Disgust and the insula: fMRI responses to pictures of mutilation and contamination

  title={Disgust and the insula: fMRI responses to pictures of mutilation and contamination},
  author={Paul Wright and G. He and Nathan Andrew Shapira and Wayne K. Goodman and Y. Liu},
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… 

Disgust sensitivity predicts the insula and pallidal response to pictures of disgusting foods

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.

Hemodynamic brain correlates of disgust and fear ratings

The neural representation of typical and atypical experiences of negative images: comparing fear, disgust and morbid fascination.

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.

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 with

Lateralized Deficits of Disgust Processing After Insula-Basal Ganglia Damage

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.

Insular atrophy and diminished disgust reactivity.

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.

The Insular Cortex: Relationship to Skin Conductance Responses to Facial Expression of Emotion in Temporal Lobe Epilepsy

Thickness of insular cortices and bilateral skin conductance responses in healthy subjects in addition to a small number of patients with temporal lobe epilepsy is examined to find relationships between the thickness of the insula and SCR to each task.



The insula is not specifically involved in disgust processing: an fMRI study

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.

Brain activation by disgust-inducing pictures in obsessive-compulsive disorder

A specific neural substrate for perceiving facial expressions of disgust

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.

Neural structures associated with recognition of facial expressions of basic emotions

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.

Impaired recognition and experience of disgust following brain injury

Evidence is described, from a patient with insula and putamen damage, for a neural system for recognizing social signals of disgust from multiple modalities.

Dissociable neural systems for recognizing emotions

Functional Neuroanatomy of Emotion: A Meta-Analysis of Emotion Activation Studies in PET and fMRI

A critical comparison of findings across individual studies is provided and suggests that separate brain regions are involved in different aspects of emotion.

A differential neural response in obsessive–compulsive disorder patients with washing compared with checking symptoms to disgust

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.
