to cognitive functions.
Energy Consumption: The brain consumes about 20% of the body’s energy, even though it only makes up about 2% of body weight. This high energy consumption supports the brain's extensive functionality and constant activity.
Importance of All Parts: Each brain region informs different functions, like motor skills, sensory processing, language, and decision-making. Damage to even small areas of the brain can have significant impacts on these abilities, indicating that we indeed need and use all parts of our brain.
In conclusion, the complete unlocking or utilization of the brain is a misnomer because scientific evidence supports that all parts of the brain have a purpose and are used consistently.
