Auditory-motor interactions are critical to a wide range of behaviors, including those necessary to vocal communication and musical performance.  The critical role of auditory experience in the normal development of certain complex behaviors, such as human speech or birdsong, indicates that auditory experience must instruct the vocal motor system.  Furthermore, many forms of sensorimotor integration, including those important to the acquisition and maintenance of learned behaviors, are thought to be facilitated by motor to sensory interactions.  I will describe studies in both songbirds and mice that delineate circuits that convey information between motor and auditory regions, explore their role in vocal learning, and detail how they function to modulate auditory activity during a variety of movements, including vocalization.
