Intermittent social defeat stress induces psychostimulant cross-sensitization, as well as long-lasting social avoidance behavior. Previous data reveal heightened expression of AMPA receptor (AMPAR) GluA1 subunits in rat ventral tegmental area (VTA), which occurs concurrently with social stress-induced amphetamine (AMPH) cross-sensitization. These studies described herein examined whether VTA GluA1 AMPARs are important for the behavioral consequences of social stress and investigated the role of the infralimbic (IL) to VTA pathway in the induction of these responses.
