This paper introduces a fast whole-brain MRI protocol for mesoscopic venous imaging in humans, enabling detailed vascular mapping in under seven minutes without contrast agents.

This paper characterizes laminar organization across four visual areas using multimodal data, finding parvalbumin profiles as the most discriminative feature.

This paper characterizes cortical depth-dependent CBV and BOLD hemodynamic responses across stimulus durations using VASO and ME-GRE at 7T in humans, finding that longer durations improve CBV specificity but may reduce efficiency.

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 examines neurodegenerative and functional changes in the cerebellar cortex of m.3243A>G patients using MRI, revealing structural and connectivity alterations linked to cognitive deficits.

The paper compares optode-layout design approaches for fNIRS using individual fMRI data, finding that incorporating more individual MRI data improves signal quality and sensitivity.

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 paper investigates how MP2RAGE sequence parameters affect T1 reproducibility and morphometry across sites, showing that B1+ inhomogeneities significantly impact results and that corrections improve comparability.

This study uses depth-resolved ultra-high field fMRI to show feedback contributes to surface motion perception by revealing depth-specific BOLD signal changes in early visual cortex.

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.
