本研究调查的问题是否好的和坏的性能在视觉辨别任务是以不同的方式与静息阿尔法功率，因为它是从记忆任务。结果表明，良好的知觉而不是记忆表现与低α振幅有关。此外，我们发现，在α波段大的相位重置，增强早期成分的ER-P与良好的性能在歧视的任务。本研究的结论是，与与大的静息α活动相关的记忆性能相反，低α振幅是良好感知性能的指标。(C)2004爱思唯尔爱尔兰有限公司保留所有权利。
This study investigated the question whether good and bad performance in a visual discrimination task is related to resting alpha power in a different way as it is known from memory tasks. The results show that good perceptual but not memory performance is related to low alpha amplitudes. In addition, we found that large phase resetting in the alpha band, and enhanced early components in the ER-P are related to good performance in the discrimination task. The conclusion of this study is that in contrast to memory performance which is related to large resting alpha activity low alpha amplitudes are an indicator for good perceptual performance.
