[Reflection of the type and successfulness of the cognitive activity in the human EEG: application of nonlinear methods in psychophysiology].
The information processing by the human brain was studied in two types of cognitive activity: solving a visual-spatial task and a verbal task. One of the Wechsler tests represented a visual-spatial task, whereas a speed-reading was used as a verbal task. A correlation dimension calculated from the EEG time series, was shown to depend on individual capabilities. Subjects with a higher correlation dimension in frontal brain areas executed more successfully the spatial task.
