(Sept. 28, 2010)--Todd Troyer, assistant professor of neuroscience in the UTSA Department of Biology and a member of the UTSA Neurosciences Institute, has received a three-year, $400,898 grant from the National Science Foundation's Neural Systems Cluster to continue his research on how birds learn to sing. Troyer's findings will contribute to a better understanding of how the human brain functions during neurological disorders.

Although U.S. universities employ only a handful of songbird researchers, their findings are influencing how the research and clinical communities view neurological disorders such as obsessive-compulsive disorder (OCD) and Parkinson's disease. During OCD, patients are unable to switch off a brain circuit that produces a certain task. Understanding how a songbird's brain controls changes from one musical note to a different note is helping researchers form new hypotheses on how the human brain may get stuck repeating a single behavior.

Songbird researchers also have demonstrated that the basal ganglia circuits behave similarly in human and bird brains. In humans, the basal ganglia long have been known to regulate motor skills and learning. The circuit malfunctions in Parkinson's patients, who have difficulty starting or changing tasks. Songbirds use their basal ganglia during song practice and performance and to regulate song variability.

Troyer has spent a significant amount of time studying zebra finches, which learn to sing by mimicking their fathers. The process takes about three months to fine tune and results in a song unique to each finch. The new funding will allow Troyer to determine how a finch's brain sequences musical notes and how it controls changes from one note to a different note. Ultimately, he will map the bird's active brain cells to corresponding parts of its song.

Troyer also will repeat his research in adult birds. Using Bengalese finches, he will collaborate with University of California, San Francisco electrophysiologist Michael Brainard to record the activity of single brain cells as birds sing. They will analyze the variation in both brain activity and song output. These data then will be used to build computer models of how the brain activity is coordinated as the bird sings.

"It is extremely important to support basic science because we rarely know where the next advance is coming from," said Troyer. "Researchers didn't set out to make a link between song learning and neurological disorders. It's just something that happened after years of fundamental research. Given this type of unpredictability, there is great value in conducting general research. The knowledge it generates will surely help out in ways that are currently unknown."
