Living in noisy colonies, songbird vocal learning requires individuals to differentiate self-generated vocalizations from other sound sources to accurately match the learned song template. However, neurons responding to vocal output have not been identified. This study identifies neurons in the auditory forebrain of zebra finch that specifically responded to either song or playback perturbations, suggesting the existence of a computational error-checking function in the forebrain auditory areas.
