Functional organization of the human anterior insular cortex

Auditory, somatosensory, and multisensory insular cortex in the rat.

It is proposed that integration of auditory and somatotopically organized somatosensory modalities reported here may play a role in auditory fear conditioning.

The role of the insula in speech and language processing

[Insula, a "mysterious" island in our brain -- minireview].

In conclusion, insula may serve as primary (unimodal) cortical area for olfactory, taste and viscerosensory information, and acts as a multimodal cortical association area in the emotional, cognitive, limbic and autonomic systems in the brain.

Contribution of the anterior insula to temporal auditory processing deficits in developmental dyslexia

It is suggested that the anterior insula represents an important neural correlate of deficient temporal processing of speech and nonspeech sounds in dyslexia and that these operations of intrasylvian cortex also extend to the linguistic domain.

Auditory deviance detection in the human insula: An intracranial EEG study

High frequency EEG activity from 90 intracranial insular electrodes across 16 patients who were candidates for resective epilepsy surgery while they passively listened to a stream of standard and deviant tones indicates that the human insula is engaged during auditory deviance detection.

Contributions of the Insula to Cognition and Emotion

Functional neuroimaging studies have found insula hyper-activations, typically in conjunction with anterior cingulate cortex, for all manner of experimental tasks including those involving perception, intentional action, and consciousness.

The insular cortex: a review.




The functional anatomy of recovery from auditory agnosia. A PET study of sound categorization in a neurological patient and normal controls.

Bilateral activation (with recruitment of areas homologous to those known to be responsible for normal function), the engagement of peri-infarct regions, and the involvement of a more widespread neocortical network are mechanisms of functional reorganization after injury that may enable recovery from, or compensation for, cognitive deficits.

Spatial and temporal auditory processing deficits following right hemisphere infarction. A psychophysical study.

This case provides further evidence for the existence of amusia as a distinct form of auditory agnosia, but does not support the hypothesis that bilateral lesions are required to produce such a deficit.

A functional study of auditory verbal imagery

These results are consistent with the use of the ‘articulatory loop' during both inner speech and auditory verbal imagery, and the greater engagement of verbal self-monitoring during auditoryverbal imagery.

The insular lobe in primates including humans.

The broad concept of the insula has been outlined and it is demonstrated that the insular lobe has connections with portions of the frontal, parietal, and temporal lobes as well as of the cingulate gyrus.

Insular cortex and neighboring fields in the cat: A redefinition based on cortical microarchitecture and connections with the thalamus

Cortical areas, which resemble the insular fields of other mammals, are reported that are located in the cat's orbital gyrus and anterior rhinal sulcus, and interact with a wide array of sensory, motor, and limbic thalamic nuclei.

A comparison of visual and auditory motion processing in human cerebral cortex.

Together, these results identify human cortical regions involved in polysensory integration and the attentional selection of cross-modal motion information.

Detection of Audio-Visual Integration Sites in Humans by Application of Electrophysiological Criteria to the BOLD Effect

The efficacy of using an analytic approach informed by electrophysiology to identify multisensory integration sites in humans is demonstrated and the particular network of brain areas implicated in these crossmodal integrative processes are suggested to be dependent on the nature of the correspondence between the different sensory inputs.

Cortical connections of the insular and adjacent parieto-temporal fields in the cat.

The main finding is that despite their relatively small size and close apposition, the connections of the insular and adjacent areas are far more widespread and more specific to each area than previously realized, suggesting that each area is involved in disparate aspects of cortical integration.
