POPE optimizes EPI gradient pulses to reduce peripheral nerve stimulation, enabling high-resolution fMRI without exceeding safety limits.

This study uses MRI to show neural activity drives directional CSF flow in the subarachnoid space near activated brain regions in awake humans.

This study introduces SOPHI, a method to map ultra-slow CSF flow in the human brain, revealing coherent flow patterns linked to vascular anatomy and potential CSF efflux pathways.

This paper introduces a phase-contrast MRI technique to quantify slow cerebrospinal fluid flow in the human brain, showing cardiac pulsation drives brain-wide flow more than respiration.

This paper introduces Romer-EPTI, a novel dMRI technique that improves SNR, motion robustness, and image quality for in-vivo mesoscale imaging.

This paper introduces single-shot Echo Planar Time-resolved Imaging (ss-EPTI) to improve motion robustness, temporal resolution, and SNR efficiency in dynamic imaging applications.

This study uses 7-Tesla fMRI to show that the human periaqueductal grey (PAG) shows bilateral BOLD increases during a working memory task without threat, suggesting a broader role in brain-body communication.

The paper replicates and extends a brain system for allostasis and interoception using 7 Tesla fMRI, finding high agreement with animal tract-tracing studies.

The paper examines spatial patterns of PAG activity and physiological responses during social stress in humans using 7T imaging.

This study uses fMRI to show that the human superior colliculus shows increased BOLD signal during visual and somatosensory stimulation and aversive conditions, correlating with brain regions involved in sensory and interoceptive processing.

This study uses 7-Tesla fMRI to show layer-dependent activity in the human superior colliculus during a working memory task, linking it to visual processing, motor control, and executive function.

The paper evaluates and corrects slice-direction geometric distortion in high-resolution 7T EPI using reversed slice-select gradient acquisitions and gradient reversal-based correction.

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 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.
