This study links mitochondrial complex I levels to task switching performance and BOLD response using PET and fMRI in healthy humans.

This study investigates the relationship between spontaneous brain activity (ALFF) and presynaptic density (measured by [11C]UCB-J PET) in schizophrenia, finding group differences in their correlation.

The paper uses induced pluripotent stem cell-derived cortical neurons from early Alzheimer's patients to show that cellular vulnerability to amyloid-beta correlates with clinical vulnerability.

This paper applies Aligned-UMAP to longitudinal biomedical datasets to reveal time-dependent patterns and provides best practices for its use.

This study investigates how Tau pathology in early Alzheimer's disease affects neurophysiological network dynamics using MEG and PET scans, finding frequency-specific correlations between Tau levels and network efficiency and segregation.

This study evaluates the accuracy and reliability of specific binding estimates for [11C]PBR28 using the SIME method, showing good precision and reliability for VS but variability in BPND.
