Le cerveau humain n'est utilisé qu'à 10 % de son potentiel.

The claim that humans use only 10% of their brain is a widespread myth that has been repeatedly debunked by neuroscience research. Although popular culture and some outdated or non-scientific sources perpetuate this idea, modern brain imaging and neurological studies show that virtually all parts of the brain have identifiable functions and are active over the course of a day. The myth likely originated from misunderstandings or misrepresentations of early neurological research but lacks empirical support. None of the consulted sources, including those linked to reputable institutions, provide evidence supporting the claim; instead, they emphasize that the brain is used extensively, not just a small fraction. This consensus across diverse sources confirms that the 10% usage claim is false.
