Скачать или смотреть Torsten Wiesel, Nobel Prize in Physiology or Medicine 1981: Official Nobel Lecture

Our vision works by the light around us being captured by a large number of light-sensitive cells located in the retinas at the back of our eyes. The light is converted into signals that are sent to the brain and there converted into visual impressions. Torsten Wiesel and David Hubel clarified how this process works during the 1960s: In the cerebral cortex signals are analyzed in sequence by cells with the specific tasks of interpreting contrasts, patterns, and movements. They also showed that this ability develops in children during the initial period after birth.

Torsten N. Wiesel held his Nobel Lecture on 8 December 1981, at Karolinska Institutet, Stockholm. He was presented by Professor David Ottoson, Member of the Nobel Committee for Physiology or Medicine.
