Description: Many species-specific sensorimotor behaviors, such as speech in humans, emerge from the interplay between genetically defined developmental programs and sensory experience. How these processes interact during learning to shape motor circuits is not well understood. The zebra finch (Taeniopygia guttata), an oscine bird that learns to imitate the song of its tutor (usually the father), provides a uniquely tractable model for exploring this question. Song learning in zebra finches takes place during a discrete three-month period during which male juveniles progress from producing highly variable rudimentary sounds that are noisy and unstructured, to a highly stereotyped imitation of their tutor's song. Here I characterize learning-related changes in the functional connectivity within a motor cortex-analogue brain area (RA) that control song production.
