Selective Interference with Syntactic Encoding during Sentence Production by Direct Electrocortical Stimulation of the Inferior Frontal Gyrus
It is suggested that the left inferior frontal gyrus plays an important role in the encoding of syntactic structure during sentence production, and cortical stimulation interference with syntactic encoding took several different forms.
Words are not enough: nonword repetition as an indicator of arcuate fasciculus integrity during brain tumor resection.
It is suggested that monitoring NWR intraoperatively may complement the standard naming tasks and could permit better preservation of the important language production functions subserved by the AF.
Variability of intraoperative electrostimulation parameters in conscious individuals: language cortex.
To optimize the identification of language areas during electrostimulation brain mapping, it is important to use different intensities of stimulation at the maximum possible currents, avoiding afterdischarges.
Application of electrical brain stimulation in the auditory language processing
Electrical brain stimulation techniques can reveal functional roles within brain regions and effective connections between brain regions during cognitive processing, and provide a new perspective for further exploring the neural mechanisms of auditory language processing.

In this review, the main achievements concerning networks involved in some aspects of language, visuo-spatial cognition, calculation and emotion will be highlighted.
From Mimicry to Language: A Neuroanatomically Based Evolutionary Model of the Emergence of Vocal Language
According to this model, the role of the ADS in vocal control enabled early Homo (Hominans) to name objects using monosyllabic calls, and allowed children to learn their parents' calls by imitating their lip movements.
Functional architecture of the somatosensory homunculus detected by electrostimulation
The analysis of the MNI body coordinates showed rare inter‐individual variations in the medial‐to‐lateral somatotopic organization in these patients with rather different intensity thresholds needed to elicit sensations in different body parts.
Expanded Exploration of the Auditory Naming Test in Patients with Dementia.
The ANT index score adds diagnostic utility to the assessment of naming difficulties in patients with suspected dementia, and is most pronounced in older, well-educated, male patients with the least cognitive impairment.


Comprehension deficits elicited by electrical stimulation of Broca's area.
The patients with intractable focal seizures arising from the language-dominant left hemisphere had severe impairment of comprehension verbal information, in clear contrast with ability to process non-verbal material, which was not affected.
The anatomy of phonological and semantic processing in normal subjects.
Brain activation was assessed in the temporal, parietal and frontal multi-modal association areas that constitute parts of a large network that represent the specific anatomic substrate of the lexico-semantic processing of language.
Evidence for a basal temporal visual language center
These observations support the existence of a visual language area in the dominant fusiform and occipitotemporal gyri, contiguous with basal temporal language area, located posterior to and contiguous with the basal temporal region.
Cortical language localization in left, dominant hemisphere. An electrical stimulation mapping investigation in 117 patients.
There is a need for revision of the classical model of language localization, for it means that language cannot be reliably localized on anatomic criteria alone and a maximal resection with minimal risk of postoperative aphasia requires individual localization of language with a technique like stimulation mapping.
Effective and Structural Connectivity in the Human Auditory Cortex
Combining BOLD fMRI-based GCM and DTPM analysis could provide a novel means to study effective and structural connectivity not only in the auditory cortex, but also in other cortical regions.
Modeling variability in cortical representations of human complex sound perception
The utility of using the statistical modeling approach of Template Mixture Modeling to quantify sources of variability in cortical functional organization in seizure patients undergoing left hemisphere electrocortical mapping is demonstrated.
