Pharmacological functional magnetic resonance imaging studies have recently shown that this effect is dependent on β-adrenergic activation in the amygdala (Strange & Dolan, 2004; van Stegeren et al., 2005), thereby replicating the effects demonstrated in rats (McGaugh & Roozendaal, 2002; Roozendaal, 2002). However, the role of the amygdala in emotional memory retrieval is not as well understood (Taylor et al., 1998; Dolan et al., 2000; Smith et al., 2004; Strange & Dolan, 2004). More imaging studies are warranted that investigate the effects of stress or stress hormones on memory retrieval. The only study on this topic to date in humans observed a reduced blood flow in the right posterior medial temporal lobe following cortisol treatment (de Quervain et al., 2003).
