This paper identifies and mitigates Fuzzy Ripple artifacts in high-resolution fMRI, enabling sub-millimeter resolution and faster acquisition protocols.

The paper develops acquisition protocols and processing pipelines for whole-brain layer-fMRI and introduces the Kenshu dataset for benchmarking and analysis.

This study compares denoising methods for multi-echo 7T fMRI data, finding that ME-ICA combined with aCompCor and ICA-AROMA is highly effective for noise reduction and signal preservation.

This paper evaluates 3T layer-fMRI VASO for cortical layer-specific functional imaging, finding it feasible for motor tasks despite thermal noise limitations.

The paper addresses real-time fMRI data export challenges, showing delays in data transfer and proposing a solution for Siemens MRI devices that reduces delays and improves quality measures.

This study measures hippocampal perfusion using 7T MRI and finds significant subfield differences, with CA1 having the lowest perfusion, influenced by vascular proximity and cytoarchitecture.

The paper provides a high-resolution T2* MRI dataset of the human brain at 7 Tesla, revealing cortical substructures and consistent depth-dependent T2* values across subjects.

This study investigates neural prediction error signals in aversive learning using fMRI in humans, finding asymmetric representation of threat omission PEs in the medial prefrontal cortex.

The paper introduces MESMERISED, a sequence that accelerates T1 relaxometry and diffusion MRI at 7 T, enabling efficient multi-contrast and diffusion imaging with high resolution and speed.

This paper validates layer-specific VASO fMRI across species by comparing it to optical imaging and MION contrast enhanced fMRI in rats and humans, confirming its reliability for estimating layer-specific CBV changes.

LayNii is a software suite designed for analyzing layer-specific functional MRI data with SNR and coverage constraints, offering tools for layerification, smoothing, and artifact mitigation.

This study demonstrates sub-millimetre resolution laminar fMRI using ASL in humans at 7T, showing perfusion and BOLD signals are consistent despite apparent discrepancies.

This study uses sub-millimeter fMRI to show that individual fingers have multiple mirrored representations in the motor cortex based on movement types, bridging invasive and non-invasive motor organization research.
