TLDR
This paper examined the effect of focal brain lesions on three new tasks, a modification of the previously-used Hotel task, a new test of task switching after extended delays, and a test of decision-making in imagined real-life scenarios.About:

Spatially-embedded recurrent neural networks reveal widespread links between structural and functional neuroscience findings
TL;DR: In this paper , a spatially-embedded recurrent neural network (seRNN) is proposed to learn basic task-related inferences while existing within a 3D Euclidean space, where the communication of constituent neurons is constrained by a sparse connectome.

Neural Contributions to Reduced Fluid Intelligence across the Adult Lifespan
TL;DR: In this paper , the authors show that age-related differences in fluid intelligence are partially mediated by the responsiveness of frontoparietal regions to novel problem-solving, but not with voxels suppressed by cognitive demand.

Neural contributions to reduced fluid intelligence across the adult lifespan
TL;DR: In this article , the authors show that age-related differences in fluid intelligence are partially mediated by the responsiveness of frontoparietal regions to novel problem-solving, and that this mediation model is moderated by the variety of regular physical activities, more reliably than by their frequency or duration.

Deficits in strategy application following frontal lobe damage in man
Tim Shallice,Paul W. Burgess +1 more
TL;DR: A quantitative investigation of the ability to carry out a variety of cognitive tasks was performed in patients who had sustained traumatic injuries which involved prefrontal structures, and it is argued that the problem arose from an inability to reactivate after a delay previously-generated intentions when they are not directly signalled by the stimulus situation.

TL;DR: Nine previous positron emission tomography studies of human visual information processing were reanalyzed to determine the consistency across experiments of blood flow decreases during active tasks relative to passive viewing of the same stimulus array.

Remembering the past and imagining the future: common and distinct neural substrates during event construction and elaboration
TL;DR: A striking neural overlap in regions comprising the autobiographical memory retrieval network is consistent with findings that amnesic patients exhibit deficits in both past and future thinking, and confirms that the episodic system contributes importantly to imagining the future.

Experience sampling during fMRI reveals default network and executive system contributions to mind wandering
TL;DR: An fMRI study that used experience sampling to provide an online measure of mind wandering during a concurrent task revealed a number of crucial aspects of the neural recruitment associated with mind wandering, highlighting the value of combining subjective self-reports with online measures of brain function for advancing the understanding of the neurophenomenology of subjective experience.
