David Hubel and the Visual Information Process

David Hubel

David Hubel, who helped revolutionize the understanding of visual information processing and shared the 1981 Nobel with a colleague for the work, has passed away at the age of 87.

Hubel’s work focused on understanding how the neurons of the retina communicate visual information to the brain. When he and Torsten Wiesel began their work in the 1950s it was still believed that the eyes projected visual images directly onto the cortex, as a movie is projected onto a screen.
Wiesel & Hubel essentially discovered that visual images perceived by the retina are first transformed into code and then transmitted to the brain. The brain then interprets that code to recreate the image.
