To test the role of AVP specifically, we used an shRNA viral construct to knock down AVP gene expression within the BNST of wild‐type male and female mice, using scrambled sequence virus as a control, and evaluated subsequent changes in social behaviours (social investigation, ultrasonic vocalization (USV), scent marking, copulation, and aggression), or anxiety‐like behaviours (elevated plus maze). This evidence concerns the gene AVP and Anxiety.
