The paper investigates task-evoked BOLD fMRI deactivations and finds that they do not correlate with decreased glucose consumption, suggesting metabolic stability or increase in these regions.

The paper examines how aging affects cerebral glucose metabolism by analyzing spectral properties of resting-state fMRI signals and identifies a subset of older adults with divergent patterns linked to white matter pathology.

The paper shows acute hyperglycemia increases non-oxidative glucose consumption in specific brain regions without altering cerebral blood flow or oxygen metabolism.

The paper predicts [18F]FDG PET parameters using rs-fMRI and 15O PET data, showing rs-fMRI and CMRO2 explain 45% of Ki variance.

This paper develops a model for improving precision in measuring brain oxygen utilization using [15O] tracers and PET, showing that IDIFs provide more reliable results than AIFs.
