Dissociable neural responses to facial expressions of sadness and anger.
Previous neuroimaging and neuropsychological studies have investigated the neural substrates which mediate responses to fearful, disgusted and happy expressions. No previous studies have investigated the neural substrates which mediate responses to sad and angry expressions. Using functional neuroimaging, we tested two hypotheses. First, we tested whether the amygdala has a neural response to s...
متن کاملNeural Responses to Rapid Facial Expressions of Fear and Surprise
Facial expression recognition is mediated by a distributed neural system in humans that involves multiple, bilateral regions. There are six basic facial expressions that may be recognized in humans (fear, sadness, surprise, happiness, anger, and disgust); however, fearful faces and surprised faces are easily confused in rapid presentation. The functional organization of the facial expression re...
متن کاملTask instructions modulate neural responses to fearful facial expressions.
BACKGROUND The amygdala, hippocampus, ventral, and dorsal prefrontal cortices have been demonstrated to be involved in the response to fearful facial expressions. Little is known, however, about the effect of task instructions upon the intensity of responses within these regions to fear-inducing stimuli. METHODS Using functional magnetic resonance imaging, we examined neural responses to alte...
متن کاملAsymmetric facial expressions: revealing richer emotions for embodied conversational agents
In this paper, we propose a method to achieve effective facial emotional expressivity for embodied conversational agents by considering two types of asymmetry when exploiting the Valence-Arousal-Dominance representation of emotions. Indeed, the asymmetry of facial expressions helps to convey complex emotional feelings such as conflicting and/or hidden emotions due to social conventions. To achi...
متن کاملExplorer Risk for depression and neural responses to fearful facial expressions of emotion
Background: Depression is associated with neural abnormalities in emotional processing. Aims: This study explored whether these abnormalities underlie risk for depression. Methods: We compared the neural responses of high-risk and low-risk never-depressed volunteers during the presentation of fearful and happy faces using fMRI. Results: High-risk volunteers demonstrated linear increases in resp...
