Research Description

Our research focuses on a network of brain regions that regulates social behavior in all vertebrates, although we work mostly with songbirds, since they provide us with opportunities to address questions that are difficult or impossible to address in other taxa. For instance, the estrildid finch family offers us the virtually unique ability to determine how neural and motivational processes have evolved in relation to sociality, as defined by species-typical group sizes, because we can identify species that  display massive variation in group sizes while still being closely matched in other aspects of behavior and ecology. We are currently working with five species of estrildid finches, including species that live in territorial pairs, small groups, or large groups that occasionally contain thousands of individuals.

Much of our work on sociality has focused on the nonapeptides vasotocin and mesotocin, which are homologues of the mammalian neuropeptides vasopressin and oxytocin. We have identified anatomical and functional properties of nonapeptide circuits that closely match species differences in behavior, and have further shown that nonapeptide systems can be manipulated to influence an individual's choice of group size, without simultaneously influencing that individual's decision to be social.

Our behavioral work is coupled with comparative neuroanatomical studies, which provide important information about how the social brain has evolved across all vertebrate taxa, and how we can compare our data on brain networks to other taxa, based on the identification of shared features. These anatomical approaches to homology are combined with a variety of functional approaches that allow us to establish the behavioral properties of specific brain regions and neurochemical systems. Our work has demonstrated a surprisingly strong degree of conservation in the  social behavior circuits of the basal forebrain and midbrain across the vertebrate classes, suggesting that our work in birds and fish should be informative for a broad range of species, including mammals.
