Do Humans Really Only Use 10% Of Their Brain? | MythBusters

The 10% brain myth has been the foundation of every self-help book, motivational speech, and psychic power fantasy since the early 20th century — the claim that humans only actively use a tenth of their available brain capacity, leaving 90% dormant and waiting to be unlocked — and Kari, Tory and Grant decided to settle it properly by going to UCSF, consulting with a neurosurgeon about the most accurate way to measure brain activity, putting Grant through an electroencephalogram while he completed a battery of tests covering memory, calculation, decision making, and visual processing, and then putting Tory into a functional MRI scanner to get a more detailed picture of exactly what percentage of the brain is active at any given moment, because MythBusters never lets a myth this pervasive survive without a brain scanner pointed directly at it. Subscribe so you never miss an experiment:    / @mythbusterstvshow   Using science as their weapon and curiosity as their fuel, Hollywood special effects experts Adam Savage and Jamie Hyneman spent 14 seasons and 296 episodes testing the world's most popular myths, urban legends, and movie moments. From the Diet Coke & Mentos explosion to surviving an underwater car escape — if it can be tested, they'll test it. #MythBusters #AdamSavage #ScienceExperiments
