Journal ArticleDOI
Induced alpha band power changes in the human EEG and attention
TL;DR: Induced alpha power (in a lower, intermediate and upper band) which is deprived from evoked electroencephalograph (EEG) activity was analyzed in an oddball task in which a warning signal preceded a target or non-target.
Journal ArticleDOI
A shift of visual spatial attention is selectively associated with human EEG alpha activity
Paul Sauseng,Wolfgang Klimesch,Waltraud Stadler,Manuel Schabus,Michael Doppelmayr,Simon Hanslmayr,Walter Roland Gruber,Niels Birbaumer +7 more
TL;DR: It was found that prefrontal cortex shows stronger phase coupling with posterior sites that are contralateral to the attended hemifield than ipsilateral sites, and that this posterior modulation of alpha activity is controlled by prefrontal regions.
Journal ArticleDOI
Fronto-parietal EEG coherence in theta and upper alpha reflect central executive functions of working memory.
TL;DR: The results indicate the involvement of prefrontal areas in executive functions reflected by a decrease of anterior upper alpha short-range connectivity and a parallel increase of fronto-parietal long-range coherence mirroring activation of a fronto -parietal network.
Journal ArticleDOI
EEG alpha synchronization and functional coupling during top-down processing in a working memory task
Paul Sauseng,Wolfgang Klimesch,Michael Doppelmayr,Thomas Pecherstorfer,Roman Freunberger,Simon Hanslmayr +5 more
TL;DR: Evidence is provided that during top‐down processing in a working memory task, α power increases at prefrontal but decreases at occipital electrode sites, thereby reaching a state in which α power and frequency become very similar over large distances.
Journal ArticleDOI
Theta band power in the human scalp EEG and the encoding of new information.
TL;DR: TASK-related band power changes in the theta and alpha bands were examined during the encoding of new information in an implicit memory paradigm and showed significantly higher theta power during the encode of those words which could be remembered in the later recall task, compared with words which cannot be remembered later.
