While the human insula is known to be involved in auditory processing, knowledge about its precise functional role and the underlying electrophysiology is limited. To assess its role in automatic auditory deviance detection we analyzed the high frequency EEG activity (75-145 Hz) 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. Deviant and standard tones differed… 

Electrophysiology of the Human Superior Temporal Sulcus during Speech Processing.

Functional distinctions between the upper (STSU) and the lower (STSL) bank, hemispheric asymmetries, and activity during self-initiated speech are clarified, suggesting feedback signaling within the auditory cortical hierarchy.

Auditory prediction hierarchy in the human hippocampus and amygdala

A distributed cortical-subcortical network underlying the generation of auditory predictions, comprising temporal cortex and the hippocampus and amygdala, is revealed, and it is suggested that the neural basis of sensory predictions and prediction error signals needs to be extended to sub cortical regions.

The brain tracks auditory rhythm predictability independent of selective attention

This is the first study to show that probability of rhythm violation influences rhythm predictability, independent of attention, and a right-lateralization of attention effects, but not predictions, suggested potentially different cortical processes.

The Effects of Working Memory Load on Auditory Distraction in Adults With Attention Deficit Hyperactivity Disorder

The results indicate that aADHD are more susceptible to noise interference when they are engaged in a primary task, and the ability to cope with auditory distraction appears to be related to the WM demands of the task and thus the capacity to deploy cognitive control.

Insights into human cognition from intracranial EEG: A review of audition, memory, internal cognition, and causality

How intracranial electroencephalography recordings are used to study human cognition with the spatiotemporal and single-trial precision traditionally limited to non-human animal research is discussed.

Decision and response monitoring during working memory are sequentially represented in the human insula

Emerging research supports a role of the insula in human cognition. Here, we used intracranial EEG to investigate the spatiotemporal dynamics in the insula during a verbal working memory (vWM) task.

Direct brain recordings reveal continuous encoding of structure in random stimuli

This work addresses the role of transitional probabilities as an implicit structure supporting the encoding of a random auditory stream and reveals the involvement of a network outside of the auditory system, including hippocampal, frontal, and temporal regions.

Quantifying Evoked Responses through Encoded Information

This work proposes a measure grounded in algorithmic information theory termed Encoded Information as a novel approach to analyze neurophysiological recordings and demonstrates that the information-based encoding can compete with conventional approaches such as the t-test or mutual information.

Neural Substrates and Models of Omission Responses and Predictive Processes

This approach may reveal the biological foundations of core concepts of predictive coding, and allow an empirical test of the framework’s promise to unify theoretical models of attention and perception.



Cortical Activation to Auditory Mismatch Elicited by Frequency Deviant and Complex Novel Sounds: A PET Study

Assessment of cortical blood flow to auditory stimulation in three conditions indicates a left hemisphere contribution to a frontotemporal network of auditory deviance processing and provides further evidence for a contribution of the frontal cortex to the processing of auditoryDeviance outside the focus of directed attention.

Intracerebral potentials to rare target and distractor auditory and visual stimuli. I. Superior temporal plane and parietal lobe.

High gamma activity in response to deviant auditory stimuli recorded directly from human cortex.

It is suggested that the high gamma oscillations are sensory-induced neocortical ripples, similar in physiological origin to the well-studied ripples of the hippocampus.

Differential Contribution of Frontal and Temporal Cortices to Auditory Change Detection: fMRI and ERP Results

The results suggest that the right fronto-opercular cortex is part of the neural network generating the MMN, and that small deviants were hardly detected under fMRI conditions.

Mismatch negativity to auditory stimulus change recorded directly from the human temporal cortex.

The intracranially recorded MMN was found to be attention independent and modality specific, and was confined to a rather small area in temporal cortex, which was different from the structures where attention-dependent N2 and P3 responses to the frequency change could be recorded.

Sensory Deviancy Detection Measured Directly Within the Human Nucleus Accumbens.

Direct human evidence is provided that the NAcc is a key component of a network engaged in encoding statistics of the sensory environmental and predicted generation of longer latency scalp potentials.

Neural signature of the conscious processing of auditory regularities

An auditory paradigm that evaluates cerebral responses to violations of temporal regularities that are either local in time or global across several seconds suggests that the presence of the global effect is a signature of conscious processing, although it can be absent in conscious subjects who are not aware of theglobal auditory regularities.
