In support of such a finding, previous studies have observed enhanced consolidation of emotionally arousing material when compared with neutral material following cortisol or stress treatment (Buchanan & Lovallo, 2001; Cahill et al., 2003). [...] Previous studies (e.g., Buchanan & Lovallo, 2001; Kuhlmann et al., 2005) have further suggested that the effects of cortisol are similar for positive as well as negative material, which suggests that emotional arousal rather than valence is the critical aspect of the observed interactions. These observations are in accord with neuroimaging studies showing that the activity of the amygdala is associated with memory formation of arousing stimuli (Cahill et al., 1996; Canli et al., 2000), apparently independent of stimuli valence (Hamann et al., 1999; Kensinger & [Corkin, 2004).]

[Two previous studies have observed enhanced consolidation] of emotionally arousing material when compared with neutral material after cortisol or stress treatment (Buchanan and Lovallo, 2001; Cahill et al., 2003). [...] In our current study, as well as in previous studies (Buchanan and Lovallo, 2001; Kuhlmann et al., 2005), the effects of cortisol were similar for positive as well as negative material, which suggests that emotional arousal rather than valence is the crucial aspect of the observed interactions. These observations are in accord with neuroimaging studies showing that the activity of the amygdala is associated with memory formation of arousing stimuli (Cahill et al., 1996; Canli et al., 2000), apparently independent of stimuli valence (Hamann et al., 1999; Kensinger and Corkin, 2004).

Anmerkungen

The references for Canli et al. (2000), Hamann et al. (1999) and Kensinger & Corkin (2004) are all missing from Jm.

Nothing has been marked as a citation. The original source is only mentioned in passing - if at all: "Kuhlmann et al., 2005" cannot be found in the list of references. The reader needs to guess if this means "Kuhlmann, S., Kirschbaum, C., & Wolf, O.T. (2005a)" or "Kuhlmann, S., Piel, M., & Wolf, O.T. (2005b)".

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).
