Nonassociative learning is considered simple because it depends on presentation of a single stimulus, but it likely reflects complex molecular signaling. To advance understanding of the molecular mechanisms of one form of nonassociative learning, habituation, for ethologically relevant signals we examined song recognition learning in adult zebra…

Early in life, infants possess an effective face-processing system which becomes specialized according to the faces present in the environment. Infants are also exposed to the voices and sounds of caregivers. Previous studies have found that face-voice associations become progressively more tuned to the types of association most prevalent in the…
