Vocal communication signals are critical in social interactions across many species. In the zebra finch, a small, gregarious songbird, males produce learned vocal signals (‘songs’) during courtship interactions with females. Female zebra finches do not sing, but use songs to recognize individuals and select mates. Female song preferences are influenced by auditory and social experiences in development as well as adulthood. We still know little, however, about either the role of experience in shaping female preferences or the neural circuits involved in encoding song preferences. I will discuss recent data from my lab investigating the neural mechanisms of female song preferences and mating decisions and how they are modulated by social and auditory experience. The data will highlight the importance of developmental auditory experience and adult mating experience in tuning neural and behavioral responses to song as well as the role of midbrain dopaminergic activity allowing plasticity for these experiential changes through projections to the auditory cortex.
