What is it about?
The study of social dominance interactions between animals offers a window onto the decision-making involved in establishing dominance hierarchies and an opportunity to examine changes in social behavior observed in certain neurogenetic disorders. Growing interest in social neuroscience requires the development and refinement of social behavior paradigms and novel analyses of the manner in which the neural activity in one brain may reflect the behavioral activity of self or of other, or the activity of each of two interacting individuals. This study documents an approach to analyze such interactions in a social dominance encounter between rodents.

Why is it important?
The neural activity associated with social dominance interactions is altered in some pathologies such as autism spectrum disorders (ASDs). The possible resolution of those deficits requires a better understanding of the basis of the behavior encoding. The calcium imaging technique provides an excellent opportunity to acquire a major knowledge about the role of the prefrontal cortex (PFC) in this encoding. Using this technique we have seen that the PFC is able to recognize not only the animal own behavior, but also the opposite's one. These correlates point to a more cognitive rather than a solely behavioral dimension of social interactions that needs to be considered in the design of neurobiological studies of social behavior.
