title: EEG coherence within the 13-18 Hz band as a correlate of a distinct lexical organisation of concrete and abstract nouns in humans.
abstract: Coherence analysis was applied to the EEG of 19 female participants who had to memorize auditorily presented abstract and concrete nouns. The EEG was recorded from 19 scalp electrodes (10/20 system). Significant differences between both word classes were found only in the beta 1-band (13-18 Hz) whereas the alpha 1-band (8-10 Hz) revealed coherence patterns which were identical for both word classes. These results indicate that the alpha 1-band reflects cognitive processes that were common to both word classes, whereas the beta 1-band seems to be closely related to associative processes and more complex cognitive functions.
