This piece will joyously expose some educational yet fun facts about the brain.

Did you know that the brain?…

Have billions of nerve cells

  • The human brain is made up of billions of nerve cells. Do you know if these cells create something called synapses?  This is a process whereby a billion neurons in the brain form trillions of connections.

Generate about 23 Watts of power 

  • An average human brain can generate enough electric power to light a bulb. Yes! That’s true. About twenty-three (23) watts of power can be generated by the human brain. It is safe to say that our brain’s got some superpower, thus our ability to think deeply and explore the creative part is usually limitless.

The brain is painless

  • The brain cannot feel any pain. It can only transmit and interpret the pains from the other parts/organs of the body. 

‘Fun fact: Brain surgeries can be carried out while the patients are awake’

  • Are you aware that the spinal cord is the brain’s messenger? The brain passes information to other parts of the body through the spinal cord.

Lack of Oxygen can cause brain damage

  • Brain cells can start dying if there is a lack of oxygen for even five (5) minutes.

Learning new things makes the brain better
