This study shows that unilateral carotid artery stenosis reduces interhemispheric BOLD coherence at ~0.1 Hz, especially in watershed areas, suggesting impaired vasomotor activity affects resting-state functional connectivity.

This paper develops a high-resolution awake mouse fMRI platform to map sensory processing in association cortices, revealing anticipatory brain activity during vibrissa stimulation.

This study uses high-resolution MRI to map glymphatic transport in deep brain regions by directly infusing Gd into the lateral ventricle and analyzing PVS signal enhancements.

The paper attempts to replicate DIANA fMRI findings in anesthetized mice but fails to observe direct neuronal activity-like peaks, suggesting potential artifacts or data pre-selection issues.

The paper uses pupillary light response-driven fMRI in awake mice to identify brain-wide biomarkers of Alzheimer's disease by analyzing altered neuromodulatory patterns and functional connectivity.

This paper develops a data-driven method for analyzing fMRI data across studies, revealing consistent patterns in BOLD time series and demonstrating its generalizability and robustness.

This paper introduces a new fMRI method called SELINE to improve laminar-specific BOLD signal detection by reducing vein effects and improving spatial resolution.

StandardRat improves functional connectivity specificity in rat brains through a standardized MRI protocol tested across 20 centers.

This paper develops a multi-slice line-scanning fMRI method to map laminar-specific functional connectivity in anesthetized rats, revealing trial-dependent and layer-specific spatiotemporal patterns of BOLD responses and resting-state signal propagation.

This paper develops an implantable inductive coil detector to enhance focal fMRI signal sensitivity in animal brain imaging, achieving a 2-3 fold increase in tSNR compared to conventional methods.

This paper introduces CBF-fMRI using phase-contrast imaging to map blood velocity in single vessels, showing comparable velocity changes in arterioles and venules.

This paper develops a bilateral line-scanning fMRI method to map laminar-specific interhemispheric connectivity in rodents, revealing layer-specific coherence patterns in the corpus callosum.
