Background Previous functional MRI studies have revealed that ongoing clinical pain in different chronic pain syndromes is directly correlated to the connectivity strength of the resting default mode network (DMN) with the insula. Here, we investigated seed-based resting state DMN-insula connectivity during acute migraine headaches. Methods Thirteen migraine without aura patients (MI) underwent 3 T MRI scans during the initial six hours of a spontaneous migraine attack, and were compared to a group of 19 healthy volunteers (HV).

Previous studies empirically support the existence of a distinctive association between deontological (but not altruistic) guilt and both disgust and obsessive-compulsive (OC) symptoms. Given that the neural substrate underlying deontological guilt comprises brain regions strictly implicated in the emotion of disgust (i.e. the insula), the present study aimed to test the hypothesis that indirect stimulation of the insula via transcranial direct current stimulation (tDCS) would enhance disgust and morality in the deontological domain.

Awareness of psychophysiological changes has been proposed to play a role in duration perception; however, evidence on whether interoceptive awareness affects timing is mixed, and it is not clear which task features favor the reliance on bodily changes to track time. Here we tested the hypothesis that interoceptive awareness is selectively involved in timing when the context does not provide reliable cues on elapsed time.

Transcranial Direct Current Stimulation (tDCS) is a promising tool for the treatment of depression and the dorsolateral prefrontal cortex (dlPFC) is often targeted when exploring tDCS effects on mood. However, the basic effects of tDCS on momentary emotions are inconsistent. We tested whether a single-session of anodal tDCS over the left temporal lobe (T3), topographically closer to the insular cortex than dlPFC, had effects on both vagally-mediated heart rate variability (HRV) and momentary affect in healthy participants.
