With regard to unconditioned anxiety behaviors, unilateral intra-BLA infusions of THC produced an anxiogenic effect in rats measured using the elevated plus-maze (Rubino et al., 2008). In contrast, neither bilateral intra-BLA Win 55212-2, nor intra-BLA AM251 had any effect on locomotor behavior or anxiety measures in the open field assay (Ganon-Elazar and Akirav, 2009).
