Abstract

In order to find out the topographic structure in alpha wave activity, the principal component analysis method was applied to 17 channel scalp EEGs. Three kind of topographic structures were obtained from the factor loadings of principal components as follows: frontal-occipital, centoral or lateral activity. These structures may be related to the mechanism of alpha activity on the brain.
