Humans have two brains - left one and right one

If you think you have one brain, no, you have two brains, the left one and the right one. They function independently and they communicate through corpus callosum or in the case of this person whose corpus callosum was cut - on a piece of paper!

The left hemisphere is responsible for the speaking and for the justification and reasoning of your actions and the right one is responsible for facial recognition. If the corpus callosum is cut information that the right hemisphere is receiving from the left eye could not be said, but it is there in the right brain. Now if the person is asked to draw what the left eye saw the right hemisphere will give exact orders what to draw. The right eye will signal the left hemisphere what is it and the person will be able to say it.
Just amazing!
