Neural circuits underlying the performance of vocal communication signals in songbirds Jon Sakata, PhD Department of Biology, McGill University Sakata Songbird Lab Across a variety of species that use vocal signals for social communication, signalers alter the structure and content of their vocal signals depending upon the social context and audience. These vocal modifications have been hypothesized to increase the salience and interpretability of communication signals, but little is known about the neural mechanisms underlying such social influences on communication. In this talk, I will discuss my recent experiments examining the neural circuitry underlying the social modulation of song in songbirds. In particular, I will discuss the degree to which cellular activity in forebrain, basal ganglia, and midbrain circuits differs depending on the social context in which vocalizations are performed as well as the contribution of catecholamines to the social modulation of vocal performance. These experiments provide insight into general mechanisms underlying social influences on behavior and highlight the utility of songbirds for understanding neural mechanisms of communication and vocal motor control.
