There were differences between the two groups in activations of the posterior cingulate cortex and the coupling between this region and the amygdala which is central to fear and anxiety.

«In this study, we focused on the activity of the anterior cingulate cortex, which has been shown by others to be related to error processing, and which we have shown to be associated with fatigue,» said Dr. Wylie, who is associate director of Neuroscience Research and the Rocco Ortenzio Neuroimaging Center at Kessler Foundation.

«We challenged participants with difficult tasks of working memory, and assessed which parts of the anterior cingulate cortex were associated with error processing,» he explained.

Comparing MRI brain images of eight Dobermans with CCD to the control group, Ogata found that the CCD group had higher total brain and gray matter volumes, lower gray matter densities in the dorsal anterior cingulate cortex and right anterior insula, and higher fractional anisotropy in the splenium of the corpus callosum (the degree of which correlated with the severity of the behavioral traits).

Notable, areas in the medial orbitofrontal region and the anterior cingulate cortex, which are relevant for self - referential appraisal and aesthetic judgments, were found to be activated during the listening.

When humans are torn between paying attention to two different things, it triggers a «conflict» circuit in a brain region called the dorsal anterior cingulate cortex (dACC) which is part of a larger brain structure controlling rational thought and emotions.

Monkeys typically find other monkeys impossible to ignore, and this experiment was no exception: the monkeys often failed at the reward task because they looked at the faces, especially if the faces depicted emotion.When humans are torn between paying attention to two different things, it triggers a «conflict» circuit in a brain region called the dorsal anterior cingulate cortex (dACC) which is part of a larger brain structure controlling rational thought and emotions.Using a tiny sensor implanted in the dACCs of the monkeys, Platt's group was able to measure the electrical activity of single neurons.

The default - mode network (DMN) is a prominent network which includes the posterior cingulate cortex (PCC), medial prefrontal cortex (mPFC), medial temporal lobes (MTL), and angular gyrus (AG).

«In this study, we focused on the activity of the anterior cingulate cortex, which has been shown by others to be related to error processing, and which we have shown to be associated with fatigue,

However, not much is known with regards to how or if poor sleep is affecting a particular brain area called the dorsal anterior cingulate cortex (DACC), which is involved in the regulation of negative emotional responses.

MRI scans have shown that meditation activates the calming anterior cingulate cortex, which is pretty cool.

[11] Researchers have also discovered that it takes more effort for a brain area known as the dorsal anterior cingulate cortex to modify emotional responses which are negative in individuals with depression who have poor sleep patterns.

Louann Brizendine, MD, a neuropsychologist at the University of California, San Francisco and author of The Female Brain, says there is a part of our brain called the anterior cingulate cortex, which she dubs the «worrywart center.»

It was also revealed that brain activity increased in the orbito - frontal cortex, anterior insula and anterior cingulate cortex areas, which all play a part in how the brain shapes a pain experience from nerve signals coming from the body.

ABSTRACT: Anterior cingulated cortex (ACC) is involved in «the state in which patients do not care much about pain despite its presence» which is a goal of psychosomatic treatment.

Research also implicates a distributed network within the prefrontal cortex through which attention is deployed to closely monitor performance, incorporating feedback, as individuals then call on more specialized cognitive control mechanisms to modify subsequent behaviour.30 - 32 Anxiety related perturbations in this pattern are evident in both children33 and adults.34 Imaging studies have implicated the anterior cingulate cortex (ACC) in this process, as it appears to be hyperactive in anxious individuals during tasks requiring cognitive or «top down» control.35

Anterior cingulated cortex (ACC) is involved in «the state in which patients do not care much about pain despite its presence» which is a goal of psychosomatic treatment.

Activity of the subgenual cingulate cortex, which takes part in the regulation of the limbic activity, seems to play an important role in the response to CBT like in the response to antidepressant treatment.

At a second point in time, their brains were scanned while they participated in a virtual social task in the scanner, during which they were gradually excluded from the social interaction; this paradigm has previously been found to provoke significant social distress that is correlated with activity in the dorsal anterior cingulate cortex (dACC)(31), a brain region associated with monitoring threat.

Given their typical age of onset, a broad range of mental disorders are increasingly being understood as the result of aberrations of developmental processes that normally occur in the adolescent brain.4 — 6 Executive functioning, and its neurobiological substrate, the prefrontal cortex, matures during adolescence.5 The relatively late maturation of executive functioning is adaptive in most cases, underpinning characteristic adolescent behaviours such as social interaction, risk taking and sensation seeking which promote successful adult development and independence.6 However, in some cases it appears that the delayed maturation of prefrontal regulatory regions leads to the development of mental illness, with neurobiological studies indicating a broad deficit in executive functioning which precedes and underpins a range of psychopathology.7 A recent meta - analysis of neuroimaging studies focusing on a range of psychotic and non-psychotic mental illnesses found that grey matter loss in the dorsal anterior cingulate, and left and right insula, was common across diagnoses.8 In a healthy sample, this study also demonstrated that lower grey matter in these regions was found to be associated with deficits in executive functioning performance.

In this model, the cognitive control system including prefrontal and parietal regions and the anterior cingulate is crucial to decision - making but is functionally dominated by a second affective system that includes regions which are important to processing reward and social and emotional salience, including but not limited to the amygdala, ventral striatum, orbitofrontal cortex, medial prefrontal cortex, and the superior temporal sulcus.
