Performance variability enables adaptive plasticity of 'crystallized' adult birdsong
Article Abstract:
The assumption that the noticeable trial-by-trial variations existing in the most practiced skills, enables trial-and-error learning, as the motor system generates variations and differentially keeps behaviors that produces better results, is analyzed for adult bengalese finch song. It is inferred that the residual variation in well learned skills is completely noise but significant motor exploration that support continued learning and optimum performance.

Contributions of an avian basal ganglia-forebrain circuit to real-time modulation of song
Article Abstract:
The functional contributions of basal ganglia-forebrain circuit to the control of song, a complex, learned motor skill is investigated. In songbirds, the anterior forebrain pathway (AFP) is a basal ganglia-forebrain circuit required for song learning and vocal plasticity but not for production of learned song.
