This study optimizes VASO for submillimeter laminar fMRI in the human hippocampus, enabling differentiation of neural activity from vein bias in memory tasks.

The paper investigates whether hemispheric asymmetry in tau pathology in Alzheimer's disease is linked to reduced inter-hemispheric connectivity or asymmetric amyloid-beta distribution, finding a strong association with amyloid-beta laterality.

The paper shows that neural representations of natural concepts in the medial temporal lobe and neocortex are embedded in task-relevant representational spaces that reorganize with task demands and influence memory formation.

The paper investigates visual cortex plasticity in a rare case of optic chiasm hypoplasia, finding three hemifield maps in one hemisphere and suggesting developmental re-wiring supports their function.

This paper introduces micro-probing (MP), a method to map neuronal subpopulation receptive fields in humans using fMRI without prior assumptions, revealing subpopulations in both healthy and diseased states.

The paper investigates visual cortex structure and connectivity in albinism using fMRI and pRF mapping, finding equivalent hemifield representations and altered cortico-cortical connections in V3.

This paper uses diffusion MRI to detect and quantify crossing fiber abnormalities in the optic chiasm of individuals with albinism, showing improved detection with optimized streamline filtering methods.
