Abstract

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 ERP 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.
