Comparative Study
EEG correlation and power during maintenance of wakefulness test after sleep-deprivation.
To investigate whether there are any objective EEG characteristics that change significantly between specific time periods during maintenance of wakefulness test (MWT) and whether such changes are associated with the ability to appropriately communicate sleepiness. ⋯ This study demonstrates that there are specific EEG characteristics associated with impending failure to communicate sleepiness.

Randomized Controlled Trial Comparative Study
Use of swLORETA to localize the cortical sources of target- and distracter-elicited P300 components.
Cognitive event-related potentials (especially P300) have long been used to explore attentional processes. The aim of this study was to identify the cortical areas involved in P300 generation during a selective attention task. ⋯ Our data agree with the literature reports using other methods and should help to improve our knowledge of the cerebral networks underlying attentional processes.
