Attentional Modulation in the Detection of Irrelevant Deviance: A Simultaneous ERP/fMRI Study

TLDR
The fMRI contrast D > S in the difficult task revealed activation on the right superior temporal gyrus (STG) and extending ventrally into the superior temporal sulcus, suggesting this region's involvement in involuntary attention shifting toward unattended, infrequent sounds.

Neural events leading to and associated with detection of sounds under high processing load

TLDR
Results are consistent with a limited capacity and late selection view of attention and demonstrate that variability in auditory detection is related to modulation of activity in multimodal parietal and frontal networks active ∼ 200 ms after target onset.

Temporal expectation modulates cortical dynamics of sensory memory

TLDR
How patterns of alpha power orchestrate sensory memory decay are outlined, and a refined perspective on alpha power and its inhibitory role across brain space and time is encouraged, to reflect the allocation of neural resources as sensory memory representations fade.

Is the failure to detect stimulus deviance during sleep due to a rapid fading of sensory memory or a degradation of stimulus encoding?

TLDR
A rapid rate of presentation is used in an attempt to capture mismatch‐related negativity prior to the fading of sensory memory, and there was little evidence of the DRN or the MMN during sleep following the presentation of the small deviant.

Temporal Expectation Modulates the Cortical Dynamics of Short-Term Memory

TLDR
The present data show how patterns of alpha power orchestrate short-term memory decay and encourage a more nuanced perspective on alpha power across brain space and time beyond its inhibitory role.

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

TLDR
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.

Neural Mechanisms of Involuntary Attention to Acoustic Novelty and Change

TLDR
The present results suggest the involvement of two different neural mechanisms in triggering involuntary attention to acoustic novelty and change: a transient-detector mechanism activated by novel sounds and reflected in the N1 and a stimulus-change detector mechanism activated in the MMN.

Combining electrophysiological and hemodynamic measures of the auditory oddball.

TLDR
Inverse solutions for dipole orientation provide evidence for significant activation close to Heschl's gyri during deviancy processing in the 110-160-ms time interval (MMN), whereas target detection could be modeled by two dipoles in the superior temporal gyrus between 320 and 380 ms.

The neuronal response patterns that are required for an adequate behavioural reaction to subjectively relevant changes in the environment are commonly studied by means of oddball paradigms, in which

The role of attention in auditory information processing as revealed by event-related potentials and other brain measures of cognitive function

TLDR
The role of attention and automaticity in auditory processing as revealed by event-related potential (ERP) research is examined, suggesting that even unattended stimuli may be semantically processed, without assuming automatic semantic processing or late selection in selective attention.

Brain generators implicated in the processing of auditory stimulus deviance: a topographic event-related potential study.

TLDR
The results showed that, in all cases, the negative wave elicited by the deviant stimuli showed the highest amplitudes over the right hemiscalp irrespective of the ear of stimulation or the direction of attention, and this asymmetric potential distribution could be attributed to the sum of activities of two sets of neural generators.

Cerebral Generators of Mismatch Negativity (MMN) and Its Magnetic Counterpart (MMNm) Elicited by Sound Changes

TLDR
Results from studies aimed at localizing cerebral generators of MMN indicate that a major MMN source is located in the auditory cortex, and intracranial MMN recordings in animals suggest that at least in some species, MMN subcomponents also may be generated in the thalamus and hippocampus.

Brain indices of automatic pattern processing

TLDR
The results suggest that the processing of auditory patterns occurs automatically, and depends on a rapidly fading short-term acoustic memory.
