The effects of EA and the DRD2 antagonist sulpiride on anxiety-like behaviors induced by microinjection of the DRD2 agonist quinpirole in the BLA. A Schematic of EA treatment and drug injection and behavioral testing. B Diagram showing the cannulation location (left) and a representative coronal section of the BLA from a mouse brain showing the cannula tip upon injection (right). C The effect of treatment in each group on the PWTs. (n = 9 per group). D–F The effect of treatment in each group on anxiety-like behaviors in the EPM (D) and OFT (E–F). (n = 7–9 per group). G Representative diagram showing tracked movement and activity heatmaps from the EPM. H Representative diagram showing tracked movement and activity heatmaps from the OFT. Data are expressed as the mean ± SEM. Tukey’s post hoc test: *p < 0.05 comparison of the two groups
