Abstract:
Topographic electroencephalographic study(CME) is a newly developed method using a microcomputer system that displays the scalp topograph as the square roots of the average power spectra over each EEG frequency band on a color television screen. CME were applied to thirty patients, Fifteen patients out of them with focal neurologic deficit were analysed about CT scan and conventional EEG. The results of the study were as follows : 1) Comparing the results of CME and conventional EEG reading, CME revealed to be slightly more sensitive in detecting asymmetrical depression of background activity than the conventional reading of the EEG. 2) Topograph EEG study was more accurate than conventional EEG in lateralization of the lesion. 3) CME is very useful in topographic and objective diagnosis of functional lesion, although the source of the data is the same as that from the conventional EEG.
