Is there such thing as a good cage? Happy gorillas, deft landscape architects and neurologists show us that there just might be. We go back to the late 1970s to relive the moment when zoos began to change—literally the moment that the modern zoo was born, as embodied by a few tentative steps of a gorilla named Kiki. That story, told by zoo director David Hancocks, architect Grant Jones, and gorilla keeper Violet Sunde. Then we'll hear about work done by neuroscientists Elizabeth Gould at Princeton and Fernando Nottebohm at Rockefeller who are looking into the brain to see the effects of living in a cage.
