1. The human brain weighs 3 pounds.

2. Human brain has the capacity to generate approximately 23 watts of power when awake.

6. When the blood supply to the brain stops, it is almost after 8-10 seconds that the brain starts losing the consciousness.

7. The blood vessels that are present in the brain are almost 100,000 miles in length.

8. In early pregnancy, the neurons develop at an alarming rate of 250,000 per minute.

9. There are 100 billion neurons present in the brain.

10. As we grow older, we are unable to remember new things. According to the researchers in the US it is because the brain is unable to filter and remove old memories which prevent it from absorbing new ideas.
