Summary: Cognitive control guides behavior by controlling what, when, and how information is represented in the brain. Prefrontal cortex acts as a domain-general controller for both selection and attention, while parietal and visual cortex represent attention and selection independently. Selection and attention facilitate behavior by enhancing and transforming the representation of selected memory or attended stimulus.

Summary: This study investigates the relationship between working memory and attention using fMRI and machine learning. The results demonstrate that selecting items in working memory and shifting attention utilize similar neural mechanisms. These shared mechanisms control the relative gains of neural populations and encode behaviorally relevant information.

Summary: This study discusses three ways in which information becomes automatically prioritized in working memory: physical salience, statistical learning, and reward learning. It integrates findings from perception and working memory studies to propose a more sophisticated understanding of the relationship between attention and working memory.

Summary: This study investigates the neural basis of working memory capacity by exploiting the content dependence of memory materials. The results show that alpha oscillations track memory capacity in a content-specific manner, dependent not only on the number of items but also on their complexity.

Summary: The study identified two top-down attentional control processes that have opposing effects on distractor resistance. An early selection negativity was found in EEG responses to matching distractors, and congruency effects were positively associated with distractor resistance.

Summary: The study found that working memory training has a certain impact on the morphology of the brain, mainly manifested in increased cortical gyrification, volume and thickness, as well as changes in surface area. Particularly, the affected brain regions, especially the parietal regions, may provide a better brain processing environment for higher working memory load.

Summary: This study reveals that participants tend to remember an ambiguous directional cue as biased towards stimuli associated with a high reward, especially those that can be obtained through dishonest means. This research offers important constraints for theories in behavioral ethics, providing initial evidence of a link between attention, dishonesty, and memory.

Summary: Previous studies have shown that high-level cognitive functions such as attention can modulate the tilt aftereffect (TAE), but it is unclear whether working memory load has an effect on TAE. Two experiments were conducted, with one showing a reduction in TAE magnitude under high working memory load when digits were used as load stimuli, while the other experiment did not replicate this finding when color-shape conjunctions were used as load stimuli. Further replications are needed to clarify the effects of working memory load on TAE.

Summary: Recent research has explored the phenomenon of working memory (WM)-guided attention, which directs attention to external information matching WM content. Little is known about the nature of this attention system, which exhibits characteristics of both exogenous and endogenous attention. Two experiments were conducted, one with an exogenous cue and the other with an endogenous cue, to test the mechanism of WM-guided attention. The findings suggest that WM-guided attention shares mechanisms with exogenous attention and operates in parallel with endogenous attention.

Summary: The study suggests that different phases of the menstrual cycle can affect the brain activation and connectivity patterns in women, especially during verbal working memory tasks. Variations in hormone levels during different phases may lead to changes in top-down regulation of the brain, affecting cognitive function and neural network activity.

Summary: Working memory deficits are important in ADHD, but they are not universal and may vary based on different components of working memory capacity. Complex working memory operations may be impaired in ADHD compared to simpler operations, and there are differences in neural activation between ADHD and neurotypical individuals under higher loads and greater complexity.

Summary: The study found that object-based selection is stronger than feature-based selection in attention mechanisms, and a similar pattern exists in memory updating. This indicates the presence of object-based attention effects in visual working memory, suggesting shared attentional mechanisms between perception and memory.

Summary: Adolescence is a transitional stage with increased risk taking and mood dysregulation, which can be explained by the triadic functional brain networks underlying reward seeking, emotional avoidance, and cognitive regulation. The study found that reward seeking and emotional avoidance mostly exhibited quadratic functional connectivity changes across age, while cognitive regulation showed both linear and quadratic changes.

Summary: The study found that implementation intention reappraisal can reduce negative emotions and bilateral amygdala activity without increasing cognitive efforts. This emotion-regulatory effect is achieved through the automatization of emotion regulation by implementation intention, reducing the online mobilization of emotion-coping neural systems.

Summary: This research studied the charging process of a solar power latent heat thermal energy storage system with a bionic leaf venation design. By establishing transient 3D models and analyzing the impact of venation structure extension at different positions, it was found that the extension and position on the Z axis have significant effects on heat diffusion. The optimal distance for improving thermal consistency was speculated to be between 1 and 2 mm from the bottom.

Summary: This study examined the differences in structural connectivity between the locus coeruleus (LC) and the thalamus in younger and older adults using high-resolution diffusion tensor imaging-based tractography. The results showed that LC projections degrade with age, and the extent of degradation is associated with cognitive abilities in older adults.

Summary: Self-deception is a biased cognitive process that involves obtaining or maintaining false beliefs to enhance or diminish oneself. Studies have shown that self-deception is more likely to occur when faced with easier cheating opportunities, and it is associated with changes in frontal slow wave amplitude and activity in the anterior medial prefrontal cortex.

Summary: This study analyzed the effect of porosity distribution on the heat transfer performance of shell-and-tube thermal energy storage systems. The results showed that increasing porosity gradient improved the melting rate and average heat transfer rate. The average heat transfer rate increased by 21.6% when the porosity gradient increased along the positive y-direction. Increasing porosity gradient along the outer radius direction improved the heat transfer near the heating wall but slowed down the phase change process near the outer wall. The maximum average heat transfer rate was achieved at epsilon = 0.88 + 0.6r.

Summary: Hidden Markov Models (HMMs) are commonly used to analyze neuroimaging data and identify recurring patterns. However, most existing HMMs define states based on activity levels rather than functional connectivity patterns. In this study, we introduced a new HMM that defines states based on full functional connectivity profiles, which outperformed previous methods in accurately identifying connectivity states.
