Abstract

Because higher-order cognitive functions are supposed to be executed by the interplay between various brain regions, it is necessary to elucidate the neural communication between brain regions to understand the purpose of understanding the mechanism of such brain functions. Therefor, functional connectivity analysis has been rapidly gaining in importance. This is an analysis that illuminates the spatiotemporal dynamics at the whole-brain level based on the functional or effective connections, defined by a statistical correlation or a causal relation of neural activities between brain regions. The present manuscript primarily provides the basic idea of functional connectivity analysis, and then introduces representative methods. Finally, the approaches to the diagnosis of neurological diseases based on this analysis are introduced.
