Summary: Working memory stores information for future use, bridging the gap between perception and behavior. This study finds that when a certain memory representation is useful for guiding behavior, different visual stimuli can be flexibly recoded into the same memory format. These mnemonic representations are abstractions of low-level perceptual features.

Summary: The study shows that divergent subcortical-hippocampal projections play a crucial role in mnemonic processing. Specific projections are necessary for contextual memory and social memory, indicating distinct pathways for different types of memory.

Summary: This study examined the impact of familiarity on precision and accuracy of mnemonic correspondence in visual working memory. The findings revealed that familiarity enhances memory precision but impairs memory accuracy. These results provide insight into the phenomenon of celebrity sightings and underscore the importance of assessing both precision and accuracy in memory research.

Summary: Water interaction with mineral surfaces is crucial for photocatalytic processes. This study investigates the atomistic structure, atomic structure, and surface chemistry of fibrous rutile TiO2 in the presence of water. The results show that the specific interface structure can induce acidic response in a neutral medium.

Summary: This study examines the understanding of memory through an economic lens, showing how the labor of remembering adds value to memories and transforms them. Through embodied memories and imaginaries of migration and belonging, memories are transformed into collective archives and objectified memory forms. The study also demonstrates how the mnemonic labor of participants in making clay hearts can transform memories into new forms of mnemonic capital.

Summary: Recent studies have shown that stimulus history can be decoded and mnemonic representations reactivated using broadband sensory impulses. Additionally, predictive mechanisms allow the brain to form sensory predictions based on previous stimuli and update them when errors occur between model predictions and external inputs. This study recorded neural activity in the auditory cortex of anesthetized rats using electrocorticography and found that both stimulus history and predicted stimuli can be decoded from neural responses to broadband impulses.

Summary: Persistent spiking activity in the neocortex is a neural substrate of working memory, characterized by executive control, limited capacity, and internal manipulation of information. This activity relies on a synaptic theory of recurrent circuits and is consistent with temporal variations and heterogeneity across neurons in a subspace of population activity.

Summary: The traditional dietary assessment tools for determining achievement of cholesterol-lowering targets are time consuming. This study found that the Healthy Eating Assessment Tool (HEAT), a simplified dietary assessment tool, is associated with markers of adiposity and lipid variables. The HEAT may be a more useful and simplified way of assessing and tracking broader dietary goals in clinical practice.

Summary: This study investigated the role of the lateral geniculate nucleus (LGN) in working memory (WM) and found that LGN accurately encodes spatial locations held in memory. These findings suggest that LGN is involved in WM and may be a key pathway connecting memory and early visual processing.

Summary: Closed-loop direct brain stimulation can improve episodic memory, especially when targeted at regions near white matter pathways with high functional connectivity to the brain's memory network. The anatomical and functional network properties of the stimulation target play a crucial role in its behavioral and physiological effects.

Summary: This study aimed to evaluate the effects of an intensive non-surgical weight management program on weight loss and metabolic outcomes in patients with varying degrees of weight-related complications. The results showed that after 12 months of treatment, there was significant weight loss and improvement in metabolic parameters in both groups, regardless of the severity of complications. This suggests that intensive non-surgical weight management programs can be effective in achieving clinically meaningful weight loss in patients with severe obesity.

Summary: Memories are not stored in isolation. Insight into the relationship of initially unrelated events may trigger a flexible reconfiguration of the mnemonic representation of these events. However, stress impairs this process and leads to fragmented memories in PTSD. In this study, acute stress was found to reduce brain activity and disrupt the reconfiguration of memories, but interestingly, it enhanced long-term memory performance. These findings have implications for understanding memory distortions in stress-related mental disorders.

Summary: Our perception of time can be distorted and influenced by various factors, including memory accessibility. Through behavioral and functional MRI measures, we found that event boundaries disrupt memory integration processes and lead to compressed duration judgments. Furthermore, the temporal pattern change in the left hippocampus was associated with longer duration judgments, suggesting that mnemonic processes play a role in constructing representations of time.
