The human brain weighs 3 pounds
It contains 60% fat and is one of the most common organs in the human body.
The human brain has the ability to generate about 23 watts of electricity upon waking.
The brain gets 20% of the total blood and oxygen produced in our body.
When the blood supply to the brain stops, it is after about 8–10 seconds that the brain begins to lose consciousness.
The brain is only able to survive for 5 to 6 minutes if it does not get oxygen after which it dies.
The blood vessels present in the brain are approximately 100,000 miles in length.
There are 100 billion neurons in the brain.
In early pregnancy, neurons develop at an alarming rate of 250,000 per minute.
As we grow older, we are unable to remember new things. According to researchers in the US this is because the brain is unable to filter and remove old memories that prevent it from absorbing new thoughts.
