The idea that humans only use 10% of their brains is a myth. Brain imaging studies show that we use all parts of our brains for various functions, including thinking, movement, and processing sensory information. Different areas of the brain are activated depending on the task at hand, indicating that the entire brain is involved in our daily activities. This misconception may have originated from early neurological research or misinterpretations of brain function. In reality, even during sleep, many regions of the brain remain active, managing essential processes. Understanding how the brain works helps debunk myths and promotes a better appreciation of its complexity.
