Sensitive Periods for the Effects of Childhood Maltreatment on Functional Connectivity in Cognitive Control and Risk Processing Systems
… task- based 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 …

Age and Family History of Alzheimer's Disease and Related Dementias as Predictors of Locus Coeruleus and Salience Network Connectivity
… 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, family history of Alzheimer's Disease, and …

Seeking the neural basis of grammar : English noun and verb morphological processing investigated with rapid event-related fMRI and intracortical electrophysiology
… 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 accessing nouns …

EXAMINING THE NEUROBIOLOGY OF NON-SUICIDAL SELF-INJURY IN CHILDREN AND ADOLESCENTS: THE ROLE OF REWARD RESPONSIVITY
… prefrontal cortex [vlPFC; vmPFC], and insula) and whole-brain connectivity (utilizing bilateral DS, mPFC, and insula seed ROIs) in youth with and without NSSI. We used two reward tasks, in order to examine differences between groups across domains of reward (i.e., monetary and social). …

Defensive Neurophysiological Response: Exploring the Neural and Autonoic Correlates of Social Behavior
Current literature suggests neurological (i.e., insula, amygdala) and autonomic (i.e., respiratory sinus arrhythmia; RSA) markers of language, social, and behavioral challenges in autism spectrum disorders (ASD; Bal et al., 2010; DiMartino, Ross, et al., 2009; Lorenzi, Patriquin, & Scarpa, 2011; …

Functional Connectivity of Reward Networks: Characterizing Mechanistic Underpinnings Involved in Positive Affect Deficits within Social Anxiety Disorder
… of interest (ROIs)-couplings (i.e., OFC and insula, OFC and subgenual cingulate, insula and cingulate, and cingulate and subgenual cingulate) and diminished PA were present in individuals with SAD, but not controls. Lastly, results demonstrated that individuals with SAD had higher variability …

Substrates of social functioning in individuals with VCFS
… VCFS patients would exhibit larger amygdala and insula volumes and smaller prefrontal cortex (PFC), orbitofrontal cortex (OFC), dorsolateral prefrontal cortex (DLPFC), insula, superior temorpal sulcus (STS), and anterior cingulate cortex (ACC) volumes relative to controls. In addition, scores on …

Kardiosensibilität, Emotionen und kortikales Geschehen
… um viszerale Regulationsstrukturen wie die Insula, das anteriore Cingulum, den präfrontalen Kortex und die somatosensorischen Kortizes handeln könnte. Des weiteren wurde postuliert, dass Unterschiede in der Kardiosensibilität sich sowohl in der Amplitude des HEP als auch in den …

Exploring the relationships among impulsivity, interpersonal difficulties, and social risk-taking in borderline personality disorder: behavioural influences and neural correlates
… 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 …

Childhood Trauma And Emotion Processing Neurocircuitry
… processing regions, including the amygdala, insula, and pregenual/subgenual anterior cingulate cortex (pgACC/sgACC). To examine the relevance of observed neurological changes, we evaluate behavioral performance on emotion processing neuropsychological tasks, as well as specific dimensions of …

From the body to the brain: Studying drug delivery and physiological interactions using MRI
… designed a study to investigate the role of the insula, a cortical mediator of peripheral physiological signals, in responses to opioid exposure. With molecular imaging approaches, we show the insula shapes drug-dependent brain phenotypes and physiological responses during substance exposure and …

Sensorimotor Recovery, Functional and Structural Brain Plasticity, and the Development of Chronic Pain Following Upper Limb Peripheral Nerve Transection and Microsurgical Repair
… abnormalities were also identified in the right insula. PNI-P patients had thinning within the right middle insula and a corresponding decrease in white matter pathways projecting into/out of that region. PNI-P patients also had white matter abnormalities in pathways feeding into/out of the …

The Neural Correlates of Guilt and Restitution During a Social Decision Making Task
… showed increased BOLD signal in the amygdala, insula, and the superior temporal sulcus. The present results are consistent with past studies that indicate an important role of the vlPFC and mPFC for processing aversive social cues and to resolve decision conflict.

BRAIN STRUCTURE AND FUNCTION ASSOCIATED WITH EMOTION DYSREGULATION IN TYPICAL DEVELOPMENT AND NEURODEVELOPMENTAL DISORDERS
… the association of ED with both GMV and FC in insula and inferior parietal gyrus among TD. In study 2, FC and GMV in ventral medial prefrontal cortex were associated with ED among clinical populations. These findings highlighted the gender differences in the neurobiology of ED and the …

The influence of proficiency and age of acquisition on second language processing: An fMRI study of Mandarin-English bilinguals
… is accounted for, while activity in right insula, right middle temporal gyrus, and left parahippocampal gyrus was modulated by L2 proficiency regardless of AoA. These results suggest that brain organization of L2 lexico-semantic processing is susceptible to L2 ability levels as well as …

The impact of stress on the prefrontal cortex: a view of how socioeconomic status impacts executive function
… middle frontal cortex, inferior frontal cortex, insula, and anterior cingulate cortex. Within the bigger SES framework, SES was related to cortisol reactivity and executive function. SES differences were found in total grey matter and regional cortical thickness within the PFC including the …

The Dissociation of Valence and Intensity Using Alliesthesia and Thermal Stimulation
… intensity was correlated with activity in the insula, thalamus and striatum, among others. Our results suggest segregated patterns of neural activity underlying perceptions of valence and intensity, consistent with dimensional models of emotion.

From Neural Dynamics to Psychological Profiles: A Comprehensive Study of Anxiety in Young and Adult Individuals
… anxious individuals, linked to areas such as the insula and the anterior cingulate, and white matter networks with greater concentration in lower anxious individuals, linked to the insula and the precuneus. Additionally, elevated stress and impulsivity were found in the higher anxiety group. Study …
