Human: The World Within
Data Processing in the Brain
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.
