چکیده
A neuroimaging study in monkeys has shown that separate regions of the amygdala are responsive to facial expression and gaze/head orientation.

Neurocognitive mechanisms of gaze-expression interactions in face processing and social attention.
The face conveys a rich source of non-verbal information used during social communication. While research has revealed how specific facial channels such as emotional expression are processed, little is known about the prioritization and integration of multiple cues in the face during dyadic exchanges. Classic models of face perception have emphasized the segregation of dynamic vs. static facial...
متن کاملIntegration of gaze direction and facial expression in patients with unilateral amygdala damage.
Affective and social processes play a major role in everyday life, but appropriate methods to assess disturbances in these processes after brain lesions are still lacking. Past studies have shown that amygdala damage can impair recognition of facial expressions, particularly fear, as well as processing of gaze direction; but the mechanisms responsible for these deficits remain debated. Recent a...
متن کاملFacial-Expression and Gaze-Selective Responses in the Monkey Amygdala
The social behavior of both human and nonhuman primates relies on specializations for the recognition of individuals, their facial expressions, and their direction of gaze. A broad network of cortical and subcortical structures has been implicated in face processing, yet it is unclear whether co-occurring dimensions of face stimuli, such as expression and direction of gaze, are processed jointl...
متن کاملMEG Evidence for Dynamic Amygdala Modulations by Gaze and Facial Emotions
BACKGROUND Amygdala is a key brain region for face perception. While the role of amygdala in the perception of facial emotion and gaze has been extensively highlighted with fMRI, the unfolding in time of amydgala responses to emotional versus neutral faces with different gaze directions is scarcely known. METHODOLOGY/PRINCIPAL FINDINGS Here we addressed this question in healthy subjects using...
متن کاملAmygdala processing of social cues from faces: an intracrebral EEG study.
The amygdala is a key structure for monitoring the relevance of environmental stimuli. Yet, little is known about the dynamics of its response to primary social cues such as gaze and emotion. Here, we examined evoked amygdala responses to gaze and facial emotion changes in five epileptic patients with intracerebral electrodes. Patients first viewed a neutral face that would then convey social c...
