A fundamental shift is occurring in neuroscience and related disciplines. In the past, researchers focused on functional specialization of the brain, discovering complex processing strategies based on convergence and divergence in slowly adapting anatomical architectures. Yet for the brain to cope with ever-changing and unpredictable circumstances, it needs strategies with richer interactive short-term dynamics. Recent research has revealed ways in which the brain effectively coordinates widely distributed and specialized activities to meet the needs of the moment. This book explores these findings, examining the functions, mechanisms, and manifestations of distributed dynamical coordination in the brain and mind across different species and levels of organization. It identifies three basic functions of dynamic coordination: contextual disambiguation, dynamic grouping, and dynamic routing. The book considers the role of dynamic coordination in temporally structured activity and explores these issues at different levels, from synaptic and local circuit mechanisms to macroscopic system dynamics, emphasizing their importance for cognition, behavior, and psychopathology.Less

This chapter focuses on dynamic coordination, how it is mechanistically implemented in brain circuits, and the extent to which it accounts for functions performed by interacting brain systems. It also discusses how modulation of phase relationships of oscillations in different brain systems, in neocortex and hippocampus of the mammalian brain, may alter functional coupling; possible mechanisms for oscillation-based synchronization, particularly in the gamma frequency range; coordination by gain modulation and by synchronization of oscillation patterns; and the role of long-range projecting interneurons in synchronizing one neural circuit with another. Finally, the chapter considers how oscillations may influence dynamic routing within structurally constrained brain networks.Less
