Previous studies have shown insular activations involving sensory, motor, and affective processing. However, the functional roles of subdivisions within the human insula are still not well understood. In the present study, we used intracranial electroencephalography and electrical cortical stimulation to investigate the causal roles of subdivisions of the insula in auditory emotion perception in epilepsy patients implanted with depth electrodes in this brain region. The posterior and the…

Revealing the functions of supra-temporal and insular auditory responsive areas in humans

These findings suggest that even the InsP has similar basic auditory response properties to the primary or non-primary cortex, it may not directly participate in the formation of auditory perception.

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.

Role of the insula in top–down processing: an intracranial EEG study using a visual oddball detection paradigm

Results suggest that visual targets elicit a P300 in the aI which corresponds in latency to the P3b component, suggesting that this region is involved in top–down processing of task-relevant information.

Towards a neural model of infant cry perception

The present meta-analysis confirmed involvement of the auditory system, the thalamocingulate circuit, the dorsal anterior insula, the pre-supplementary motor area and dorsomedial prefrontal cortex and the inferior frontal gyrus in infant cry perception, but not of the reward pathway.

Cortical Responses to Vowel Sequences in Awake and Anesthetized States: A Human Intracranial Electrophysiology Study.

Intracranial electroencephalography is used to examine cortical responses to vowel sequences during induction of general anesthesia with propofol to identify putative biomarkers of LOC and serve as a foundation for future investigations of altered sensory processing.

Expanding Simulation Models of Emotional Understanding: The Case for Different Modalities, Body-State Simulation Prominence, and Developmental Trajectories

This review article argues that simulation accounts of emotion recognition would benefit from three key extensions, including fuller consideration be given to simulation of bodily and vocal expressions, given that the body and voice are also important expressive channels for providing cues to another’s emotional state.

Functional geometry of auditory cortical resting state networks derived from intracranial electrophysiology

DME applied to resting state intracranial electroencephalography obtained in neurosurgical patients exhibited a hierarchical organization, symmetric between the two hemispheres and robust to the choice of iEEG frequency band, connectivity metric, and imaging modality.

Positive hysteresis in emotion recognition: Face processing visual regions are involved in perceptual persistence, which mediates interactions between anterior insula and medial prefrontal cortex

The hypothesis that high-order regions are involved in perceptual stabilization and decision during perceptual persistence (positive hysteresis) is supported and evidence to the role of the anterior insula as a hub of sensory information in perceptual decision-making is added.

Supramodal Representations of Perceived Emotions in the Human Brain

It is suggested that MPFC and STS represent perceived emotions at an abstract, modality-independent level, and thus play a key role in the understanding and categorization of others' emotional mental states.

The role of anterior insular cortex in social emotions

A model is presented suggesting that AI is not only involved in representing current states, but also in predicting emotional states relevant to the self and others, and implies that AI plays a dominant role in decision making in complex and uncertain environments.

Anterior insular cortex activity to emotional salience of voices in a passive oddball paradigm

The results revealed that disgusted relative to happy syllables elicited stronger MMNm-related cortical activities in the right AIC and precentral gyrus along with the left posterior insular cortex, supramarginal cortex, transverse temporal cortex, and upper bank of superior temporal cortex.

Adaptation to Vocal Expressions Reveals Multistep Perception of Auditory Emotion

It is found that bilateral voice-sensitive auditory regions as well as right amygdala coded the physical difference between consecutive stimuli and activity in bilateral anterior insulae, medial superior frontal cortex, precuneus, and subcortical regions such as bilateral hippocampi depended predominantly on the perceptual difference between morphs.
