Generalizable sex differences in functional brain organization follow the cortical hierarchy in youth

The paper examines sex differences in functional brain connectivity across youth, finding that males show greater network integration while females show greater network segregation along the sensorimotor-association axis.

Distinct spatial associations of adversity with hippocampal macro- and microstructure in early adolescence

The paper examines how different types of adversity relate to hippocampal macro- and microstructure in early adolescents, finding distinct spatial associations across brain regions.

Sex-related structural alterations across common epilepsies: a worldwide ENIGMA study

This study examines sex differences in structural brain alterations in common epilepsies using neuroimaging data from a large international cohort, finding some regional differences but no significant sex-by-diagnosis interactions.

White matter reflects the childhood exposome

This study links childhood environmental exposures to white matter structure in children, showing that advantaged environments correlate with larger white matter tracts and reduced orientation dispersion.

Neurodevelopmentally rooted epicenters in schizophrenia: sensorimotor-association spatial axis of cortical thickness alterations

This study identifies neurodevelopmentally rooted epicenters of cortical thickness alterations in schizophrenia, linking them to specific functional regions and genetic factors.

A Multimodal Characterization of Low-Dimensional Thalamocortical Structural Connectivity Patterns

This study identifies two main axes of thalamic organization using multimodal data, linking structural connectivity patterns to microstructural features, functional connectivity, and network organization.

Microstructural asymmetry in the human cortex

The paper examines layer-specific microstructural asymmetry in the human cortex, finding anterior-posterior patterns linked to function and heritability.

Sex differences in intrinsic functional cortical organization reflect differences in network topology rather than cortical morphometry

The paper examines sex differences in functional cortical organization and finds they are linked to network topology rather than cortical morphometry.

A gradual transition toward categorical representations along the visual hierarchy during working memory, but not perception.

The paper shows that during working memory, orientation representations in the visual hierarchy become more categorical compared to perception, with a gradual shift toward categorical formats in more anterior regions.

The spatial arrangement of laminar thickness profiles in the human cortex scaffolds processing hierarchy

The paper quantifies how laminar thickness patterns in the human cortex correlate with processing hierarchy, showing developmental and functional relationships.

An open, analysis-ready, and quality controlled resource for pediatric brain white-matter research

The paper curates and provides analysis-ready diffusion MRI data for pediatric brain white-matter research, including automated quality control using a trained neural network.

Heritability of hippocampal functional and microstructural organisation

This study examines the heritability of hippocampal functional and microstructural organisation in healthy adults using twin data and multimodal neuroimaging.

Multilevel neural gradients reflect transdiagnostic effects of major psychiatric conditions on cortical morphology

The paper identifies a shared cortical morphology dimension across six psychiatric conditions using MRI data from 28,546 participants.
