To address the contribution of nNOS‐mediated SNO‐gephyrin to anxiety‐like behaviors, lentivirus (LV)‐mediated gene transfer of constructs containing short hairpin RNA targeting nNOS (shRNA‐nNOS) was injected into BLA to reduce nNOS expression (Figure 5E,F; Figure S9A, Supporting Information). This evidence concerns the gene NOS1 and Anxiety.
