Abstract/Description: In this Dissertation, I detail how two vocal motor pathways (vocal motor pathway and anterior forebrain pathway) contribute to the vocal production in zebra finch adult song. I first describe a model of rapid dissolution and recovery based on partial damage to a primary vocal control region. Second I explore how recovery from destabilization requires auditory feedback and thus reflects a period of vocal plasticity much like vocal development where sensory feedback facilitates a transition from variable to stereotyped motor production. Thirdly, I test two models for the role of the anterior forebrain pathway in recovery from dissolution. I find that the anterior forebrain pathway largely contributes variable patterns of activity during adult vocal production and its ablation facilitates faster recovery. Finally, I explore the nature of the time-variant signal generated by the AFP and show that instead of global modulation across acoustic features, the AFP modulates the variance of specific features of song.
