Neural correlates of the automatic processing of threat facial signals.
The present study examined whether automaticity, defined here as independence from attentional modulation, is a fundamental principle of the neural systems specialized for processing social signals of environmental threat. Attention was focused on either scenes or faces presented in a single overlapping display. Facial expressions were neutral, fearful, or disgusted. Amygdala responses to facia...
متن کاملNeural correlates of affect processing and aggression in methamphetamine dependence.
CONTEXT Methamphetamine abuse is associated with high rates of aggression but few studies have addressed the contributing neurobiological factors. OBJECTIVE To quantify aggression, investigate function in the amygdala and prefrontal cortex, and assess relationships between brain function and behavior in methamphetamine-dependent individuals. DESIGN In a case-control study, aggression and br...
متن کاملNeural Correlates of warning Warning signals influence motor processing
5 Figures 28 Pages (including references and figure captions) Summary When observers initiate responses to visual targets, they do so sooner when a preceding stimulus indicates that the target will appear shortly. This consequence of a warning signal may change neural activity in one of four ways. On the sensory side, the warning signal may speed up the rate at which the target is registered by...
متن کاملAppetitive motivation predicts the neural response to facial signals of aggression.
The "behavioral approach system" (BAS) (Gray, 1990) has been primarily associated with reward processing and positive affect. However, additional research has demonstrated that the BAS plays a role in aggressive behavior, heightened experience of anger, and increased attention to facial signals of aggression. Using functional magnetic resonance imaging, we show that variation in the BAS trait i...
