What Is Brain??
http://www.at-bristol.org.uk/educati...mages/9076.jpg What is the brain? The human brain - 1.4 kg of the most amazing material on this planet. This soft warm piece of flesh allows you to think, walk, talk, learn, make friends, have emotions and know what it means to be alive. How many brain cells do I have? You have 100 000 million brain cells. Which animal has the biggest brain? A blue whale. It's brain weighs 6kg (and its body weighs 60 000). Humans have the largest brains in relation to their body size. What do all your brain cells do? They all connect to thousands of your other brain cells. Each part of your brain has a different job to do (smelling, seeing, speaking etc). All the brain cells are connected up to form a huge network. If you count the seconds since the dinosaurs were alive - that's how many brain connections you have. http://www.at-bristol.org.uk/educati.../1MVC-001S.jpg Does our brain change when we learn? Scientists think that every time you have a new thought or memory, you are making a new brain connection. Can I improve my memory? Absolutely. Your memory is like a muscle - the more you use it the better it gets. So try a daily exercise. Think of every single detail of something you did today. Your walk to school or work, a conversation or a lesson, or try to sum up every new thing you have learned today - faces, names, smells, places. http://www.at-bristol.org.uk/educati...mages/9089.jpg Can I learn to think quicker? Yes. As with anything, the more you do it the better you get. Try thinking of every word beginning with P, or all the animals you know. Doing crosswords, puzzles and riddles also flexes your brain and speeds up your thinking. How many new brain connections have you made reading this page |

السلام عليكم ورحمة الله وبركاته Thank you sister =\.Aya./= so much for this interesting topic full of information if you allow to me to add two simple information the ant has the biggest brain for its size compaired with other creatures the second info:never and never hit your head on any solid thing :Dthough; you will loose3600 brain cells and you can't recover them....becareful may ALLAH bless and protect you all السلام عليكم ورحمة الله وبركاته |
HELLO thnx sis 0*asma2*0 for ur nice informations its very important for people 2 know thank you may god bless u |
ma sha Allah great effort and avery nice topic let me add another thing for this marvellous part of the body it'a about the baby brain A baby's brain is a mystery whose secrets scientists are just beginning to unravel. The mystery begins in the womb -- only four weeks into gestation the first brain cells, the neurons, are already forming at an astonishing rate: 250,000 every minute. Billions of neurons will forge links with billions of other neurons and eventually there will be trillions and trillions of connections between cells. Every cell is precisely in its place, every link between neurons carefully organized. Nothing is random, nothing arbitrary. http://www.pbs.org/wnet/brain/episode1/images/pic1.jpg One way a newborn is introduced to the world is through vision. The eyes and the visual cortex of an infant continue to develop after birth according to how much stimulation she can handle. What happens to the brain when a baby is born with a visual abnormality? Infant cataracts pose an interesting challenge to scientists: How to remove the visual obstruction without compromising brain development. http://www.pbs.org/wnet/brain/episode1/images/pic2.jpghttp://www.pbs.org/wnet/brain/episod...1pullquote.gif When we are babies, our brains are more open to the shaping hand of experience than at any time in our lives. In response to the demands of the world, the baby's brain sculpts itself. Scientists have begun to understand how that happens, but as Neurologist Carla Shatz says, "There's a great mystery left. Our memories and our hopes and our aspirations and who we love all of that is in there encoded in the circuits. But we only have the barest beginnings of an understanding about how the brain really works." http://www.pbs.org/wnet/brain/images/spacer.gif |
thank you so much for this information really it is the first time I know all this info about the brain جزاكِ الله كل خير أختي آية..مع السلامة
