Songbirds show extensive neuroplasticity over the seasons in the song control system related to their song behavior. In this experiment we used resting state fMRI to asses plasticity in the auditory network. The fact that female starlings select mates based on song characteristics possibly indicate an increased relevance for auditory discrimination in breeding season compared to non-breeding season. In this study we investigated if this increased discrimination is reflected in an increased local functional connectivity (FC) within the major auditory areas.
