Summary of Current Research

Social interactions are highly responsive to the emotional states of the social participants. Among animals, social interactions are a mainstay of the laboratory setting and in the natural environment. The ability of an individual to regulate its social interactions requires, at a minimum, two abilities.  First, the individual must be able to express signals that communicate one's own emotions, such as anger, fear, or indifference. Second, the individual must indicate that it can recognize the signals of others. Among animals, these abilities are crucial for survival within demanding wild environments. Among humans, deficits in these abilities are featured in  addiction, depression, schizophrenia, post-traumatic stress disorder, and pervasive developmental disorders, such as autism.    

To understand the regulation of social behavior, we study juvenile mice.  We examine how genetic and environmental variables influence the ability of juvenile mice to seek a social reward, to vocalize in response to changing social contexts, and to learn fear from observations of other mice that undergo environmental contingencies that promote fear learning. Genetic studies include the use of inbred strains and gene-targeted mice that are relevant to reward physiology and autism. Environmental studies focus on the effects of marine neurotoxins that contribute to pathologies in juvenile mouse social behavior.  We collaborate with The Marine Mammal Center in the Marin County headlands north of San Francisco to understand how early life brain lesions influence sea lion social behavior. We also employ brain-imaging techniques, such as glucose uptake and expression of immediate early genes, as well as metrics of systemic physiology, such as heart rate monitoring, to elucidate biological mechanisms of normal social behavior and its pathologies.
