Abstract

EEG is one of the best methods for estimating brain function. Topographic EEG is made by analyzing the power spectrum of EEG as equivalent potential (EP). In this study, the changes in topographic EEG after glycerol administration were observed by statistic calculation of EP in brain tumor patients.
