This study investigated human anterior cingulate cortex (ACC) involvement during a task that dissociated expectancy violation from social rejection. Across two studies, participants underwent functional magnetic resonance imaging while making social judgments and receiving fictitious feedback that was either positive or negative and consistent or inconsistent with their expectations. The results demonstrate that the dorsal ACC is sensitive to expectancy violations, whereas the ventral ACC is… 
Rejection Sensitivity Polarizes Striatal–Medial Prefrontal Activity When Anticipating Social Feedback
TLDR
This study characterizes behavioral and neural responses when individuals anticipate social feedback and provides initial insight into the neural mechanisms involved in anticipating social evaluations as well as the cognitive processes that underlie rejection sensitivity.
The Negative Consequences of Threat
TLDR
This study used functional magnetic resonance imaging to identify the neural structures associated with women's underperformance on math tasks and revealed heightened activation in a neural region associated with social and emotional processing.
Is dorsal anterior cingulate cortex activation in response to social exclusion due to expectancy violation? An fMRI study
TLDR
It is suggested that the rVLPFC is critical for regulating social pain, whereas the dACC plays an important role in the detection of exclusion, as the neurobiological basis of social exclusion is different from that of mere expectancy violation.
Neural substrates of expectancy violation associated with social feedback in individuals with subthreshold depression.
TLDR
The observed alternations are specific to unexpected social feedback processing and highlight an important role of expectancy violation in the brain dysfunction of social feedback perception and evaluation in individuals at risk for depression.
The salience of self, not social pain, is encoded by dorsal anterior cingulate and insula
TLDR
This study shows that right AI and dACC are involved in processing the salience of being judged by others, irrespective of the quality of this judgment, which supports the idea that these regions are not specific to social rejection or even to pain or metaphorically painful experiences, but activate to self-relevant, highly salient information.
Neural Dynamics of Rejection Sensitivity
TLDR
Results suggest that responses in regions traditionally implicated in emotional processing and cognitive control are sensitive to rejection stimuli irrespective of RS, but that low RS individuals may activate prefrontal structures to regulate distress associated with viewing such images.
Dorsal Anterior Cingulate Cortex Responses to Repeated Social Evaluative Feedback in Young Women with and without a History of Depression
TLDR
Examining how the d ACC responds to repeated bouts of negative evaluation reveals a new dimension to the role of the dACC in processing exclusion and contributing to mental health outcomes in a population vulnerable to MDD.
Self-esteem modulates medial prefrontal cortical responses to evaluative social feedback.
TLDR
A functional role for the vACC/mPFC is proposed in representing the salience of social feedback and shaping perceptions of relative social standing.
Implicitly Priming the Social Brain: Failure to Find Neural Effects
TLDR
This study investigated the automaticity of social threat detection by examining how implicit primes affect neural responses to social stimuli, and failed to find any evidence that implicit priming induced changes at the neural level.

Does Rejection Hurt? An fMRI Study of Social Exclusion
TLDR
A neuroimaging study examined the neural correlates of social exclusion and tested the hypothesis that the brain bases of social pain are similar to those of physical pain, suggesting that RVPFC regulates the distress of socialclusion by disrupting ACC activity.
Anterior cingulate cortex, error detection, and the online monitoring of performance.
TLDR
Results confirm that this region shows activity during erroneous responses, but activity was also observed in the same region during correct responses under conditions of increased response competition, which suggests that the ACC detects conditions under which errors are likely to occur rather than errors themselves.

TLDR
Simulations show that high-pass filtering is desirable if the appropriate model for the hemodynamic response is used, and the power spectrum of the measured BOLD signal in rapid event-related paradigms is similar to that of the noise.
