Read an Excerpt

Jiggle your toes. Scratch your nose. Take a deep breath and yawn. Decide which is your favorite food. Try to remember the last time you ate it. Count the number of words in this sentence. Think about what you would like to do tomorrow. Then cup your hands around your head and feel the bones of your skull. Inside your skull is your brain. Your brain is the control center for everything you do.

Each second, millions of signals pass through your brain, carrying all kinds of messages. They bring news about what your body is doing and feeling. Your brain examines the messages, produces thoughts and memories, then plans what to do next. Signals go out from your brain to other parts of your body to enable you to read, run, laugh, breathe, say hello to a friend, or turn to the next page in this book. Try it!

Your brain, like the rest of your body, is made up of hundreds of billions of microscopic cells. Many of them are special messenger cells called neurons. Neurons carry signals back and forth from the brain to other parts of your body.

Billions upon billions of neurons are linked throughout your body in networks that make up the two main parts of your nervous system. The central nervous system, or CNS, consists of your brain and spinal cord. The network of nerves outside your brain is called the peripheral nervous system, or PNS.

Glial cells in the brain outnumber the neurons ten to one. Glial cells do not carry messages. They support the neurons by supplying nutrients and other chemicals, repairing the brain after an injury and attacking invading bacteria.

Introduction: The book The Brain is about how our brain and nerves in the brain work as one to make our bodies work. The author did a great job about explaining the nerves in the brain work. The way your brain work is about awesome. And just the way Seymour Simson tells you just how it all works together is so great. Description and summary of main points: One main point in this book is the Brain how and the ways it can work. Simson said "it takes half a second to send a message to the brain and back to feet." Two is that all your nerves in your Brain are all in one big bundle. I thought how he said it was pretty cool. Three is the way the all work as one to make our bodies move. It's different but every thing works as one! Evaluation: Most of the book was on how and why it hurt if you touch something hot. Half of your brain reeves the messages from lets say your hand. And the other half of your brain sends messages back out though your body. Conclusion: Mostly the book is just how the brain works and why it does what it does. And plus the way the nervous system in your brain works. But the brain and the nerves in the brain as one. Your final review: But you would have to read the book to really understand what is about. And just because it's an awesome/ great book! I love this book! And my friend said the cover is really neat.

This book shows many aspects of the brain. It starts off explaining about the millions of signals passing through your brain all the time. It talks about the bones and receptors in your skull and brain. I rated it 5 out of 5 because the pictures in this book are phenomenal and the information was accurate and very interesting to know. This book would be best for kids in fourth grade through sixth grade.
