چکیده
Figure 1. Structural and overlapping functional correlates of social influence. Statistical maps are overlaid onto a standard MNI brain at coordinates: –40 mm, 33 mm, –4 mm. (A) OFC regions in which GM correlated with social influence on value (Binf) (threshold p < 0.001, FWE corrected at p < 0.05; right peak 36 mm 33 mm –10 mm, PFWE = 0.023, T = 5.56, 73 voxels; left peak –33 mm 28 mm –16 mm, PFWE = 0.029, T = 5.43, 183 voxels. (B) Mean GM value (a.u.) within the entire right cluster (red triangles) and entire left cluster (blue circles) plotted against social influence on value (Binf). GM values were mean corrected. (C) Overlap (green) in middle frontal gyrus functional activity predicted by conjunction of lOFCGM and Binf during disagreement with experts (vs. agreement) about object value (peak: –40 mm 46 mm 4 mm, Z = 3.72, 768 voxels).

Reduced resting-state functional connectivity between amygdala and orbitofrontal cortex in social anxiety disorder
Social anxiety disorder patients suffer from excessive anxious responses in social interaction leading to avoidance behavior and social impairment. Although the amygdala has a central role in perception and processing of threatening cues, little is known about the involved networks and corresponding dysfunctions in social anxiety. Therefore, this study aims to investigate the functional connect...
متن کاملBrief Communications Orbitofrontal Cortex Lesions Alter Anxiety-Related Activity in the Primate Bed Nucleus of Stria Terminalis
In children, behavioral inhibition (BI) in response to potential threat predicts the development of anxiety and affective disorders, and primate lesion studies suggest involvement of the orbitofrontal cortex (OFC) in mediating BI. Lesion studies are essential for establishing causality in brain– behavior relationships, but should be interpreted cautiously because the impact of a discrete lesion...

متن کاملOrbitofrontal cortex and anterior cingulate cortex are modulated by motivated social cognition.
Neural research on social cognition has not examined motivations known to influence social cognition. One fundamental motivation in social cognition is positivity motivation, that is, the desire to view close others in an overly positive light. Positivity motivation does not extend to non-close others. The current functional magnetic resonance imaging study is the first to identify neural regio...
متن کاملRegional cortical thinning of the orbitofrontal cortex in medication-naïve female patients with major depressive disorder is not associated with MAOA-uVNTR polymorphism
BACKGROUND Orbitofrontal cortex alterations have been suggested to underlie the impaired mood regulation in depression. MAOA-uVNTR (monoamine oxidase A-upstream variable number of tandem repeats) polymorphism has been reported to be associated with major depressive disorder by various studies. The influence of MAOA-uVNTR genotype on function and structure of the orbitofrontal cortex has previou...
