Although previous functional brain imaging studies have found that the insula responds selectively to facial expressions of disgust, it remains unclear whether the insula responds selectively to disgust-inducing pictures. In this fMRI study, healthy volunteers viewed pictures of contamination, human mutilation, attacks and neutral scenes during scanning, and then rated pictures for the ‘basic’ emotions. The anterior insula responded to contamination and mutilation but not attacks, while the… Expand
fMRI responses to pictures of mutilation and contamination
TLDR
The results of the fMRI experiment are in disagreement with the idea of selective disgust processing at the insula, and point to a network of brain regions involved in the decoding of stimulus salience and the regulation of attention. Expand
Disgust sensitivity predicts the insula and pallidal response to pictures of disgusting foods
TLDR
This study demonstrates that individual variation in disgust sensitivity is significantly correlated with participants' ventroanterior insular response to viewing pictures of disgusting, but not appetizing or bland, foods. Expand
Hemodynamic brain correlates of disgust and fear ratings
TLDR
This study correlated the participants' individual online reports of fear and disgust with their hemodynamic responses towards each of the fear- and disgust-inducing scenes, indicating that the processing of disgust- and fear-inducing pictures involves similar as well as distinct brain regions. Expand
The neural representation of typical and atypical experiences of negative images: comparing fear, disgust and morbid fascination.
TLDR
This study is the first to forward evidence about the neural representation of the experimentally unexplored state of morbid fascination and suggests that neural resources associated with the process of conceptualization contribute to the Neural representation of this state. Expand
Changes in EEG alpha power to different disgust elicitors: the specificity of mutilations
TLDR
In this EEG study, 34 participants viewed 4 film-clips depicting surgery, cockroach invasion, human attack and neutral landscape during EEG recording and then rated the clips for valence, arousal and the basic emotions. Expand
The temporal dynamics of insula activity to disgust and happy facial expressions: A magnetoencephalography study
TLDR
Findings support the notion that the insula is involved in the representation of interoceptive information during emotional processing, and reflect activation to emotionally arousing stimuli regardless of valence. Expand
Erroneously Disgusted: fMRI Study Supports Disgust-Related Neural Reuse in Obsessive-Compulsive Disorder (OCD)
Objective: fMRI scans of patients with obsessive-compulsive disorder (OCD) consistently show a hyperactivity of the insular cortex, a region responsible for disgust-processing, when confronted withExpand
Lateralized Deficits of Disgust Processing After Insula-Basal Ganglia Damage
TLDR
The present study provides the first behavioral evidence of hemispheric lateralization of a specific emotion in the human brain, and contributes to neurobiological models of disgust. Expand
Insular atrophy and diminished disgust reactivity.
TLDR
Results indicated that smaller insular volumes were associated with reduced disgust responding in self-report and physiological reactivity, but not in facial behavior, and underscore the central role of the insula in the experience and physiology of disgust. Expand
The Insular Cortex: Relationship to Skin Conductance Responses to Facial Expression of Emotion in Temporal Lobe Epilepsy
TLDR
Analysis of thickness of insular cortices and bilateral skin conductance responses in healthy subjects in addition to a small number of patients with temporal lobe epilepsy found relationships between the thickness of the insula and SCR to each task. Expand

The insula is not specifically involved in disgust processing: an fMRI study
TLDR
Findings do not fit the idea of the insula as a specific disgust processor, which is involved in the processing of visual stimuli depicting non-mimic disgust elicitors compared to fear-inducing and neutral scenes. Expand

TLDR
The neural effects of viewing disgusting and fear-inducing pictures in contrast to neutral pictures are explored and the existence of a common affective circuit is suggested. Expand
Brain activation by disgust-inducing pictures in obsessive-compulsive disorder
TLDR
This pilot study supports the relevance of disgust in the neurocircuitry of OCD with contamination-preoccupation symptoms; future studies looking at non-OCD individuals with high disgust ratings, non-contamination-preoccupied OCD individuals, and individuals with other anxiety disorders are needed. Expand
Both of Us Disgusted in My Insula The Common Neural Basis of Seeing and Feeling Disgust
TLDR
An fMRI study in which participants inhaled odorants producing a strong feeling of disgust and observed video clips showing the emotional facial expression of disgust found that observing an emotion activates the neural representation of that emotion. Expand
A specific neural substrate for perceiving facial expressions of disgust
TLDR
Functional magnetic resonance imaging was used to examine the neural substrate for perceiving disgust expressions and found the neural response to facial expressions of disgust in others is thus closely related to appraisal of distasteful stimuli. Expand
Neural structures associated with recognition of facial expressions of basic emotions
TLDR
The results support the hypotheses derived from neuropsychological findings, that recognition of disgust, fear and anger is based on separate neural systems, and that the output of these systems converges on frontal regions for further information processing. Expand
Impaired recognition and experience of disgust following brain injury
TLDR
Evidence is described, from a patient with insula and putamen damage, for a neural system for recognizing social signals of disgust from multiple modalities. Expand
Dissociable neural systems for recognizing emotions
TLDR
The hypothesis that the recognition of emotions would draw upon anatomically separable brain regions, depending on whether the stimuli were static or explicitly conveyed information regarding actions, is tested in a rare subject with extensive bilateral brain lesions, patient B. Expand
Functional Neuroanatomy of Emotion: A Meta-Analysis of Emotion Activation Studies in PET and fMRI
TLDR
A critical comparison of findings across individual studies is provided and suggests that separate brain regions are involved in different aspects of emotion. Expand
A differential neural response in obsessive–compulsive disorder patients with washing compared with checking symptoms to disgust
TLDR
Only washers demonstrate a neural response to washer-relevant disgust associated with emotion perception rather than attention to non-emotive visual detail, and this response is distinguished between washing and checking symptoms in OCD. Expand
