Chapter 1: Your Brain Is Magic Grab something to write with and something to write on so when you see this symbol, you can play along with the activities and games in this book! CHAPTER 1 YOUR BRAIN IS MAGIC THE HUMAN BRAIN IS A mystery and a marvel. And maybe a little bit magical.* It tells our bodies what to do, consciously and unconsciously. It stores our thoughts and memories, regulates our emotions, and, every once in a while, comes up with really great ideas like antibiotics or waffle cones. MAGICAL (adjective): having the power to make impossible things happen; able to create things, including illusions, without the viewer knowing how. Much like when you practice baseball or the piano, every time you use your brain, you''re improving it. For example, look at the earlier drawing. What do you see? Pretend you had to describe it to someone who couldn''t see it.
What would you tell them? Would you tell them half the drawing was in black-and-white and the other half was in color? Would you mention the sketches and numbers on the left side and the colorful splatters that look like paint on the right? Does the illustration remind you of anything? If you''re thinking "a brain," you''re right. It was meant to look like a human brain. Did any shapes stand out to you? Did you find the same shape on both sides? If you saw the two stars, good for you! Your brain is tuned in to both details and patterns. If you didn''t, go look for them now. Scientists used to believe that the brain you were born with was the brain you were stuck with and that some people were just born with smarter brains. But as people lived longer, healthier lives and technology advanced, scientists were able to learn more about the human brain. And they discovered some startling things. Such as the brain can heal itself.
Or that it can make new pathways and rewire connections. And that it never stops growing. The brain''s ability to adapt and change is called "plasticity."* We can improve our brain''s function at any time in our lives, for all of our lives. The more you engage your brain, the quicker, smarter, and more powerful it will be. Which is helpful not just for your future--getting a job or following your passion--but also in the present. A better, faster brain can help you right now. It can help you do better in school, have better friendships, be a better judge of situations, and negotiate better deals with the adults in your life (like later bedtimes or a larger allowance).
A better, faster brain can help keep you safe, help you solve difficult problems, and help you see what everyone else may have missed. "PLASTIC" as a noun refers to the material used to make video game controllers and water bottles. "Plastic" the adjective means "capable of being molded." BRAINY KIDS In 1905, an eleven-year-old named Frank Epperson was in his San Francisco backyard making his favorite drink--flavored powder stirred into water--when his mother called him inside. He set his cup down and forgot all about it. There was an unseasonal frost overnight, and the next morning Frank found his cup had completely frozen, the stirring stick standing straight up in the colored ice. He tipped the cup upside down, removed it, held the stick, and licked the delicious fruity icicle. He realized other kids might like to do the same, so he intentionally began freezing his flavored water in small cups with sticks and called them "Epsicles.
" Today the company he started sells two billion "Popsicles®" a year.1 When Hannah Taylor was five years old, she saw something countless other people had seen before her: a homeless man eating out of a trash can. Instead of just shrugging it off though, Hannah decided to do something about it. Three years later, she founded the Ladybug Foundation to raise awareness and funds for the homeless community. She became a voice for the homeless, speaking to crowds of sixteen thousand people at a time, and so far, she''s raised $2 million to help the cause.2 When twelve-year-old Jessica Maple''s grandmother''s house was robbed, she was told by police that since they found no signs of forced entry, the burglar was someone who had used a key to get in. Jessica did her own detective work, though, and discovered a broken window and fingerprints the police had missed in the attached garage. She then thought about what the criminals would do with the stuff they stole and decided they might try to sell it for money.
She visited a local pawnshop and found some of her grandmother''s belongings there. When she told the police, they were able to interview the shop owner about who had sold them the items, and the suspects were arrested.3 What did these three kids have in common? They all saw something everyone else had missed. Want to be the hero in your own life, for your family, or for your community? You don''t need superpowers, just a supercharged brain. Supercharging your brain is easy, and anyone--I mean anyone --can do it. It doesn''t matter where you go to school or how many books you''ve read. It doesn''t involve memorizing or math. All it takes to increase your brain''s capacity for thinking and problem solving, to help you become the next inventor or crime solver or great humanitarian, is three simple steps: LEARN TO SEE LEARN TO THINK ABOUT WHAT YOU SEE LEARN TO TALK ABOUT WHAT YOU SEE I''m sure you''re thinking, as I once did, "But I already know how to see! I''ve been doing that since I was born!" Followed by, "And anyway, I see with my eyes, not my brain.
" It turns out that our eyes are actually part of our brain, and the eye and the brain work together in ways we probably never thought about. Let me explain. You''ve no doubt learned, from the science teacher and from feeling them with your finger, human eyeballs are round and made up of many parts. There''s the pupil--the black circle--and the iris--the colored circle--that work together to control the amount of light let into the eye. Then there''s the retina, a thin layer of tissue that covers the back of the eye and converts images into signals for our brain to organize. The retina is a complicated structure more like a computer than a simple pathway to the brain.4 In fact, it is the brain. (So, technically, when an optometrist looks at your retina during an eye exam, they''re looking at your brain!) When we engage our visual processing system, we''re using a full 25 percent of our brain and more than 65 percent of all our brain pathways.
5 So, in reality, we don''t "see" with our eyes; we see with our brain. USE IT OR LOSE IT Our ability to see and make sense of what we see relies on the brain''s incredible processing power--a power that depends entirely on the connections in our brains. Scientists have discovered that when we stop flexing our mental "muscles," their speed and accuracy decrease dramatically.6 Since our brain controls every function of our body, any slowdown in neural* processing, aka how our brain processes information, will cause a delay in the body''s other systems, including how we react to what we see. While slower reflexes and forgetting things are associated with old age, they can also be the result of not exercising our brains enough. Fortunately, the opposite is also true. Since our brains never stop making new connections, no matter how old we are, we can keep them fast and sharp by continually engaging them. Researchers have found that stimulating our brains in a variety of ways--from studying something new to reading about a concept that makes you think about things in a different way--will increase growth in brain tissue, even for the very oldest humans.
7 If you want to still be able to drive a car, play video games, and remember the lyrics to your favorite song when you''re one hundred years old, never stop training your brain. Want to flex your brain right now? The drawing on page 3 isn''t just a representation of the brain with all its "wrinkles"--technically the grooves are called "sulci" and the ridges are "gyri"--it''s also a maze! Actually, two mazes. Turn back and see how fast you can move through the LEFT side of the brain maze starting from the opening at the bottom (the brain stem) to the black star outline. Want to feel even smarter? Dare someone older than you to solve the RIGHT side of the maze and see how long it takes them. Come back here when you''re done. "NEURAL" refers to any part of the nervous system, which is made up of the brain, spinal cord, and nerves. Did you notice anything about the right maze? That wasn''t a printing error: if you start at the opening on the bottom right, you can''t get to the solid black star. at least, not if you stay inside the lines.
Did you read any instructions that said you had to stay inside the lines? I didn''t. Who is to say we can''t cross the line to get to the star? What if we drew a bridge over one of the lines? Or grabbed a frog to hop us over? Grab a piece of paper to draw three ways you could jump over this solid line: No matter how we e.
