WebHubel and Wiesel used microelectrodes and modern electronics to detect the activity of individual visual neurons, using cats as their subjects. (The cats were not harmed by these experiments; indeed, their purring created vibration problems.)

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 ).
