The paper investigates the cellular and mitochondrial factors influencing regional glucose metabolism in the human cortex using multimodal data integration.

The paper examines network-specific metabolic costs of functional connectivity in the human brain using PET/MR data, revealing differences in metabolic demand across brain networks and changes in Alzheimer's disease.

This study examines how acute psychosocial stress reconfigures brain metabolism and network organization using PET/MRI, revealing changes in the default mode network and its interactions with other networks.

This study evaluates the test-retest reliability of fPET and fMRI during reward processing, finding comparable reliability but differing in target areas and dynamic assessment capabilities.

This paper develops a noise correction method for high-temporal resolution fPET data, showing it improves metabolic connectivity estimation across different scanners and frequency bands.

This paper compares molecular connectivity (MC) and covariance (mCov) methods using fPET data to assess metabolic associations between brain regions, finding that different methods perform better at varying temporal resolutions.
