The brain is the most complex part of the human body and something scientists continue to study and learn from each day. We've pulled together 5 interesting facts we bet you didn't know about your brain!

     

1. If our brains could record TV, they could store up to 300 million hours,
enough to keep your tv running for more than 100 years




2. If you stretched out all the white-matter in your brain,
you would have 100,000 miles (160,000 kms) of nerve fibres,
greater than 4 times the Earth’s circumference




3. A piece of brain tissue the size of a grain of sand
contains 100,000 neurons and 1 billion synapses.




4. The human brain is the only object of any
kind that can contemplate itself.




5. The total length of the nerve fibre network in the brain is
approximately 500,000 km, more than the distance
