Humans Use Only 10% of Their Brain

Log by: Shahid Khan

The claim that humans use only 10% of their brain is one of the most common myths in modern culture. It is frequently repeated in movies, motivational speeches, and self-help content, often implying that unlocking the remaining 90% would lead to extraordinary abilities. Modern neuroscience, however, has completely disproved this idea. Brain imaging technologies such as MRI, PET, and fMRI show that humans use most regions of the brain every day, even during simple activities like talking, walking, thinking, or resting. Different areas control specific functions including movement, memory, emotions, senses, and decision-making. Damage to even small brain regions can cause serious impairments, which would not happen if large portions were unused. The myth likely emerged in the early 20th century from misunderstood scientific research and was later amplified by popular media. Scientific consensus today confirms that nearly the entire brain is active and essential for normal human functioning.
