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.
Prefrontal cortex involvement in preattentive auditory deviance detection: neuroimaging and electrophysiological evidence
Combining electrophysiological and hemodynamic measures of the auditory oddball.
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.
Segregating semantic and syntactic aspects of processing in the human brain: an fMRI investigation of different word types.
The findings that semantic and syntactic aspects of processing are both functionally distinct and involve different subparts of the neuronal network underlying word processing support a domain-specific organization of the language system are found.

This work identified regions that mediate either of the two mechanisms by combining functional magnetic resonance imaging with an experimental protocol controlling for refractoriness, and found that in the traditional oddball paradigm both mechanisms contribute to irregularity detection.

The fMRI activation pattern suggests that the superior temporal gyrus is involved in novelty detection, whereas accessing and retrieving semantic concepts related to novel sounds additionally engages the rPFC.
Interactions of the hippocampal system and the prefrontal cortex in learning language-like rules
Neural basis of processing sequential and hierarchical syntactic structures
The results suggest that the brain's involvement in syntactic processing is determined by the type of rule used, with BA 44/45 playing an important role during language processing when long‐distance dependencies are processed.
Brain Correlates of Language Learning: The Neuronal Dissociation of Rule-Based versus Similarity-Based Learning
It is shown by means of functional magnetic resonance imaging that the brain dissociates the two mechanisms: the left anterior hippocampus supports similarity-based learning, whereas the left ventral premotor cortex is selectively engaged by abstract rule processing.

It is inferred that visual processes of working memory can be trained specifically, and these effects can be functionally dissociated from alterations in general control processes common to both working memory trainings.
