“…Research to date indicates that class A refers to abstraction, class B to concrete thought, class C to decreased attention with decreased excitation, while the interpretation of class D remains unclear.

For the time being, microstates may be among the most promising notions when using EEG in neuroeducation, as they appear to be suited for the discovery of psychophysiological signatures of cognitive functions responsible for learning (for example, social learning, metacognitive regulation in problem solving, insight in problem solving, implicit and explicit learning, etc.).…”
