investigating how such evaluations are carried out: like humans, songbirds memorize vocal sounds based on auditory experience with vocalizations from adult tutors.\u00a0 During sensorimotor learning, juvenile songbirds compare their own vocalizations to the tutor memory (the goal behavior) and refine their motor program accordingly.\u00a0 My project uses this model to address a fundamental

in songbirds serves as a powerful model for investigating mechanisms of motor skill learning because, like humans, juvenile songbirds learn this complex motor skill from an adult tutor during a sensitive period of development.\u00a0 Vocal learning in juvenile songbirds is mediated by parallel loops that traverse cortex, basal ganglia, and thalamus.\u00a0 The output of sensorimotor processing through these recurrent cortico-basal ganglia circuits is conveyed to vocal motor cortex, whose neurons directly drive vocal motor output.<\/p>\n<p><a
