COOL FACTS ABOUT THE BRAIN

You carry around a three-pound mass of wrinkly material in your head that controls every single thing you will ever do. From enabling you to think, learn, create, and feel emotions to controlling every blink, breath, and heartbeat - this fantastic control centre is your brain. It is a structure so amazing that a famous scientist once called it “the most complex thing we have yet discovered in our universe.”

Your brain generates enough electricity to power a light bulb.

Your brain contains about 100 billion microscopic cells called neurons - so many it would take you over 3,000 years to count them all. Whenever you dream, laugh, think, see, or move, it’s because tiny chemical and electrical signals are racing between these neurons along billions of tiny neuron highways. Believe it or not, the activity in your brain never stops. Countless messages fly around inside it every second! Your neurons create and send more messages than all the phones in the entire world.

Riding a bike seems impossible at first. But soon you master it. How? As you practice, your brain sends “bike riding” messages along certain pathways of neurons over and over, creating new connections. In fact, the structure of your brain changes every time you learn, as well as whenever you have a new thought or memory.

Exercise helps make you smarter.

It is well known that any exercise that makes your heart beat faster, like running or playing basketball, is great for your body and can even help improve your mood. But scientists have recently learned that for a period of time after you’ve exercised, your body produces a chemical that stimulates your brain to learn. So if you’re stuck on a homework problem, go out and play a game of soccer, then try the problem again. You just might discover that you’re able to solve it.

Your brain is faster and more powerful than a supercomputer.

Your cat is on the kitchen counter. She’s about to step onto a hot stove. You have only seconds to act. With the signals coming from your eyes, your brain quickly calculates when, where, and at what speed you will need to make a move to save her. Then it orders your muscles to do so. Your timing is perfect and she’s safe. No computer can come close to your brain’s awesome ability to download, process, and react to the information coming from your eyes, ears, and other sensory organs.
