Brain power!

How powerful is your brain?

Inside your head is a jelly-like organ that controls everything you do. Without it, you wouldn't be able to think, run, dance or even breathe. But what makes your brain so special?

Your brain is like a powerful computer. It stores memories and controls how you move, breathe, think and react. Compared to other mammals about the same size as you, you have a big brain.

Your brain has lots of folds and wrinkles. The wrinkles increase the area of your brain, making lots of space for you to make connections between brain cells. More connections equal more brain power!

Here are our top five brain facts:

  1. When you're awake, your brain generates enough electricity to power a lightbulb.
  2. You have the same number of brain cells at birth as you do in adulthood. As you learn and store memories, these brain cells grow and you make new connections between them.
  3. Your brain makes up 2% of your body's weight, but uses 20% of your body's energy.
  4. The left side of your brain controls the right side of your body. The right side of your brain controls the left side of your body.
  5. James Watson, a famous scientist, once said the brain is "the most complex thing we have yet discovered in our universe."
