Pre- and post-stimulus oscillatory activity between 8 and 12 hertz, referred to as the alpha-band, correlates with conscious visual awareness of stimuli across a variety of psychophysical tasks. Within an EEG-adapted inattentional blindness task, the current study sought to examine whether this relationship holds for conscious awareness of stimuli under conditions of inattentional blindness. Noticing rates of the task-irrelevant unexpected stimulus were correlated with a significant decrease in alpha power over bilateral parietal-occipital areas during the pre-stimulus interval, and a significant decrease in alpha power over parietal-occipital regions in the right hemisphere during the post-stimulus interval. Findings are taken to imply alpha-band neural activity represents a valid correlate of consciousness that is not confounded by task relevancy or the need for report.

8 到 12 赫兹之间的刺激前后振荡活动，称为 alpha 波段，与各种心理物理任务中的刺激有意识的视觉意识相关。在脑电图适应的无意失明任务中，当前的研究试图检查这种关系是否适用于无意失明条件下的有意识的刺激意识。与任务无关的意外刺激的注意率与刺激前间隔期间双侧顶枕区的 alpha 功率显着降低相关，以及刺激后右半球顶枕区的 alpha 功率显着降低- 刺激间隔。
