The average weight of human brain is about 3 lbs or 1.3 to 1.4 Kgs.
The cerebrum is the largest part of the brain and makes up 85% of the brain’s weight.
The neocortex makes up about 76% of the human brain and is responsible for language and consciousness.
The human neocortex is much larger than in animals.
The total surface area of the cerebral cortex is about 2500 sq. cm
Your brain consists of a combination of 60% white matter and 40% gray matter and is about 75% water and 60% fat.
Your brain has between 50 and 100 billion neurons, with anywhere from 1,000 to 10,000 synapses for each neuron creating 1000 trillion connections … that’s 1,000,000,000,000 or a million million!
All of your neurons are fed by 100,000 miles of blood vessels that channel about 750ml of blood to your brain every minute!
Your brain uses approximately 20% of the total oxygen pumping around your body … and the same for blood.
All this neuronal activity generates between 10 and 23 watts of power – or enough energy to power a light bulb.

There are no pain receptors in the brain, so the brain can feel no pain even though it is where you actually experience pain in your body.
Your brain can process Information as slowly as 0.5 meters/sec or as fast as 120 meters/sec (about 268 miles/hr).
The old adage of you only use 10% of your brain is not true. Every part of the brain has a known function.
The brain can live for 4 to 6 minutes without oxygen, and then it begins to die. No oxygen for 5 to 10 minutes will result in permanent brain damage.
Unconsciousness will occur after 8-10 seconds after loss of blood supply to the brain.
The average number of thoughts that humans are believed to experience each day is 70,000.
Each time we blink, (about 20,000 times a day) our brain kicks in and keeps things illuminated so the whole world doesn’t go dark.
