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.

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.
Mental navigation along memorized routes activates the hippocampus, precuneus, and insula
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.
Gaussian Mixture Modeling of Hemispheric Lateralization for Language in a Large Sample of Healthy Individuals Balanced for Handedness
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.
What is right-hemisphere contribution to phonological, lexico-semantic, and sentence processing? Insights from a meta-analysis
Brain activity at rest: a multiscale hierarchical functional organization.
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.

Neural Correlates of Topographic Mental Exploration: The Impact of Route versus Survey Perspective Learning
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.

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.
