Cover Story: While EEG alpha desynchronization has been related to orienting of visuospatial attention, its synchronization would index an inhibition of attentional processes. Research has indicated that alpha is also affected by a deficient brain oxygenation (hypoxia). In this study, alpha power during attention alerting, cued and uncued orienting, and control functions in different workload conditions was monitored both in normoxia and hypoxia in healthy students. Independent of oxygenation level, alpha desynchronization was maximal during uncued attentional orienting, whereas hypoxia enhanced alpha synchronization over the right-sided occipitoparietal areas. We interpreted such right-sided modulation as a marker of the suppression of attentional processing induced by hypoxia. View this paper.
