19 Amazing facts about human brain

What is human Brain?

The human brain is the centralized command giving organ for the human nervous system. Brain receives signals from the body's sensory organs such as skin and then give reponse to these organs with the help of neurons. Human brain is the complex organ of all the other organs.

Parts of Brain:

 Human brain has three major parts:

• Forebrain
• Midbrain
• hindbrain    

                           

      

   Amazing facts about human Brain:

1. Human brain is just 2% of the total body weight but it is the largest brain in all organisms.
2. Brain weighs about 1.5 kilograms.
3. Cerebrum is the most weight carrying part of brain and it  makes up 85 percent of the brain's weight.
4. Brain has the ability  to react on the situation immediately even faster then a supercomputer from the information coming from eyes and other sensory organs.
5. Brain contains about 100 billion microscopic cells which are called neurons and it would take you over     3,000 years to count them all. 
6. Human brain can generate electricity to power a lightbulb and this is amazing fact about the brain.
7. Human Brain can receive the information from the sensory neurons with a speed of 150 miles per hour. This happens when insect such as honey bee land on your skin and your eyes sense them and sends signal to brain and then brain response immediately and you shake the area so that honey bee fly off.  
8. Brain is the master of the body and without its permission no decision is taken.
9. The human brain constitutes more than 10 billion nerve cells and over 50 billion other cells.
10. The human brain is contain approximately 75 percent water, as well as fat and protein. When body is dehydrated the the brain functioning is also effected.
11. Brain needs glucose all the time for its proper functioning.
12. Brain consumes more energy about 20% of the total body's energy.
13. Brain release dopamine when we are in a happy mood and dopamine excites the neurons. when more dopamine release then we are more happy such as while lishtening music or watching something in which we are interested. As a result our body becomes habitual of this high dopamine situation and less dopamine is released while studying.Thats why students donot feel happy while studying.

Interesting point about Albert Einstein Brain

Einstein always said that a person who never made a mistake, he never tries to do something new. Einstein is considered the most intelligent person in the world.

Dr.Thomas Harvey stole the brain of Einstein after his death and he found that cerebral cortex part of the Einstein is different from normal human brain and it has the large number of neurons cells. Cerebral cortex is responsible for thinking and cognition. Thats why Einstein cognitive power was very good.
