Brain Usage Myth?


“We only use 10% of our brains.”


Ruling:
False. Misunderstood metaphor.

Analysis:
Our brains consist of cells which conduct nerve impulses through electrical and chemical signals, these are called neurons. Neurons do not fire at all times; however, that does not mean that inactive neurons are useless, nor that 90% of the 86 billion neurons that make up the human nervous system are permanently inactive.
