Mapping the topographic organization of the human zona incerta using diffusion MRI

This study maps the topographic organization of the human zona incerta using diffusion MRI and connectivity analysis, revealing gradients and clusters linked to specific cortical regions and functions.

AFIDs-Validator: An Open-Access AI-Guided Platform for Learning Anatomical Landmark Placement

Open browser platform embeds a language-model neuroanatomy tutor in an MRI viewer and scores landmark placements against 21 expert-annotated templates using trained-rater error distributions.

Mapping the spatiotemporal continuum of structural connectivity development across the human connectome in youth

The paper identifies a spatiotemporal continuum of structural connectivity development in youth, showing a shift from sensorimotor to association connectivity around age 15 and its links to cognition and psychopathology.

An anatomically distinct dopaminergic cell population of the zona incerta as evidence for the human A13 nucleus

The paper identifies a human zona incerta subregion with characteristics of the rodent A13 nucleus using MRI and histology.

Styx: A multi-language API Generator for Command-Line Tools

Styx and NiWrap provide language-native wrappers for command-line tools, reducing complexity in pipeline development and enhancing portability across programming languages and environments.

Magnetic resonance imaging datasets with anatomical fiducials for quality control and registration

The paper releases curated anatomical fiducial placements for MRI datasets to improve image registration quality control and registration accuracy.

An automated BIDS-App for brain segmentation of human fetal functional MRI data

The paper introduces funcmasker-flex, a BIDS App using a 3D U-net to automate fetal fMRI brain segmentation, achieving high Dice scores and reducing manual effort.

Mapping the subcortical connectome using in vivo diffusion MRI: feasibility and reliability

This study assesses the feasibility and reliability of mapping the subcortical connectome using in vivo diffusion MRI tractography and test-retest data from the Human Connectome Project.

Assessing white matter pathway reproducibility from human whole-brain tractography clustering

The paper develops a tool to automatically identify human brain pathways and assess their reproducibility using clustering and evaluation metrics across two datasets.

A framework for evaluating correspondence between brain images using anatomical fiducials

This paper introduces anatomical fiducials (AFIDs) to improve spatial correspondence in brain imaging and demonstrates their effectiveness over traditional voxel overlap metrics.
