This study uses fast fMRI to identify a temporal sequence of thalamic activity during transitions in behavioral arousal states, linking thalamic dynamics to wakefulness and sleep.

This study demonstrates that high-resolution 7T time-of-flight MRI can image pial arteries in vivo, showing that resolution, not blood flow speed, limits visualization of these vessels.

This paper introduces SE-EPTI, a technique for SE-BOLD fMRI that reduces T2' contamination and improves microvascular specificity, showing graded T2' effects across different acquisition strategies.

The paper presents a high-resolution in vivo whole-brain diffusion MRI dataset with detailed anatomical images and field maps for research and development of dMRI techniques.

The paper investigates how physiological processes like respiration and heart rate can create apparent brain connectivity patterns in resting-state fMRI data, challenging interpretations of functional networks.

The paper presents an ultra-high resolution MRI dataset of an ex vivo human brain and provides it in both native and stereotactic spaces for research and educational use.

The paper describes neuroimaging processing methods for the ABCD Study to extract brain phenotypes from multimodal imaging data.

The paper identifies two closely juxtaposed networks within the default mode network in individuals using high-resolution fMRI and multiple analytical methods.
