 Neocortical Dynamics, EEG, and Cognition

Show Summary Details


EEG dynamic behavior is closely correlated with cognitive processing. If a (partly) valid physiologically-based dynamic theory of EEG is developed, an indirect connection between physiology and psychology will be achieved. This chapter presents a general conceptual framework in which cell assemblies are pictured as embedded in the global synaptic action fields generating EEG. A simple standing wave model of neocortical global fields is outlined that is consistent with both large-scale (EEG) data and established physiology and anatomy. The global model fits naturally with complementary network models, consistent with the suggested co-existence of networks and global fields. “Binding by resonance” is discussed, in which several networks and/or global fields strongly interact in select frequency bands even when they are only weakly connected. This general view of the “binding problem” of brain science fits well with observations of cognitive events revealing EEG signatures in select frequency bands.

Keywords: neocortical dynamics; connecting physiology to psychology; standing waves; binding by resonance; global fields; synaptic action density
