The paper shows that BOLD signal changes can oppose oxygen metabolism in 40% of voxels, particularly in the default mode network, challenging the canonical interpretation of fMRI.

This study shows that lateral ventricle volume oscillations drive CSF flow and clearance, influenced by cortical blood-volume changes and physiological drivers.

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 study uses combined PET/MR imaging to show that visual stimulation in humans increases glucose metabolism more than oxygen consumption in visual regions, while other cortical areas show oxidative downregulation.

The paper investigates the energetic costs of neuromodulator signaling in the human brain and finds that evolutionarily novel connections have higher energetic costs than sensory-motor pathways.

This study evaluates how flow compensation and QSM reconstruction methods affect venous susceptibility measurements, finding that QSM methods have a larger impact than acquisition sequences.

This study investigates brain activity changes during migraine cycles, finding cyclic perfusion in the limbic circuit and hypothalamic connectivity shifts, suggesting the hypothalamus drives migraine attacks by losing control over the limbic system.
