We bilaterally expressed opto-β2ARBLA/CaMKIIα in the BLA (Fig. 5a–d, Supplementary Figs 10a,b and 11) and photoactivated (5 s on, 5 s off) animals during two different yet widely used rodent anxiety-like behavioural models, the elevated zero maze (EZM) and the light–dark box (LDB)43, 44. This evidence concerns the gene CAMK2A and Anxiety.
