A conversation with Fernando Nottebohm, PhD. Interviewed by Michael Eisenstein.

During the last 30 years, a number of revolutionary discoveries in the field of neuroscience have come from what was, at first, an unexpected direction: songbird research. Investigations into seasonal and sex-specific differences in birdsong development have led to important revelations about the impact of sex hormones on brain development and the hormonally controlled plasticity of brain structure, as well as the particularly surprising discovery that neurogenesis continues to occur in the adult brain (see Harding, p. 28). The work of Fernando Nottebohm is widely recognized as having played a key role in bringing these findings to light and thus forcing a general re-examination of established principles of neuroscience. Fernando Nottebohm is Dorothea L. Leonhardt Distinguished Professor at The Rockefeller University, and Director of The Rockefeller Field Research Center for Ethology and Ecology, a 1,200-acre facility located in Millbrook, NY, that provides researchers the opportunity to study behavior and brain function under natural conditions. Nottebohm's pioneering work on the neural control of birdsong has led to major discoveries with large impacts in the fields of animal behavior and neuroscience, and has made him one of the founders of neuroethology, the study of how the nervous system controls animal behavior. Nottebohm is a Member of the National Academy of Sciences, USA, and a Fellow of the American Association for the Advancement of Science and of the American Academy of Arts and Sciences. We had a chance to sit down with him to discuss his distinguished career working with laboratory birds.
