You Only Use 10% of Your Brain

Neuroimaging reveals that over 90% of brain regions are active within any 24-hour period, directly debunking the 10% myth. This claim is 50% less accurate than 'Eating Fat Makes You Fat' (#4), as the brain uses about 20% of the body's energy even during sleep. Functional MRI scans show no dormant areas, with every region serving critical roles in motor control, memory consolidation, and sensory processing.
