Summary: Using intracranial electroencephalography, this study investigated the amygdala, orbitofrontal cortex (OFC), and medial prefrontal cortex (mPFC) and found that they play important roles in the emotion circuit. The three regions showed different emotion-induced responses and interactions. The results demonstrated greater broadband gamma activity in the negative condition, increased beta activity in the amygdala and OFC, and decreased beta activity in mPFC during the emotional picture viewing task. Furthermore, model-based computational analyses revealed unidirectional connectivity from mPFC to the amygdala and bidirectional communication between OFC-amygdala and OFC-mPFC.

Summary: This paper examines the use of asset returns as a proxy for detecting interlinkages in the financial system. The study utilizes a US dataset covering the period from 2002 to 2021, and finds that pairwise returns correlation can indicate interconnectedness in the preliminary stage. The Principal Component Analysis identifies a significant portion of variance and detects the co-movement and highly connected state of the financial market during crises. Granger centrality, tested with pairwise directional variance decomposition, highlights the importance of banks and insurance companies in the US financial system. The paper suggests that policymakers should employ multiple network models to validate and calibrate the list of Systemically Important Financial Institutions (SIFIs).

Summary: The study found that patients with PSD showed specific alterations in the transmission and reception of information in the hippocampal subfields, leading to decreases in inward information flow and increases in outward information flow. Additionally, there were significant correlations between cognitive scores and dFCs in the PSD group related to the hippocampal subfields. Furthermore, dFCs of the hippocampus and its subfields improved the classification between PSD and PSND patients compared to clinical and demographic parameters alone, with high accuracy, sensitivity, and specificity.

Summary: In this study, a structural health monitoring method is proposed for damage localization. It combines a substructuring approach and connectivity analysis of a substructure, aiming to isolate and monitor multiple substructures individually. The health of the substructure is determined by analyzing connectivity variations using multivariate and conditional Granger causality analysis. The proposed method can determine whether the substructure is damaged and locate the damage within the substructure, without the need for a dynamic model of the structure.

Summary: This study combined resting-state functional connectivity and Granger causality analysis to investigate frontostriatal network dysfunction in unilateral acute tinnitus patients with hearing loss. The results showed a general reduction in FC between seed regions in the frontostriatal network and nonauditory areas in AT patients, as well as abnormal effective connectivity in several nonauditory regions. Correlations between disrupted FC/EC and clinical characteristics, especially tinnitus distress-related characteristics, were found in AT patients.

Summary: Stroke disrupts long-range anatomical connections and functional organization of brain networks, leading to abnormalities in functional connectivity. Interhemispheric information transfer is significantly decreased, and stroke induces inter-hemispheric asymmetries, particularly in networks related to attention and language, correlating with impaired performance in multiple behavioral domains.

Summary: Our study compared different oscillatory connectivity measures in revealing interhemispheric interactions between primary motor cortices during unilateral finger movements. While phase-based metrics were effective during the beta rebound period, amplitude correlation metrics showed robust connectivity during both periods. Techniques for estimating the direction of connectivity had limited success, with Granger causality being confounded by differences in signal-to-noise ratio.

Summary: Although single cell RNA sequencing technologies are well developed, acquiring large-scale single cell expression data can still be costly. The study proposes a method of compressing expression profiles from the sample dimension by assigning each cell into multiple pools and demonstrates that expression profiles can be inferred from pool expression data with a overlapping pooling design and compressed sensing strategy. This approach, when combined with plate-based scRNA-seq measurement, maintains superior gene detection sensitivity and individual identity while reducing library costs by half.

Summary: This study used high resolution micro-computed tomography to investigate morphological changes in Acropora corallites, revealing patterns of calcium carbonate deposition during new branch formation and truncated tip repair. The results showed that the volume ratio of calcareous deposits in the axial canal of truncated branches significantly increased within the first three weeks, then returned to initial levels in the following week. These findings demonstrate the temporary storage and remobilization of calcium carbonate for rapid growth in Acropora.

Summary: Depression has a higher incidence in women compared to men, and this study investigated the impact of sex on depressive behaviors and underlying mechanisms using a corticosterone-induced depression model in mice. The results showed sex-specific anxiety and depression behaviors in the model group, as well as differences in protein expression and neurotransmitter levels between male and female mice. These findings enhance our understanding of sex-specific differences in depression and support tailored interventions.

Summary: This study explores the effects of prolonged mask usage on the human brain by analyzing EEG and physiological parameters. The results show that the mean EEG spectral power in alpha, beta, and gamma sub-bands of individuals wearing masks is smaller than those without masks. The performances on cognitive tasks and oxygen saturation level differ between the two groups, while blood pressure, body temperature, and heart rate are similar. The analysis also reveals that the occipital and frontal lobes exhibit the greatest variability in channel measurements.
