Abnormal superior temporal connectivity during fear perception in schizophrenia.
Patients with schizophrenia have difficulty in decoding facial affect. A study using event-related functional neuroimaging indicated that errors in fear detection in schizophrenia are associated with paradoxically higher activation in the amygdala and an associated network implicated in threat detection. Furthermore, this exaggerated activation to fearful faces correlated with severity of flat ...
متن کاملOverlapping activity in anterior insula during interoception and emotional experience
Classic theories of emotion posit that awareness of one's internal bodily states (interoception) is a key component of emotional experience. This view has been indirectly supported by data demonstrating similar patterns of brain activity - most importantly, in the anterior insula - during both interoception and emotion elicitation. However, no study has directly compared these two phenomena wit...
متن کاملMonetary reward suppresses anterior insula activity during social pain.
Social pain after exclusion by others activates brain regions also involved in physical pain. Here we evaluated whether monetary reward could compensate for the negative feeling of social pain in the brain. To address this question we used the unique technique of intracranial electroencephalography in subjects with drug resistant epilepsy. Specifically, we recorded theta activity from intracran...
متن کاملActivation of Anterior Insula during Self-Reflection
BACKGROUND Functional neuroimaging studies have suggested activation of midline frontoparietal brain regions to be at the core of self-related processes. However, although some studies reported involvement of the insula, little attention has been paid to this region as forming part of the "self"-network. METHODOLOGY/PRINCIPAL FINDINGS Using functional magnetic resonance imaging (fMRI), we aim...
متن کاملFunctional lateralization of the anterior insula during feedback processing.
Effective adaptive behavior rests on an appropriate understanding of how much responsibility we have over outcomes in the environment. This attribution of agency to ourselves or to an external event influences our behavioral and affective response to the outcomes. Despite its special importance to understanding human motivation and affect, the neural mechanisms involved in self-attributed rewar...
