Neuroimaging has provided a unique opportunity to obtain comprehensive structural and functional maps related to a wide range of behavioural and cognitive functions. Because of the comprehensive coverage, it is now possible to study how parts of the brain work together to support mental operations. The goal of
connectivity modeling, loosely defined, is to quantify the interrelations among brain areas and how these vary depending on mental processes. My talk will provide an overview of the
historical developments in this area, their contribution to understanding brain function, and recent advances that more explicitly model spatiotemporal interactions and "input-output"
models that chain stimulus-based effects to behavioural output.
