Cortical networks for working memory and executive functions sustain the conscious resting state in man
TLDR
The results suggest that brain activity during conscious REST is sustained by a large scale network of heteromodal associative parietal and frontal cortical areas, that can be further hierarchically organized in an episodic working memory parieto-frontal network, driven in part by emotions. Expand
Neural Correlates of Simple and Complex Mental Calculation
TLDR
The functional anatomy of the two basic resolution strategies involved in mental calculation, namely arithmetical fact retrieval and actual computation, is revealed, questioning in particular the respective role of language and/or visuospatial cerebral areas. Expand
Functional Anatomy of Spatial Mental Imagery Generated from Verbal Instructions
TLDR
Results provide evidence that the so-called dorsal route known to process visuospatial features can be recruited by auditory verbal stimuli and confirm previous reports indicating that some mental imagery tasks may not involve any significant participation of early visual areas. Expand
Brain activity at rest: a multiscale hierarchical functional organization.
TLDR
Functional connectivity analyses revealed that M1b played a central role in the functioning of the intrinsic system, whereas M1c seems to mediate exchange of information between the intrinsic and extrinsic systems. Expand
Mental navigation along memorized routes activates the hippocampus, precuneus, and insula
TLDR
Investigation of the functional anatomy of mental simulation of routes (MSR) in five normal volunteers found that MSR appears to be subserved by two distinct networks: a non-specific memory network including the posterior and middle parts of the hippocampal regions, the dorsolateral pre-frontal cortex and the posterior cingulum, and a specific mental navigation network.

What is right-hemisphere contribution to phonological, lexico-semantic, and sentence processing? Insights from a meta-analysis
TLDR
The fact that RH participation during lexico-semantic tasks was limited to these executive activations is compatible with the hypothesis that active inhibition is exerted from the LH during the processing of meaning, and is consistent with split-brain studies that found that the RH has a limited lexicon.

Gaussian Mixture Modeling of Hemispheric Lateralization for Language in a Large Sample of Healthy Individuals Balanced for Handedness
TLDR
Results indicate that concordance of hemispheric dominance for hand and for language occurs barely above the chance level, except in a group of rare individuals (less than 1% in the general population) who exhibit strong right hemisphere dominance for both language and their preferred hand. Expand
Shifting from the Perceptual Brain to the Logical Brain: The Neural Impact of Cognitive Inhibition Training
TLDR
Functional imaging shows a striking shift in the cortical anatomy of reasoning from the posterior part of the brain to a left-prefrontal network including the middle-frontal gyrus, Broca's area, the anterior insula, and the pre-SMA. Expand
Neural Correlates of Topographic Mental Exploration: The Impact of Route versus Survey Perspective Learning
TLDR
The results suggest that the right hippocampus involvement would be sufficient when the representation incorporates essentially survey information while the bilateral parahippocampal gyrus would be involved when the environment incorporates route information and includes "object" landmarks. Expand
Cortical anatomy of mental imagery of concrete nouns based on their dictionary definition
TLDR
It is demonstrated that a network including part of the bilateral ventral stream and the frontal working memory areas is recruited when mental imagery of concrete words is performed on the basis of continuous spoken language. Expand
