Neurobiological Correlates of Social Status
Animals of dominant, sub-dominant and subordinate status exhibit different neurobiological features. These differences likely are related to the differential requirements of animals of each rank in behaviors including social cognition, spatial cognition, feeding, drinking, activity, sleep, aggression, social reward etc. An important step to understanding how the brain facilitates status-specific behavior is to characterize how variation in key neurobiological markers is associated with social status. In our current work, we are taking a more explorative approach to investigate brain gene expression profiles of mice varying in social status. Using Tag-based RNA-Sequencing (Tag-Seq) we have identified genes and gene networks that are differentially regulated between dominant and subordinate male mice in both the forebrain and midbrain.
