The 5 Brain Myths You Still Believe

Описание: Most of what we think we know about the brain is wrong.

In this video, I debunk five of the most persistent brain myths: the idea that we only use 10% of our brains, that people are either “left-brained” or “right-brained”, that multitasking makes us efficient, that humans have only five senses, and that a bigger brain automatically means a smarter brain.

These myths are not just harmless trivia. They shape how we think about education, intelligence, creativity, productivity, and human potential. The real neuroscience is far more interesting: the brain is active, dynamic, integrated, sensory-rich, and astonishingly efficient.

As a Consultant Neurosurgeon, I spend my professional life working with the human brain at its most intimate level. The brain I encounter in the operating theatre bears very little resemblance to the simplified version that appears in popular mythology.
