Differential contributions of subregions of the dorsal anterior cingulate cortex to negative emotion in the common marmoset
The dorsal anterior cingulate cortex (dACC) has been implicated in a broad range of cognitive and emotional functions, including the processing of negative emotion. Furthermore, abnormalities in dACC activity have been associated with anxiety and depression, disorders in which negative emotion is …

Resting-State Functional Brain Networks in Bipolar Spectrum Disorder: A Graph Theoretical Investigation
… control region (dorsolateral prefrontal cortex), but increased connectivity of a brain region involved in the detection and processing of reward (bilateral orbitofrontal cortex), among participants at high risk for BSD. Participants with BSD showed increased inter-module connectivity of …

Time Course of Regional Brain Activity Associated With Top-Down Attentional Control in Depression
A network consisting of dorsal anterior cingulate cortex (dACC) and left dorsal lateral prefrontal cortex (LDLPFC) has been implicated in cognitive control. Very few studies have investigated how this network is altered in psychopathology, despite evidence that depression and anxiety are associated …

Salience and Frontoparietal Network Patterns in Children with Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder
… (FPN). The SN is a network anchored by bilateral anterior insula and the dorsal anterior cingulate cortex and has been implicated in “bottom-up” attentional processes for both internal and external events. The FPN is anchored by lateral prefrontal cortex areas and the parietal lobe and plays a …

Age and Family History of Alzheimer's Disease and Related Dementias as Predictors of Locus Coeruleus and Salience Network Connectivity
… with the salience network (SN), specifically the dorsal anterior cingulate cortex (dACC) and the insula, to coordinate and direct attention. The LC is a site of early Alzheimer's pathology and also experiences normal age-related declines in functioning. In this study, the associations between age, …

Psychological and neural mechanisms of stay/leave decision making
… a social rather than nonsocial context; and the dorsal anterior cingulate cortex showed differential activation as a function of stay and leave decisions and this pattern was reversed in the nonsocial and social context. Interpretation of these results are discussed in light of a fundamental need …

Psychological and Neural Processing of Social Risk and Discrepancy in Major Depressive Disorder
… in MDD, linked to activation in the dorsal anterior cingulate cortex and anterior insula, and suggesting a role for perfectionism as a transdiagnostic sensitivity to such discrepancies. Suggestions for future research are discussed, including increased utilisation of neuroeconomic …

Neural Mechanisms Promoting Biased Social Memories in Intergenerational Childhood Abuse
… a negativity bias in social memory, (2) whether anterior hippocampal activation during feedback encoding explains this relationship, and (3) whether a negativity bias in memory and anterior hippocampus activation mediate the relationship between childhood abuse and harsh parenting. Contrary to …

Sensitive Periods for the Effects of Childhood Maltreatment on Functional Connectivity in Cognitive Control and Risk Processing Systems
… functional connectivity in the insula and dACC (dorsal anterior cingulate cortex) during both risk processing and cognitive control, respectively. Although no sensitive periods emerged for the effects of abuse or neglect on functional connectivity during risk processing, chronic abuse (abuse …

Cognitive flexibility and fronto-parietal control dynamics in aging
… functions,” known to heavily involve the frontal cortex. The relationship between frontal brain activity and behavioral performance however, is not straightforward. Some studies find that increased activation in this region relates to better performance, while others, particularly studies that …

HD-tDCS over Frontal Cortex and Neuropsychological Functioning in Cognitively Impaired Older Adults
… neuronal activity in the brain. The frontal cortex serves as a brain circuitry hub connected to a variety of cortical and subcortical structures. Within the frontal cortex lies the dorsal anterior cingulate cortex (dACC) and pre-supplementary motor area (preSMA), which are differentially …
