You Have A Super Computer
Posted by Admin | Date 2016-04-19

Your kitten is on the kitchen counter. She's about to step onto a hot stove. You have only seconds to act. Accessing the signals coming from your eyes, your brain quickly calculates when, where, and at what speed you will need to dive to intercept 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 flood of information coming from your eyes, ears, and other sensory organs.

 

Your brain generates enough electricity to power a lightbulb.

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 zip around inside it every second like a supercharged pinball machine. Your neurons create and send more messages than all the phones in the entire world. And while a single neuron generates only a tiny amount of electricity, all your neurons together can generate enough electricity to power a low-wattage bulb.

 

Neurons send info to your brain at more than 150 miles (241 kilometers) per hour.

A bee lands on your bare foot. Sensory neurons in your skin relay this information to your spinal cord and brain at a speed of more than 150 miles (241 kilometers) per hour. Your brain then uses motor neurons to transmit the message back through your spinal cord to your foot to shake the bee off quickly. Motor neurons can relay this information at more than 200 miles (322 kilometers) per hour.

 

When you learn, you change the structure of your brain.

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, forming 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.

Certain activities such as studying a new language, exercising, and learning to juggle can increase gray matter. This is a tissue in the brain that is thought to help you process information. Many scientists believe that the more gray matter you have the faster your brain works.  

  

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 makes your brain more receptive to learning. 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.
