Do you know that human has something amazing and powerful inside his body? It weighs about 1.4 kilograms in your head. It is called brain. The human brain makes up about 2% of a human's body weight. It contains about 100 billion nerve cells (gray matter) and millions of nerve fibers (white matter).
Anatomy of The Human Brain
Forebrain
It is made up of cerebrum, thalamus, hypothalamus and pineal gland among other features.
Midbrain
It is composed of a portion of the brainstem and located near center of the brain.
Hindbrain
It consists of the remaining brainstem as well as cerebellum and pons.
Human Brain Facts
Brain control everything that we do, such as enabling you to think, eat, walk, cry, even blink, breath and many others. Brain also enable we to feel emotion like happy, sad, angry, tired, bored and so on.
Computer acts like the brain, but our brain is faster and much more powerful than a supercomputer. No computer in this world can get close to the ability of our brain to process and react to many information from our skin, eyes, ears, nose and other sensory organs.
Our brain's activity never stop even if we are sleeping. That's why we are dreaming in most of our sleep. And of course, we need to dream. The brain processes and and reacts to billions of messages from outside of body. A single neuron generates only a tiny amount of electricity, but all neurons together can generate enough electricity to power a low-wattage bulb.
The structure of our brain changes every time we learn. Can you play a skateboard? If you can't, it seems impossible to play, and it looks so difficult to do. But if you try to practice, practice and practice again, of course you will be good in skateboarding. Why? At first, your brain sends message that you can't play skateboarding. As you practice, your brain sends "skateboarding" message along certain pathways of neurons over and over, forming new connection.
