    The brain is mission control of the human body and the nervous system. Its 100 billion cells are processing data an incredible speeds. The brain coordinates not only the major functions of the body, but it also is the hub where information is interpreted and stored, and then turned into action.

    Data Processing in the Brain

    S1 E6 - 2m 43s

    All sight is translated into electrical impulses via the retina to the brain. The eye picks up information in the form of light. This light is instantaneously transformed into electricity, which shoots up to the brain. Once there, the electricity is decoded and formed into a picture. The information is traveling at speeds nearing 300mph, and the stream of data never stops.

    Pain is a phenomenon that is deeply intertwined with the brain and nervous system. When something is wrong with the body, signals travel to our brain as neural impulses. These impulses are then interpreted by the brain as pain, which is basically the body's signal to us that we need to fix something.
