Birdsong study could help human stutterers

Researchers at the Methodist Neurological Institute (NI) in Houston and Weill Cornell Medical College in New York City used functional MRI to determine that songbirds have a pronounced right-brain response to the sound of songs, establishing a foundational study for future research on songbird models of speech disorders such as stuttering, as reported today in Proceedings of the National Academy of Sciences U.S.A.

This is the first functional MRI study to determine how vocal sounds are represented within the brain of an awake zebra finch, a well-studied animal model of vocal learning. Because of many similarities between birdsong and human speech, this research could lead to a better understanding of the cause of stuttering and other speech problems.
