Functional dissociation of place and spatial view codes in primate hippocampus

This study demonstrates that the primate hippocampus contains distinct, coexisting populations of position, view, and conjunctive cells, resolving the debate over species differences by showing that robust rodent-like place codes exist in primates but were previously overlooked due to methodological and task-related factors.

Mechanistic Study of Deoxyshikonin-Mediated Protection Against High-Glucose-Induced Injury in HUVECs

This study demonstrates that deoxyshikonin (3 µM) protects human umbilical vein endothelial cells from high-glucose-induced injury by restoring angiogenic capacity and modulating the expression of key downstream effectors, including IFITM1, THY1, CCBE1, CCL2, and ENTPD1, through pathways involving extracellular matrix organization, inflammation, and angiogenesis.

Overt intentions for answers Yes and No are influenced by feedback and context

This study introduces an "Akinator"-inspired experimental paradigm to demonstrate that neural signatures of binary mental agreement and disagreement, including P3a and N270 components, are significantly modulated by feedback, stimulus context, and presentation sequence, thereby advancing the development of BCI communication and verification systems.

Low-dimensional factorized neural computations underlie risk-adaptive choices

This study demonstrates that risk-adaptive decision-making relies on low-dimensional neural computations that segregate safe and risky states, a mechanism identified through deep reinforcement learning agents and validated by similar dynamical patterns in human neuronal recordings.

EEG-Based Identification of Hidden Functional Topography Changes in Major Depressive Disorder

This study utilizes resting-state EEG data from the MODMA dataset to demonstrate that Major Depressive Disorder is characterized by specific alterations in signal complexity and functional network topology, particularly involving reduced integration and increased segregation in frontal, parietal, temporal, and occipital regions, thereby establishing these metrics as promising objective neurophysiological biomarkers for the disorder.

A Patient-Derived Xenograft Model Identifies AK1 as a Key Regulator of Metastatic Potential in Primary Triple-Negative Breast Cancer

This study utilizes patient-derived xenograft models to demonstrate that adenylate kinase 1 (AK1) is a critical regulator of metastatic potential in primary triple-negative breast cancer by driving hypoxia-associated metabolic reprogramming and supporting tumor cell survival and migration.

City-specific or generalisable resistances? An urban animal connectivity model performs better when parameterised from two cities

By analyzing common blackbird movement in Munich and Angers, this study demonstrates that while absolute habitat resistance values vary between cities, combining data from multiple urban environments significantly improves the predictive accuracy and transferability of connectivity models for identifying relative barrier importance.

Latent HIV Infection of BBB Pericytes Disrupts Gap Junction-Mediated Crosstalk with Endothelial Cells

This study demonstrates that HIV-1 infection of BBB pericytes, whether active or latent, disrupts endothelial cell integrity by enhancing gap junction-mediated communication, thereby driving neuroinflammation and contributing to HIV-associated neurocognitive impairments.
