John Kirn, professor of biology, professor and chair of the neuroscience and behavior program, in May published an article in the Journal of Neuroscience on neurogenesis in songbirds. He recently spoke about his research on WNPR public radio and in The Hartford Courant. Q: Professor Kirn, you study the neuroscience behind song learning and production in zebra finches. Please tell us about your research, and the surprising findings to come out of your most recent work. A: I’m interested in the normal functions of adult neurogenesis—the continual addition and replacement of neurons. This happens to a limited extent in humans but…
