This study links human brain functional connectivity to neurotransmitter systems using resting-state fMRI and MEG across multiple cohorts, showing consistent patterns and clinical relevance.

The paper improves fMRI analysis in Parkinson's Disease by integrating kinematic data and event-related modeling to better detect subcortical activations and medication effects.

This paper evaluates the test-retest reliability of task-based and resting-state fMRI and CBF measures in healthy volunteers, finding large variability and suggesting activation extent as a reliability estimate for new paradigms.

This study identifies reproducible functional connectivity alterations in ASD using rs-fMRI across four large cohorts, linking them to clinical symptoms and brain regions.

The paper investigates how cerebral blood flow changes in response to drugs targeting different neurotransmitter systems and finds a reliable spatial link between blood flow changes and receptor densities.
