“…Several prior imaging studies have shown that amygdala plays a crucial role in recognition of most of the negative emotions in the face [34,35]. Our findings of impaired facial emotional recognition of negative emotions in AD patients is consistent with the results of neuroimaging and brain post-mortem studies which found the neuronal loss in the amygdala in the early stage of the Alzheimer's disease [10,19].…”

“…Statistical parametric maps (SPMs) were produced from linear contrasts of interest: each face category versus baseline (eg, angry4fixation) and all faces4fixation. We opted for this latter contrast to use in the group-level analyses for several reasons: (1) because of the application of high-pass filtering, condition (face expression)-specific effects are partly removed; (2) amygdala activation to the 'neutral' expressionless faces have been shown to also activate the amygdala to the same extent as emotional faces (Fitzgerald et al, 2006); and (3) IED subjects have been shown to mislabel 'neutral' faces as conveying negative emotions (Best et al, 2002). To test whole-brain voxel-wise effects, a full-factorial model was set up in SPM.…”

“…Unfortunately, we do not have selfreport ratings of saliency for each face stimulus and, unlike Cooper and Langton (2006), did not examine the effect of longer SOAs. Recent fMRI studies have reported, however, that activation in the amygdala is not specific to threat detection, but is activated for socially salient stimuli, even neutral faces (Fitzgerald et al, 2006;Klienhans et al, 2007;Sander, Grafmann & Zalla, 2003). Although amygdala activation cannot be measured by ERPs, presumed functional outputs of amygdala activation such as the ACC, medial and lateral prefrontal cortices and occipital cortex, are measurable at the scalp (Blair, Morris, Frith, Perrett, & Dolan, 1999;Morris, Friston, Buechel, Frith, Young, Calder, & Dolan, 1998;Vuilleumier & Pourtois, 2007).…”

“…A variety of emotional expressions (fear, disgust, angry, sad, neutral and happy) may or may not activate the amygdala (Fitzgerald et al, 2006). The strength of amygdala output signals to distinct neural circuits depends on the valence, meaning, and functional impact of the stimulus (Matthews, Mackintosh, & Fulcher, 1997;Springer, Rosas, McGetrick, & Bowers, 2007).…”
