EEG Activity During Gaming Playing.

Abstract:
Here, Brain Mappings for the five EEG site recordings exhibiting the highest processing complexity (see Rocha et - Correlating Intelligence and Brain Activity, 6th Ann. Meeting Cognitive Neurosci. Soc., 1999), were used to study the brain activity associated to defined events of two different types of games. These mappings encodethe frequency the different recording sites were selected in the studied population as the site exhibiting one of the highest entropy of correlation with the activity at the other 19 recording sites. Game 1 (G1) was designed to test verbal understanding and associated visual pattern recognition; G2 tested concept association cued by visual images. Verbal understanding (event 1) in G1 was associated with bilateral activation of temporo-parietal areas and of central and right occipital sites; the results of this processing were stored mainly in central frontal areas for latter comparison with visual information (event 2) at bilateral frontal and central sites for decision making (event 3). Visual identification (event 1) in G2 was associated with activation of right parietal and occipital sites and activity at central frontal and occipital and left anterior areas; concept handling (event 2) for decision making (event 3) involved mainly central and frontal areas plus right activity at occipital and central sites.
