CAMK2A and Anxiety: Similarly, using mice injected with rAAV-CaMKIIa-hM4D(Gi)-EGFP-WPRE-pA, rAAV-CaMKIIa-hM3D(Gq)-mCherry-WPREs, rAAV-CaMKIIa-EYFP-WPRE-pA into the BLA (Figure 4A), we performed the open field (Figures 5A,B) and the elevated plus maze experiment (Figures 5E,F) to evaluate anxiety-like behavior after administration of CNO.
