Song and the limbic brain: a new function for the bird's own song.
The neurobiological investigation of the avian song system has largely focused on the unique neural features of vocal control systems that contribute to learned motor patterns in songbirds. The role of emotion has been disregarded in developing a theory of song learning and performance. Here we review emerging evidence in support of Darwin's observation that vocal communication is emotional expression. We propose that neural pathways mediating emotional state remained integrated with the vocal control system as forebrain vocal control pathways evolved to support learned communication patterns. Vocalizations are therefore both a motor component of an emotional state and can influence emotional state via sensory feedback during vocal production. By acknowledging the importance of emotion in vocal communication, we are proposing that the song system and limbic brain are functionally linked in the production and reception of song.
