Web26 jul. 2012 · Hubel and Wiesel began the modern study of development and plasticity of primary visual cortex (V1), discovering response properties of cortical neurons that distinguished them from their inputs and that were arranged in a functional architecture. Their findings revealed an early innate period of de … The Hubel and Wiesel experiments greatly expanded the scientific knowledge of sensory processing. The partnership lasted over twenty years and became known as one of the most prominent research pairings in science. In one experiment, done in 1959, they inserted a microelectrode into the primary visual cortex of an anesthetized cat. They then projected patterns of light and dark o…

WebHubel and Wiesel's Nobel prize winning work showed the importance of sensory experience in shaping neural connections during a sensitive period early in life. This was inspired by the 18th century notion that early visual deprivation (e.g., blindness at birth) results in brain changes that lead in turn to defective visual perception ( Wiesel, 1982 ).
