An illustration of EEG during working memory tasks

Illustration of EEG synchronization during visual working memory task (Kawasaki,Kitajo, Yamaguchi 2010,2014)

A coupled nonlinear oscillator model was proposed to explain a mechanism of the observed EEG theta and alpha synchronization during working memory tasks. This study suggests a possible neuronal entity for flexible and creative thinking of the brain through a variety of phase-phase coupling among distant brain areas.
