optic nerve speed

human eye nerve overlayResearch from Penn’s School of Medicine on how the human eye communicates with the brain.

Earlier studies on vision have focused on what kind of information is sent from eye to brain. The Penn team wondered how fast and how much of that information is transmitted. Recording ‘spikes’ of electrical impulses, the human retina can transmit data at 10 million bits per second—Ethernet speeds, which reach 10 to 100 million bits per second.
