The idea that humans only use 10% of their brain is a popular myth. In reality, we use virtually all parts of our brain.

Key Points:

• Neuroscience research shows that almost every region of the brain has a known function.
• Brain imaging techniques like fMRI and PET scans demonstrate activity across the entire brain, even during simple tasks.
• Different tasks activate different areas, but over the course of a day, nearly 100% of the brain is engaged.
• The brain is energy-intensive, using about 20% of the body's energy, which wouldn't make sense if 90% were unused.

Summary:

We use 100% of our brain -just not all at once. The brain is highly efficient, with different parts working together depending on the activity. If you'd like, I can share more about how specific brain regions function or debunk other common brain myths!
