Social interactions have profound influences on what we learn and how we behave. For example, social interactions influence the magnitude and speed of speech learning as well as the structure and organization of speech. Despite the prevalence and importance of such social influences, little is known about the mechanisms by which social signals affect vocal learning and behaviour. My lab uses neurophysiological, immunocytochemical, and molecular tools to reveal how neuronal populations encode social signals and mediate social influences on vocal learning and control in songbirds. My research will provide insight into general principles underlying communication, social behaviour, and cognition as well as potential mechanisms underlying communicative, social, and cognitive disorders such as autism.
