TL;DR: Reliability and similarity of resting-state functional connectivity can be greatly improved by increasing the scan lengths, and that both the increase in the number of volumes as well as the length of time over which these volumes was acquired drove this increase in reliability.

TL;DR: The hypothesis that the process of relational integration, or considering multiple relations simultaneously, is a component process of complex reasoning that selectively recruits PFC is tested and left RLPFC showed the greatest specificity by remaining preferentially recruited during 2-relational problems even after comparisons were restricted to trials matched for RT and accuracy.

TL;DR: Increasing the amount of to-be-maintained information, without any overt manipulation requirement, resulted in the recruitment of wide-spread frontal-lobe regions.

TL;DR: Results demonstrate frontal-lobe specialization in maintaining working-memory representations that integrate verbal and spatial information that demands flexible mental representations.

TL;DR: Brain activation, as measured by functional magnetic resonance imaging, during problem solving in seven young, healthy participants is examined to suggest that fluid reasoning is mediated by a composite of working memory systems.
