Around 100 billion neurons capable of 100 trillion calculations per second in only 1,195 cm3, weighting 1.5 kg, using 20% of our total daily energy along 162,500 km of connected “cables” processing 36,800 trillion bits of information per second. It is 2% of your body’s weight, but requires 20% of your oxygen supply and 20% of your blood flow.
The human brain is a huge calculator. As a matter of fact, the human brain is the most complex computational system ever known.
Computational is used here to describe the functioning of the brain since it deals with information and makes calculations out of it, it differs from computer in its uniqueness: while a computer treats only one information at a time, our brain treats them all together.
Welcome into the human brain.
