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 motor cortex microstructure in humans and chimpanzees using qMRI, finding conserved high myelin and iron content in the hand-knob but enhanced rightward lateralization in humans.

This study shows that vascular draining affects laminar decoding in fMRI and that deconvolution can improve specificity but not fully resolve ambiguities.

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 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.

This study examines layer-specific responses in the dlPFC during a working memory task using fMRI, finding differential activation patterns in superficial and deep layers across task phases.

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 shows that the magnitude PSF does not accurately represent the effects of k-space sampling and signal decay on spatial resolution in fMRI and proposes improved approximations.

The paper estimates the spatial specificity of BOLD fMRI responses using ocular dominance columns, finding PSF full-widths at half-maximum of 0.82 mm (SE) and 1.02 mm (GE).
