Neural mechanisms of vocal production in songbirds

Recent reports have described peripheral and central mechanisms of vocal production in songbirds. Respiratory patterning, individual syringeal muscles and the two syringeal halves have been shown to make specific contributions to learned vocalizations. New information on the function and organization of central pathways suggests how these production mechanisms may be controlled. The results are opening new avenues for further work on how acquired motor patterns are represented in this system.
