A Bird’s Song May Teach Us About Human Speech Disorders

*UCLA scientists identify 2,000 important genes*

Can the song of a small bird provide valuable insights into human stuttering and speech-related disorders and conditions, including autism and stroke? New research by UCLA life scientists and colleagues provides reason for optimism.
