Answer to Question #62862 in Other Biology for Ali
percentage of brain working
Human beings use virtually every part of their brains. Moreover, over the course of an average day, humans use nearly 100% of their brains. The idea that "most people" only use "10% of their brain" is a myth. Despite brain only makes up 3-5% of the body's weight, it uses up an incredible 20% of the body's resources in terms of oxygen and glucose.
