Functional connectivity analysis

Definition

Functional connectivity analysis is a neuroimaging technique used to assess the temporal correlation between different brain regions, helping to understand how these areas communicate and work together during various tasks or in resting states. This method is particularly valuable in examining the brain's functional architecture, revealing insights into network dynamics, and providing a foundation for personalized approaches in psychopharmacology and drug research.
