Your Amazing Brain !!!
Inside your head, there's a mass of wrinkly material weighing about 1.3 kg that governs everything you'll ever do. It gives you the ability to think, learn, create, and feel emotions while still allowing you to control every blink, breath, and heartbeat. It's so remarkable that renowned scientist James D. Watson once referred to the brain as “the most complex thing we have yet discovered in our universe.” This fantastic organ is your brain!

Your brain is more efficient and quicker than a supercomputer!
Imagine, your pet cat is on its way into the kitchen. She's about to place her foot on the hot burner. You just have a few seconds to make a decision. Your brain easily determines when, where, and at what pace you'll need to leap to stop her using the signals from your eyes. Then it instructs the muscles to contract. Your timing is perfect, and she is unharmed! Your brain's extraordinary capacity to download, process, and respond to the flood of information coming from your eyes, ears, and other sensory organs is unparalleled by any machine. That's awesome!
Your brain generates enough electricity to light a lamp!
Neurons are microscopic cells that make up about 100 billion in your brain. There are so many that counting them all will take over 3,000 years! It's because tiny chemical and electrical signals are racing between these neurons along billions of tiny neuron pathways that you dream, laugh, think, see, or move. Surprisingly, the brain never stops functioning. Your neurons produce and send more messages than all of the world's phones combined. While a single neuron produces very little electricity, all of your neurons together will generate enough energy to power a low-wattage light bulb. That's amazing!
Neurons send information to the brain at speeds of up to 240 kilometers per hour!
Suppose, your bare foot is stung by a bee. YIKES! This information is relayed to your spinal cord and brain at a rate of more than 240kmph by sensory neurons in your skin. Your brain then uses motor neurons to send the message back to your foot through your spinal cord – to quickly shake the bee off! This message can be relayed at speeds of up to 320kmph by motor neurons.
When you learn, the brain's structure changes.
Riding a bike can seem impossible at first, but it is quickly learned. How do you do it? Your brain sends ‘bike riding' signals through pathways of neurons over and over as you practice, creating new connections. In reality, your brain's structure changes every time you learn something new, as well as every time you have a new thought or memory.
Exercise can help you become smarter.
It's widely known that any activity that causes the heart to beat faster – such as running or participating in sports – is beneficial to your health and can even boost your mood. However, scientists have recently discovered that when you exercise, your body releases a chemical that makes your brain more likely to learn for a period of time. So, if you're stuck on a difficult homework task, go outside and run around for a bit, then return to the problem. You might find that you're a lot better at solving it!
