Selection of Two Identical Pictures from a Group of Similar Ones. II: Changes in Ongoing EEG Activity

Popis výsledku v původním jazyce

The paper presents finding of an experiment the aim of which was to judge the impact of an instant cognitive activity (identical pictures searching) on behavior of ongoing EEG activity. Two types of mental task were used: The first - passive watching ofa blank white oval and the second - active searching for identical pictures in a group of similar nine-drawings of living individuals or inanimate objects filling out the white oval. Presented results showed that higher mental load pertinent to active searching for identical pictures in a group of similar pictures results in the prominent event-related desynchronization (ERD) - the mean Total Power value, a quantitative measure of ERD extent, in comparison with reference level (passive watching) was lower while solving the mental task. The results also showed that the actual mental task performance affects the ERD only at some scalp-recording sites. The mean EEG Total Power significantly decreases at parietal and frontal scalp-recording
