Our brain is amazing

PHDComics explains why our brain is amazing: we have 86 billion cells in it, 20% of them are packed in the cerebral cortex (which is about 4mm thick) and which covers 2500 square centimeters, the axons span over 100 miles and they send the electrical signal with about 220mph.

It seems that the brain consumes 25 Watts of power and about 20% of the oxygen we need. Interestingly, it cannot feel pain, but it can perceive it. The brain does not have pain receptors. Cool thing to know when we finally move over to a machine Universe.

There are certainly many more things to note about the brain and I like to add one: it can fool itself.
