Summary: It has been traditionally believed that information retrieved from long-term memory (LTM) needs to be brought back into working memory (WM). However, this study demonstrates that retrieval from LTM is possible even when WM capacity is fully occupied. EEG results indicate that retrieving items from LTM while WM is fully engaged enhances the suppression of alpha oscillations, suggesting alternative mechanisms for accessing LTM when WM is fully occupied.

Summary: The debate over whether information in working memory is rapidly forgotten or transferred to long-term memory continues. Research shows that the capacity limit of working memory contributes to subsequent long-term memory failures and holding information in working memory enhances long-term memory encoding. The findings suggest that a limitation in working memory capacity creates a bottleneck for encoding of unique objects, with a relatively large effect size.

Summary: Detection dogs play a crucial role in security and defense sectors, but the frequency of maintenance training is limited by logistical and security constraints. This study aimed to investigate long-term odor memory in detection dogs and the effects of single-target maintenance training on their performance. The results showed that minimal maintenance training using a single target odor can maintain and even improve odor discrimination accuracy, but operational search performance may require more regular training.

Summary: This study investigated the impact of the hippocampus on spatial working memory. The results showed that even slight bilateral damage to the hippocampus can block the formation of working memory in a challenging task.

Summary: This review examines the relationship between working memory consolidation and long-term memory consolidation, discussing proposed models and neural mechanisms, as well as clinical findings. Two hypotheses are proposed to explain the relationship between these processes.

Summary: The study found that task-irrelevant spatial structure can improve working memory, independent of long-term spatial associations and unique to space rather than other features. It also showed that spatial structure can be separated from spatial interference, challenging the theories of 'spatial interference' and 'visuospatial bootstrapping'.

Summary: The intention to remember information substantially improves recall of that information when maintained in working memory, but it does not have the same effect on episodic long-term memory. The differences observed may be attributed to factors such as test delay, list length, and proactive interference.

Summary: This study investigated the changes in visual working memory capacity among individuals who migrated from a low-altitude environment to Tibet (a high-altitude environment) using a lateralized change detection task and event-related potentials analysis. The results showed that long-term exposure to high altitude makes it difficult for individuals to exclude the interference of task-irrelevant information, potentially due to impaired inhibitory control.

Summary: The present experiments provide support for the Binding Hypothesis, which posits that working memory capacity is limited by interference between bindings rather than items. Additionally, they demonstrate the substantial contribution of episodic long-term memory to binding memory when working memory is pushed to its capacity limit. The findings reveal a double dissociation between the contributions of working memory and episodic long-term memory to binding memory, with proactive interference primarily affecting larger set sizes and a distractor-filled delay primarily affecting set size 2.

Summary: Engagement in cognitive activity in adulthood is a key factor for successful cognitive aging. This study demonstrates that intermittent working memory training during adulthood can protect aged animals from the deleterious effects of aging on spatial reference memory.

Summary: This study shows that the hippocampus in mice does not map space as a single coherent physical variable, but rather as a combination of sensory and abstract reference frames determined by the subject's behavioral goal. Different behavioral tasks lead to global remapping in the hippocampus, adapting to different spatial information modalities.

Summary: This study developed an olfactory working memory capacity paradigm to evaluate the memory capacity of Alzheimer's disease mouse models. The results showed that the memory capacity of the 5xFAD mice was similar to wild-type mice in certain task phases, but significantly diminished in capacity testing.

Summary: This study investigates the effects of endogenous substance ouabain (OUA) on the rat's central nervous system under chronic stress. The results suggest that intermittent administration of OUA can alleviate HPA axis abnormal activity caused by chronic stress, by reducing glucocorticoids levels, CRH-CRHR1 expression, and neuroinflammation via decreasing iNOS activity, without interfering with antioxidant enzymes expression. These changes may lead to the rapid extinction of aversive memory in the hypothalamus and hippocampus.

Summary: Previous studies have shown that working memory maintenance contributes to long-term memory formation. This study explored how working memory maintenance adapts when long-term retention is intentional. The results indicate that intentions do not change the mechanisms and strategies of working memory maintenance, but they increase the effects of cognitive load and rewards on delayed recalls.

Summary: Research shows that information in both working memory (WM) and long-term memory (LTM) is represented in a sensory-like code in occipital and parietal cortex. These findings provide new evidence for theories of memory systems and the representation of mnemonic content.
