POPE optimizes EPI gradient pulses to reduce peripheral nerve stimulation, enabling high-resolution fMRI without exceeding safety limits.

The paper maps mesoscopic vascular networks in the human brain using the BigBrain dataset, revealing non-uniform vascular density related to cortical areas.

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 study uses fMRI to investigate how V1 and hMT+ interact during bistable motion perception, finding stronger feedback coupling in V1 during ambiguous stimuli.

This study uses fMRI to investigate how neural dynamics in the brain resolve ambiguous motion perception, finding distinct interactions between frontal and parietal regions during transitions and sustained perceptions.

This study examines how motor task-induced changes in brain connectivity relate to manual dexterity, finding that dexterous individuals show increased network segregation while low performers exhibit greater 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.

The paper analyzes hand movement patterns during everyday tasks to identify recurring hand configurations and their temporal transitions.

This study uses CBV-sensitive fMRI to quantify columnar organization in human hMT+ for axis-of-motion stimuli, showing higher specificity with VASO over BOLD.
