Neuroimaging studies have found a correlation between activation in the anterior insula and love, and a correlation between activation in the posterior insula and lust. The present control-case study describes a neurological male patient, with a rare, circumscribed lesion in the anterior insula, whom we tested using a decision task that required he judge whether each of a series of attractive i...

BACKGROUND As both oral and verbal apraxia are related to vocal orofacial musculature, this study aimed at identifying brain regions impaired in cases with oral and verbal apraxia. METHODS In this non-experimental study, 46 left brain damaged subjects (17 females) aged 23-84 years, were examined by oral and verbal apraxia tasks. Impaired and spared Broca's area, insula, and middle frontal gyr...

fMRI studies have shown that the perception of facial disgust expressions specifically activates the insula. The present fMRI study investigated whether this structure is also involved in the processing of visual stimuli depicting non-mimic disgust elicitors compared to fear-inducing and neutral scenes. Twelve female subjects were scanned while viewing alternating blocks of 40 disgust-inducing,...

Tinnitus affects 15% of the population. Of these 1-2% are severely disabled by it. The role of the autonomic system in tinnitus is hardly being investigated. The aim of this study is to investigate the relationship between tinnitus distress and lateralization of the anterior insula, known to be involved in interoceptive awareness and (para)sympathetic changes. For this, Tinnitus Questionnaire s...

UNLABELLED Depression is associated with systemic inflammation, and the systemic inflammation caused by endotoxin administration elicits mild depressive symptoms such as fatigue and reduced interest. The neural correlates of depressive symptoms that result from systemic inflammation are poorly defined. The aim of this study was to use (18)F-FDG PET to identify brain regions involved in the resp...

The neural bases of anger are still a matter debate. In particular we do not know whether perception and experience rely on similar or different mechanisms. To study this topic, performed activation-likelihood-estimation meta-analyses human neuroimaging studies 61 previous experience. Anger analysis resulted in significant activation the amygdala, right superior temporal gyrus, fusiform gyrus I...

The insula, particularly its posterior portion, is often regarded as a primary cortex for pain. However, this interpretation is largely based on reverse inference, and a specific involvement of the insula in pain has never been demonstrated. Taking advantage of the high spatiotemporal resolution of direct intracerebral recordings, we investigated whether the human insula exhibits local field po...
