Aberrant Modular Dynamics of Functional Networks in Schizophrenia and Their Relationship With Neurotransmitter and Gene Expression Profiles.

ABSTRACT: Numerous studies have emphasized the time-varying modular architecture of functional brain networks and its relevance to cognitive functions in healthy participants. However, how modular dynamics of resting-state functional networks change in schizophrenia and how these alterations relate to neurotransmitter and transcriptomic signatures have not been well elucidated. We harmonized resting-state fMRI data from a multi-site sample including 223 patients and 279 healthy controls and applied the multilayer network method to estimate the regional module switching rate (flexibility) of functional brain connectomes. We examined aberrant flexibility in patients relative to controls and explored its relations to neurotransmitter systems and postmortem gene expression. Compared with controls, patie
