Co-winner of the Nobel Prize in Physiology or Medicine in 1981 for mapping the visual cortex
"If you hear about a scientist who appeals to your interests, look him or her up. Don't be shy... "
Hubel majored in physics at McGill University in Montreal, Quebec, and then became interested in medicine. He enrolled in McGill’s medical school, without ever having taken a biology course. In 1958, Hubel moved to Johns Hopkins and teamed up with Torsten Wiesel, a researcher from Sweden. The pair began almost immediately to make key discoveries about the visual cortex, which is the part of the brain involved in vision. A year later they moved to Harvard Medical School, continuing their experiments. Throughout the 1960s and 1970s, Hubel and Wiesel co-authored a series of ground-breaking papers on the visual cortex. They used microelectrodes and modern electronics to detect the activity of individual neurons, using cats as their subjects. (The cats were not harmed by these experiments; indeed, their purring created vibration problems.) Thanks to the work of Hubel and Wiesel, the visual cortex has become the best known part of the brain. They shared the Nobel Prize in 1981.
