The paper uses MVPA to decode ocular dominance columns in V1 across cortical layers using BOLD and CBV-fMRI, finding that macrovascular contributions limit spatial specificity.

This study compares gradient echo and spin echo BOLD signals in human V1 cortex at 7 T, finding that spin echo improves spatial specificity but both techniques show reduced specificity toward the pial surface.

This study uses 7 Tesla fMRI to show that 11-12-year-old children and adults have topographic brain responses tuned to numerical quantities, similar to adults.

This study uses ultra-high-field fMRI to reveal layer-specific responses in the human spinal cord during heat-pain stimulation, identifying phasic and tonic response components in dorsal horn layers.

This study benchmarks four cervical spinal cord RF coils at 7 T MRI across multiple centers, identifying performance differences and proposing a standardized evaluation protocol.

The paper identifies spatiotemporal dynamics of feedforward and feedback signals in human visual cortex using fMRI and EEG, revealing their functional roles in object perception.

This paper replicates a laminar dissociation in human dlPFC during working memory tasks but finds no deep-layer activation during response execution, refining models of laminar organization.

The paper introduces a method to map short association fibre connectivity in the human brain using diffusion MRI, showing SAF preserve cortical functional topology and enabling non-invasive insights into cortico-cortical integration.

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 uses high-resolution MRI to show that thin and thick stripes in human V2 have lower myelination compared to surrounding gray matter.

This study benchmarks three MRI sequences to differentiate feedforward and feedback signals in human V1 cortex, finding SE-BOLD provides the best depth-dependent separation.

This study uses 7 T fMRI to test the tripartite model of subthalamic nucleus organization in healthy volunteers and finds no evidence for functionally distinct subregions.

The paper links MRI relaxation rate in substantia nigra to iron concentration in dopaminergic neurons, enabling early Parkinson's disease detection.

The paper shows that left ventral MGB modulation increases during speech recognition in noisy conditions compared to clear speech or speaker identity tasks.

The paper investigates how multisensory and attentional influences vary across cortical depth in sensory cortices using fMRI, finding distinct depth-dependent patterns in auditory and visual cortices.
