Neuroeconomics of Reward Information and Motivation
… in two brain regions: nucleus accumbens and anterior insula. Further, the nucleus accumbens activation mediates the predictive effects of anterior insula. These results show that idiosyncrasies in reward efficacy persist in the absence of a choice environment.</p><p>Chapters 6 and 7 conclude …

Exploration of the influence of emotionally primed environments on creativity and related patterns of brain activity
… of the dorsolateral prefrontal cortex (DLPFC), anterior cingulate gyrus (ACC), and anterior insula are active under both stimuli associated with increased divergent thinking. Future work is needed to investigate specifically how these brain regions may affect creativity and design cognition and …

Seeking the neural basis of grammar : English noun and verb morphological processing investigated with rapid event-related fMRI and intracortical electrophysiology
… 2.) Other areas are involved, including BA47, anterior insula, and SMA, 3.) Broca's area and BA47 respond to application of abstract grammatical features, even without phonological manipulations, 4.) Morphophonological manipulation additionally recruits insula and SMA, 5.) While simply …

Resting-State Functional Connectivity in Veterans with Post-Traumatic Stress Disorder and Combat-Exposed Control Veterans: A Graph Theory Based Network Analysis
… network and lower connectivity between anterior and posterior default-mode regions compared to both Control Veterans and Connectome Controls. PTSD networks more consistently included the right amygdala in the representative anterior insula module compared to each control group, …

Translational Neuroimaging of Emotion Processes in Posttraumatic Stress Disorder and Depression
… MDD studies, two regions of the brain, the right anterior insula and the subgenual anterior cingulate cortex, exhibited pretreatment responses to negative emotional stimuli that were predictive of clinical response to treatment. Considered together, this work demonstrates the translational utility …

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 …

RESTING-STATE FUNCTIONAL CONNECTIVITY CORRELATES OF ATTENTIONAL BIAS IN AN EMOTIONAL FREE VIEWING PARADIGM: AN EYE-TRACKING INVESTIGATION
… prefrontal cortex, lateral prefrontal cortex, anterior insula, amygdala, and superior frontal gyrus. Attentional biases to negative/threat were not associated with stress, anxious, or depressive symptomatology measured by self-report. Lastly, eye-movement measures were found to be largely …

An Investigation Into The Neural Nature Of Persecutory Ideation
… during neuroimaging. We demonstrated a dorsal anterior cingulate and anterior insula (dACC-AI) network, a left frontal-parietal (lF-P) network, and a ventral medial orbital prefrontal (vmPFC/OFC) network were associated with distinct forms of distrust. We then revealed only the connectivity …

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 games, …

Exploring the relationships among impulsivity, interpersonal difficulties, and social risk-taking in borderline personality disorder: behavioural influences and neural correlates
… 3 finds that individuals with BPD show decreased anterior insula response to the difference in risk between the gamble they select and the unchosen gamble, though it did not find a relationship between insula response and BPD symptoms. Together, these studies show that individuals with BPD respond …

Neuroimaging Depression Risk in a Sample of Never-Depressed Children
… activity in salience processing regions (i.e., anterior insula) and reward processing (i.e., putamen) during critical maternal feedback (Study 2), and resting-state functional connectivity within the Central Executive Network and Salience Network (Study 3). I also demonstrated that children with …

The influence of the trait-like tendency to rely on declarative- or procedural- like memory systems on the development of habits and compulsive behaviours in the rat
… a selective reduction in neural activity in the anterior insula and its afferent network in place learners. These results, taken together, challenge conventional thought regarding the relationship between declarative and procedural memory systems and the development of habits and compulsive …

Investigating reinforcement learning processes in depression and substance use disorder: translational, computational and neuroimaging approaches.
… functional connectivity from the amygdala to the anterior cingulate cortex, infralimbic cortex and insular cortex compared to males. The subsequent chapter uses a computational approach to investigate latent vulnerability variables in cocaine addiction. A longitudinal dataset acquired in rats was …

Predictive Processing Alterations in Psychosis Across Illness Stage, Hierarchical Level and Thematic Domain
… of a more circumspect disruption to (right) anterior insula, whose negative relationship with learning rate was replicated (Chapter 5). Interestingly, the behavioural case-control study of this task in Chapter 7 found reduced confidence-modulation of choice temperature in CSZ – in the absence …
