TLDR
A role for the amygdala in processing emotional stimuli that extends beyond negative and fearful stimuli is demonstrated, and arousal level is clearly demonstrated to modulate the amygdala response.Abstract:
Human lesion and functional imaging data suggest a central role for the amygdala in the processing of negative stimuli. To determine whether the amygdala's role in affective processing extends beyond negative stimuli, subjects viewed pictures that varied in emotional content (positive vs negative valence) and arousal level (high vs low) while undergoing functional magnetic resonance imaging. Amygdala activation, relative to a low arousal and neutral valence picture baseline, was significantly increased for both positively and negatively valenced stimuli and did not differ for the two valences. There were no laterality effects. Whereas arousal level appeared to modulate the amygdala response for negative stimuli, all positively valenced pictures (both high and low in arousal) produced significant amygdala responses. These results clearly demonstrate a role for the amygdala in processing emotional stimuli that extends beyond negative and fearful stimuli.read more

The Neurocircuitry of Fear, Stress, and Anxiety Disorders
TL;DR: Additional research will be needed to clarify the exact role of each component of the fear circuitry in the anxiety disorders, determine whether functional abnormalities identified in the Anxiety disorders represent acquired signs of the disorders or vulnerability factors that increase the risk of developing them, and use functional neuroimaging to predict treatment response and assess treatment-related changes in brain function.

The human amygdala and the emotional evaluation of sensory stimuli.
TL;DR: Specific conclusions and hypotheses include that the amygdala activates during exposure to aversive stimuli from multiple sensory modalities, and activation of the amygdala is associated with modulation of motor readiness, autonomic functions, and cognitive processes including attention and memory.

Gender Differences in Emotion Regulation: An fMRI Study of Cognitive Reappraisal:
TL;DR: Using functional magnetic resonance imaging, male and female participants were asked to use a cognitive emotion regulation strategy (reappraisal) to down-regulate their emotional responses to negatively valenced pictures, and gender differences emerged.

Looking at pictures: affective, facial, visceral, and behavioral reactions
TL;DR: Responsibility specificity, particularly facial expressiveness, supported the view that specific affects have unique patterns of reactivity, and consistency of the dimensional relationships between evaluative judgments and physiological response emphasizes that emotion is fundamentally organized by these motivational parameters.
