Neural processing of emotional faces requires attention.
Attention gates the processing of stimuli relatively early in visual cortex. Yet, existing data suggest that emotional stimuli activate brain regions automatically, largely immune from attentional control. To resolve this puzzle, we used functional magnetic resonance imaging to first measure activation in regions that responded differentially to faces with emotional expressions (fearful and hap...
متن کاملEvent-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces
Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...
متن کاملDisrupted neural processing of emotional faces in psychopathy.
Psychopaths show a reduced ability to recognize emotion facial expressions, which may disturb the interpersonal relationship development and successful social adaptation. Behavioral hypotheses point toward an association between emotion recognition deficits in psychopathy and amygdala dysfunction. Our prediction was that amygdala dysfunction would combine deficient activation with disturbances ...
متن کاملNeural Basis of Event Words
On some accounts, word-meanings are organized in the human-brain according to their sensory-motor attributes. We tested an alternative hypothesis: word-meanings are neuroanatomically dissociable along abstract conceptual dimensions (entities vs. events). We measured brain activity in the left middle temporal gyrus (lMTG), a brain region that has previously been shown to respond more to verbs th...
متن کاملProcessing of emotional faces in social phobia
Previous research has found that individuals with social phobia differ from controls in their processing of emotional faces. For instance, people with social phobia show increased attention to briefly presented threatening faces. However, when exposure times are increased, the direction of this attentional bias is more unclear. Studies investigating eye movements have found both increased as we...
