Reproducible Brain Charts: An open data resource for mapping brain development and its associations with mental health

The paper introduces Reproducible Brain Charts (RBC), an open data resource integrating brain development data from 6,346 youth, showing the benefits of harmonized phenotypes and reproducible processing for studying psychopathology.

Moving Beyond Processing and Analysis-Related Variation in Neuroscience

The paper evaluates the impact of different preprocessing pipelines on functional MRI reproducibility and shows moderate inter-pipeline agreement, affecting brainwide association study consistency.

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.

Is it Time to Switch Your T1W Sequence? Assessing the Impact of Prospective Motion Correction on the Reliability and Quality of Structural Imaging

This study compares two MRI sequences, MPRAGE and MPRAGE+PMC, finding that MPRAGE+PMC offers higher intra-sequence reliability but lower quality control metrics compared to MPRAGE.

U-Net Model for Brain Extraction: Trained on Humans for Transfer to Non-human Primates

The paper develops a transfer-learning U-Net model for brain extraction in non-human primates using human data, achieving better performance than traditional methods and popular MRI packages.

Measurement Reliability for Individual Differences in Multilayer Network Dynamics: Cautions and Considerations

This paper evaluates test-retest reliability of multilayer network measures in neuroimaging, identifying methodological factors affecting reliability and task-specific requirements.

Evaluating fMRI-Based Estimation of Eye Gaze during Naturalistic Viewing

This paper validates a method to estimate eye gaze from fMRI during naturalistic viewing and identifies head motion as a key factor affecting its accuracy.

Structural and functional MRI from a cross-sectional Southwest University Adult lifespan Dataset (SALD)

The paper presents a dataset of structural and functional MRI scans from 494 adults to study brain development and aging.

A large, open source dataset of stroke anatomical brain images and manual lesion segmentations

The paper introduces ATLAS, a dataset of 304 T1-weighted MRIs with manual lesion segmentations to improve lesion segmentation algorithm accuracy.

Age and sex modulate the variability of neural responses to naturalistic videos

The paper investigates how age and sex affect neural response variability to naturalistic videos in a large developmental sample, finding increased variability with age and sex differences in young participants.

An open resource for transdiagnostic research in pediatric mental health and learning disorders

The paper introduces the Healthy Brain Network (HBN) biobank, a large-scale multimodal dataset for pediatric mental health and learning disorders research, with initial data release.

An open resource for nonhuman primate imaging

The paper introduces PRIME-DE, an open resource for non-human primate MRI data, aggregating 13 datasets from 11 sites across 98 macaques.

The Healthy Brain Network Serial Scanning Initiative: A resource for evaluating inter-individual differences and their reliabilities across scan conditions and sessions.

The paper provides a resource to evaluate test-retest reliability of functional connectivity across different scan conditions and sessions in a healthy brain network.
