Questioning the role of amygdala and insula in an attentional capture by emotional stimuli task
Sign Up to like & getrecommendations! Published in 2020 at "Human Brain Mapping"
DOI: 10.1002/hbm.25290
Abstract: Our senses are constantly monitoring the environment for emotionally salient stimuli that are potentially relevant for survival. Because of our limited cognitive resources, emotionally salient distractors prolong reaction times (RTs) as compared to neutral distractors.… read more here.

DOI: 10.1007/s00213-017-4550-8
Abstract: RationaleTobacco has a higher rate of dependence than other drugs of abuse. However, the psychopharmacological effects of nicotine are incongruent with the tenacity of tobacco addiction since nicotine does not produce robust euphoria in humans… read more here.

DOI: 10.1016/j.abrep.2018.01.002
Abstract: Relapse to smoking after initial abstinence is a major clinical challenge with significant public health consequences. At the brain and behavioral level, those who relapse to tobacco smoking have both greater cue-reactivity and lower inhibitory… read more here.

DOI: 10.1016/j.bbi.2019.03.008
Abstract: BACKGROUND Sickness behavioral changes elicited by inflammation may become prolonged and dysfunctional in patients with chronic disease, such as chronic hepatitis C (CHC). Neuroimaging studies show that the basal ganglia and insula are sensitive to… read more here.

07-Connectivity of the anterior insula differentiates participants with first-episode schizophrenia spectrum disorders from controls: A machine-learning study
Sign Up to like & getrecommendations! Published in 2018 at "Clinical Neurophysiology"
DOI: 10.1016/j.clinph.2018.01.027
Abstract: Early diagnosis of schizophrenia might reduce the negative impact of the untreated disease. Progressive functional/structural changes were repeatedly detected using classical between-group statistics. However, these findings have been due to their low sensitivity and specificity… read more here.

DOI: 10.1016/j.dcn.2017.12.006
Abstract: The insula is important for the processing of pleasant aspects of touch whereas its role in the processing of emotionally neutral touch has been less explored. Here, we used a network approach to investigate the… read more here.

Experience-dependent modulation of right anterior insula and sensorimotor regions as a function of noise-masked auditory feedback in singers and nonsingers
Sign Up to like & getrecommendations! Published in 2017 at "NeuroImage"
DOI: 10.1016/j.neuroimage.2016.11.059
Abstract: ABSTRACT Previous studies on vocal motor production in singing suggest that the right anterior insula (AI) plays a role in experience‐dependent modulation of feedback integration. Specifically, when somatosensory input was reduced via anesthesia of the… read more here.

DOI: 10.1017/s0033291722001398
Abstract: BACKGROUND Major depressive disorder (MDD) is often accompanied by changes in appetite and weight. Prior task-based functional magnetic resonance imaging (fMRI) findings suggest these MDD phenotypes are associated with altered reward and interoceptive processing. METHODS… read more here.

DOI: 10.1038/s41398-020-0833-7
Abstract: The anterior insular cortex plays a key role in the representation of interoceptive effects of drug and natural rewards and their integration with attention, executive function, and emotions, making it a potential target region for… read more here.

52. Abnormal Anterior Insula Activity During Fear Generalization in Schizophrenia
Sign Up to like & getrecommendations! Published in 2017 at "Schizophrenia Bulletin"
DOI: 10.1093/schbul/sbx021.071
Abstract: Abstract Background: Generalization from previous experiences allows us to evaluate the affective value of novel events. A breakdown of this fundamental ability may lead to incorrect attributions of affective value that could give rise to psychotic… read more here.

DOI: 10.1097/j.pain.0000000000001815
Abstract: Non-invasive measures of neuroinflammatory processes in humans could substantially aid diagnosis and therapeutic development for many disorders, including chronic pain. Several proton Magnetic Resonance Spectroscopy (H-MRS) metabolites have been linked with glial activity (i.e. choline… read more here.
