With the help of a little singing bird, Penn State physicists are gaining insight into how the human brain functions, which may lead to a better understanding of complex vocal behavior, human speech production and ultimately, speech disorders and related diseases. Dezhe Jin, assistant professor of physics, is looking at how songbirds transmit impulses through nerve cells in the brain to produce a complex behavior, such as singing. Songbirds are particularly well suited for studying speech production and syntax -- the rules of syllable or word sequence -- because there are more similarities between birdsong and human speech than one may initially think. "We are not only interested in birds," Jin told attendees today (Mar.18) at the American Physical Society's March meeting in Portland, Ore. "We are ultimately interested in studying how the human brain works and better understanding ourselves." While many animals communicate vocally, songbirds are among the few th...
