TLDR
Direct in vivo evidence of a differential neural response in the human amygdala to facial expressions of fear and happiness is reported, providing direct evidence that the humangdala is engaged in processing the emotional salience of faces, with a specificity of response to fearful facial expressions.Abstract:
The amygdala is thought to play a crucial role in emotional and social behaviour. Animal studies implicate the amygdala in both fear conditioning and face perception. In humans, lesions of the amygdala can lead to selective deficits in the recognition of fearful facial expressions and impaired fear conditioning, and direct electrical stimulation evokes fearful emotional responses. Here we report direct in vivo evidence of a differential neural response in the human amygdala to facial expressions of fear and happiness. Positron-emission tomography (PET) measures of neural activity were acquired while subjects viewed photographs of fearful or happy faces, varying systematically in emotional intensity. The neuronal response in the left amygdala was significantly greater to fearful as opposed to happy expressions. Furthermore, this response showed a significant interaction with the intensity of emotion (increasing with increasing fearfulness, decreasing with increasing happiness). The findings provide direct evidence that the human amygdala is engaged in processing the emotional salience of faces, with a specificity of response to fearful facial expressions.read more

Integrating Face and Voice in Person Perception
TL;DR: In this paper, the authors review behavioural and neuroimaging studies of face-voice integration in the context of person perception and find evidence for interference between facial and vocal information during affect recognition or identity processing.

TL;DR: The results suggest that acute administration of antidepressant drugs may affect neural processes involved in the processing of social information, and may represent an early acute effect of SSRIs on social and emotional processing that is relevant to their therapeutic actions.

Implicit Trustworthiness Decisions: Automatic Coding of Face Properties in the Human Amygdala
TL;DR: It is suggested that the amygdala automatically categorizes faces according to face properties commonly perceived to signal untrustworthiness, which is better predicted by consensus ratings of trustworthiness than by an individual's own judgments.

Emotional Responses to Pleasant and Unpleasant Olfactory, Visual, and Auditory Stimuli: a Positron Emission Tomography Study
Jean-P. Royet,David H. Zald,Rémy Versace,Nicolas Costes,F. Lavenne,Olivier Koenig,Rémi Gervais +6 more
TL;DR: It is suggested that pleasant and unpleasant emotional judgments recruit the same core network in the left hemisphere, regardless of the sensory modality, which suggests a superior potency of emotionally valenced olfactory over visual and auditory stimuli in activating the amygdala.

Event-related potentials of emotional memory: encoding pleasant, unpleasant, and neutral pictures.
Florin Dolcos,Rooberto Cabeza +1 more
TL;DR: The subsequent memory effect at centroparietal electrodes was greater for emotional pictures than for neutral pictures during an early epoch, which suggests that emotional information has privileged access to processing resources, possibly leading to better memory formation.

TL;DR: A general technique that facilitates nonlinear spatial (stereotactic) normalization and image realignment is presented that minimizes the sum of squares between two images following non linear spatial deformations and transformations of the voxel (intensity) values.

Impaired recognition of emotion in facial expressions following bilateral damage to the human amygdala.

TL;DR: Findings suggest the human amygdala may be indispensable to recognize fear in facial expressions, but is not required to recognize personal identity from faces, and constrains the broad notion that the amygdala is involved in emotion.
