Summary: Humans can vividly recall and re-experience events from their past, known as episodic or autobiographical memories. fMRI experiments associate autobiographical event recall with activity in default brain regions. Recent study shows that sustained effects during autobiographical recall primarily involve default network regions, while neural activity associated with recalling specific details is transient and broadly distributed across category-selective cortex.

Summary: Cross-modal hashing facilitates relevant sample retrieval across modalities by mapping heterogeneous multimedia data into Hamming space, which is of great research interest due to its rapid retrieval and low storage cost. However, the utilization of modality-specific and modality-shared information for retrieval in existing semi-supervised cross-modal hashing methods has not been well investigated. In this paper, a novel approach called Modality-specific and Cross-modal Graph Convolutional Networks (MCGCN) is proposed to address this issue.

Summary: This study investigated the neural mechanisms of cross-modal prediction by combining an audiovisual sequence memory task, fMRI, and multivariate neural representational analyses. The results showed a reliable cross-modal predictive effect, with stronger predictions from visual to auditory than auditory to visual. The superior parietal lobe (SPL) exhibited higher pattern similarity for visual-to-auditory pairs and mediated the neural pathway from visual to auditory cortex in the VA condition.

Summary: The study demonstrates that the activity patterns of the hippocampus in recalling recent events differ from remote events, supporting predictions of the standard model of consolidation. By utilizing overt spoken recall, researchers found that the posterior hippocampal regions exhibit more active patterns during the recall of recent events.

Summary: This paper presents a novel learning strategy that leverages self-supervision to significantly enhance class activation maps (CAMs) in a multi-modal image scenario. The proposed method effectively improves the performance of the model through the introduction of equivariant terms in the loss function and KL-divergence, and outperforms relevant literature on multiple datasets.

Summary: Understanding cortical topographic organization and how it supports complex perceptual and cognitive processes is a fundamental question in neuroscience. Utilizing naturalistic stimuli, this study identified principal movie gradients that delineate separate hierarchies anchored in sensorimotor, visual, and auditory/language areas. These findings provide an ecologically valid representation of the principles underlying cortical organization in multimodal, dynamic perceptual and cognitive processing.

Summary: Through two experiments, the study found that memories play a significant role in empathy, as participants' experiences in empathetic tasks can trigger the reactivation of their autobiographical memories, leading to heightened emotional responses.

Summary: The existence of mirror neurons in the human brain is largely inferred from indirect non-invasive measurements like functional MRI, based on previous findings in several monkey brain regions. However, the overall usefulness of fMRI adaptation to demonstrate mirror neuron activity in the human brain remains unclear. Therefore, further research is needed to validate the activity of mirror neurons in the human brain.

Summary: This paper proposes a multi-label modality enhanced attention-based self-supervised deep cross-modal hashing (MMACH) framework. It integrates significant features from cross-modal data into multi-label feature representations to improve completion and introduces a multi-label cross-modal triplet loss to measure semantic similarity. Experimental results demonstrate the effectiveness and efficiency of MMACH on multi-label cross-modal datasets.

Summary: This study investigates the contribution of the hippocampal formation and neocortex to declarative memory and finds that their contributions vary depending on the encoding associations used. Functional magnetic resonance imaging results show common activity in the posterior parietal cortex, particularly the precuneus, during all three types of encoding associations. Additionally, the retrosplenial cortex is active during recall of spatial and autobiographical associations, while the hippocampus is only activated during recall of autobiographical associations. These findings support the critical role of the precuneus in episodic memory storage and retrieval.

Summary: Insufficient sleep is associated with impaired hypothalamic activity and declined attentional performance. This study found that near-infrared (NIR) laser therapy can alleviate the effects of sleep deprivation on the hypothalamus, enhance antioxidant status, suppress neuroinflammation, and regulate cellular activity.

Summary: Mood disorders caused by chemotherapy have become more important as cancer patients' survival increases. This study used methotrexate to induce mood disorders in rats and found that treatment with the antioxidant N-acetylcysteine (NAC) can alleviate anxiety and depression-like behaviors, increase antioxidant capacity, reduce oxidative stress and inflammatory response, and regulate brain chemistry. The findings suggest that NAC treatment could be an effective strategy in revising the treatment for individuals suffering from chemotherapy-induced mood disorders.

Summary: This study systematically investigated the effects of extremely low intensity HF-rTMS on cognition in mice and found that 40 Hz rTMS significantly impaired exploratory behavior and spatial memory at both 10 mT and 1 mT conditions. Additionally, 40 Hz stimulation had remarkably different effects on exploratory behavior depending on intensity, compared to 10 Hz stimulation.

Summary: This study examined the efficacy of tDCS for PTSD and related symptoms, as well as the factors that may predict response to tDCS. The results showed that tDCS had a positive effect in reducing symptoms of PTSD, depression, anxiety, and anhedonia. The severity of symptoms at baseline may also predict the response to tDCS.

Summary: Aggression can have serious consequences, but little is known about its personality and neurological origins in children. This study investigated the relationship between self-esteem, aggression, and brain structure in healthy children, and found that self-esteem was negatively associated with aggression. The study also revealed that increased cortical thickness in certain brain areas may be a potential mechanism linking low self-esteem to aggression in children.

Summary: Food deprivation can lead to neurological dysfunctions, including memory impairment. This study used Aplysia as an animal model to investigate the memory deficits caused by prolonged food deprivation. The results showed that 14 days of food deprivation decreased the level of 5-HT in the hemolymph, which contributed to the lack of sensitization and its cellular correlates. However, exogenous application of 5-HT partially induced sensitization in the food deprived animals.

Summary: The study found that intervention with the dual orexin receptor antagonist suvorexant did not have the expected effects on extinction memory and sleep. Higher percentages of REM sleep were associated with poorer extinction memory recall and stronger fear responses. Additionally, the fear extinction training protocol used in this study did not lead to complete fear extinction.

Summary: In this study, a systematic assessment indicator was developed to objectively evaluate hindlimb motor function recovery in rats after thoracic contusion SCI. By screening CatWalk XT gait parameters and using exploratory factor analysis, 38 suitable parameters for assessing motor function were identified. A reliable Coordinated Function Index (CFI) was proposed based on these parameters and simplified for improved assessment efficacy.
