Enlarging the scope: grasping brain complexity

Abstract

To further advance our understanding of the brain, new concepts and theories are needed. In particular, the ability of the brain to create information flows must be reconciled with its propensity for synchronization and mass action. The framework of Coordination Dynamics and the theory of metastability are presented as a starting point to study the interplay of integrative and segregative tendencies that are expressed in space and time during the normal course of brain function. Some recent shifts in perspective are emphasized, that may ultimately lead to a better understanding of brain complexity.
