What Is Brain??

[آيـــه]

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.

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.

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.
