Work

During the 60s, Torsten Wiesl and his colleague David Hubel established a detailed model of how the visual system works, from his studies on the cat’s visual cortex.
They explained, how the light is captured by the retina, then travels to the thalamus, and reaches the visual cortex, where the information is reassembled and contrasted with other areas of the brain.
They characterized the optic cortex as a organized area, where modules where present, and were groups of different types of neurons were specialized and coordinated in specific functions, like processing of contrast, orientation and patterns. They also explained that the ability to see develops in a critic period after birth.
