Singing in the brain: Songbirds sing like humans

A songbirds’ vocal muscles work like those of human speakers and singers, finds a study published in the Journal of Neuroscience. The research on Bengalese finches showed that each of their vocal muscles can change its function to help produce different parameters of sounds, in a manner similar to that of a trained opera singer.

“Our research suggests that producing really complex song relies on the ability of the songbirds’ brains to direct complicated changes in combinations of muscles,” says Samuel Sober, a biologist at Emory University and lead author of the study. “In terms of vocal control, the bird brain appears as complicated and wonderful as the human brain.” Dr. Sober is a faculty member in the NS program.
