The Human Brain: Why do we like it?

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.

Welcome into the human brain.
