\section{Project Summary}  Animals are bombarded with ever changing visual, acoustic, chemical, tactile and social information as they navigate their environment. The central nervous system integrates these stimuli with internal information and past experience in order to guide adaptive behavioral decisions (i.e. approach or avoidance of a salient stimulus). Even controlled laboratory presentations of stimuli are not processed in the brain with static stimulus-response chains, but rather processing depends on the state of local and distributed brain networks. The network state is the emergent structure of ongoing activity in the brain: the response properties of one neural element (be it a single neuron, assembly of neurons or a brain region) is affected by the modulatory activity of the network it is embedded in \citeA{Bressler:2007ty}. \citea{Bressler:2007ty}.  Thus neural context (i.e. network state) is a determinative factor in sensory processing, influencing not only the perception of stimuli but also behavioral decision-making. Across vertebrates, social behavior is linked to a core network of brain regions called the social decision making network (SDMN). The SDMN is comprised of 11 brain regions, many of which are bidirectionally connected to one another and are sensitive to sex steroid hormones (SSH). They have been linked to a large variety of social and sexual behaviors \cite{OConnell:2011hk, Newman:1999ve, Crews:2003il, Goodson:2005gb}.
