..An exemplar-based multidimensional model is proposed as an alternative account...

..g., that composites are more "attention-grabbing" than noncomposites). Finally, Experiment 4 demonstrates that the composite effects for identity and expression operate independently of one another...

..We conclude that the related emotions of disgust and anger associated with social disapproval are frequently impaired in HD and discuss factors that might cause one emotion to show more severe impairments than the other...

..Previous research has shown that facial identity is coded by an opponent-coding system; hence, these results also demonstrate that gaze is coded by a different representational system to facial identity...

..Our results also accord with comparative research showing an anterior to posterior gradient in the rat pallidum reflecting increased 'liking' of foods [Smith, K. S. and Berridge, K. C. (2005) J. Neurosci., 25, 849-8637]...

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

..Consistent with these findings, averted gaze in the adapted direction was misidentified as direct. Our study provides the first human evidence of dissociable neural systems for left and right gaze...

..Alongside this two-pathway framework, other possible models of facial identity and expression recognition, including one that has emerged from principal component analysis techniques, should be considered...

..We suggest that the dissociable effects found for fear and disgust are consistent with the differential effects of ageing on brain regions involved in these emotions...

..Additional subtraction contrasts largely confirmed these patterns. Our results demonstrate a considerable degree of overlap between the medial frontal areas involved in eye gaze processing and theory of mind tasks...

..Here we describe evidence, from a patient with insula and putamen damage, for a neural system for recognizing social signals of disgust from multiple modalities...

..The implications for models of face processing are discussed...

..We review this research and its implications for theories of emotion...

....

..The personality-mediated variation in the pathway from the ventral anterior cingulate cortex to the amygdala provides an account of why signals of aggression are interpreted as provocative by some individuals more than others...

....

..Our findings suggest a role for right anterior STS/STG in coding the direction of motion in dynamic social attention cues...

..Our findings highlight aversive processes in the insula as underlying the default bias and suggest that choosing the default may be rewarding in itself...

..Our results challenge previous interpretations regarding the underlying nature of neural representations made using fMRI RS paradigms...

..Our findings suggest the existence of a reciprocal influence between gaze direction and angry expressions...

....

..Our primary aim was to characterize explicit and implicit aspects of emotion function to determine whether deficits in these processes are present in girls with CD...

..Differences in the dynamic interactions within the human appetitive network in response to pictures of appetizing foods may determine an individual's risk of obesity...

..Our findings demonstrate the striking effects of personality in a non-clinical population, and show how this can distinguish the neural coding of anger and fear faces...

..The present data call for further consideration of the theoretical specifications of the mechanisms that lead to enhanced memory for emotional stimuli and their neural substrates...

..The results are discussed in relation to the tonic and phasic hypotheses of 5-HTTLPR-mediated modulation of amygdala activity...

....

..g., hyperphagic obesity)...

..These findings contribute to our developing understanding of how mood and memory interact...

..The results provide evidence that autism spectrum characteristics are reflected in neural structure and function across the typical (non-ASD) population...

..Our results support studies showing that similarity acts as a proximate neurobiological mechanism where prosocial behavior extends to unrelated strangers...

..It is plausible that the emotion recognition impairments observed contribute to the abnormal social behaviour that is characteristic of this condition...

..Our findings demonstrate that the amygdala response to emotional stimuli is not a function of arousal (or valence) alone and accord more with the proposal that the amygdala responds to the significance or relevance of an event...

..Our primary objective was to investigate whether female adolescents with CD show changes in grey matter volume. Our secondary aim was to assess for sex differences in the relationship between CD and brain structure...

..Here, we investigated whether the integrity of the white-matter pathways connecting these regions is abnormal and thus may represent a putative neurobiological marker for CD...

..The findings could potentially inform the developmental taxonomic theory of antisocial behaviour, which suggests that early-onset and adolescence-limited forms of CD are subject to different aetiological processes...

....

..This study provides the first evidence that communicative intent signaled via the auditory modality influences the perception of another individual's gaze...

..These findings suggest "size-invariant" RS to faces is a consequence of interactions between regions rather than being a localized effect...

....

....

..Our results provide evidence for multichannel coding of seen body orientation, with separate channels (or neuronal populations) selectively tuned to different body directions...

..Our findings provide evidence that humans have distinct populations of neurons that are selectively responsive to particular directions of seen gaze...

..We used functional magnetic resonance imaging (fMRI) to investigate the behavioural and neurocognitive correlates of happy and sad facial affect recognition in patients with mania...

..The acknowledgement of deficits in emotion recognition is important for management of both patients and their carers...

....

..These factors may also influence the brain's response to emotional stimuli. A synthesis of the relevant neuroimaging data must therefore take these factors into consideration...

..Our findings provide evidence of efficient coding of moral dimensions during narrative comprehension and demonstrate that this process does not require cognitively intense forms of principled reasoning...

..These results demonstrate that two different forms of environmental adversities interplay with 5-HTTLPR and thereby differentially impact amygdala and cortical reactivity...

..g., angry faces)...

..Our results suggest that the cortex in isolation from the entire pulvinar is incapable of recognizing fearful expressions...

..Thus, in anxiety-prone people attention is more likely to be held by an expression of anger, whereas attention is guided more potently by fearful facial expressions...

..The mood-manipulated group had increased sensitivity for anger expressions, and trait anxiety did not moderate these effects. Interpretations of the results related to the classification of fearful expressions are discussed...
