Research Summary
How does the brain generate social behavior? Successful social interaction requires the brain to receive and process sensory signals that communicate complex information and generate motor behavior fitting to the social context. My research examines social behavior from sensation to action, examining links between sensory and motor regions through the forebrain, and the role of these pathways in generating socially appropriate behavior. Key components of this network under investigation- the amygdala, basal ganglia, and bed nucleus of the stria terminalis- are similar across vertebrates in developmental origin, neurotransmitter types, and connectivity with sensory and motor systems. Though these regions have been most thoroughly studied in the auditory contexts of stress and threat detection, my primary interest is how they influence social interaction. I use African clawed frogs (Xenopus laevis), a well-established NIH model organism of social vocal communication, to examine how auditory information influences vocal performance. Research in my lab uses a variety of behavioral and physiological approaches to investigate the neurochemical mechanisms and neuroanatomical pathways involved in perceiving and processing social cues, and regulating social behaviors.
