The developmental variation of topographical eeg in childhood


Neurosciences 14(2): 75-77
The developmental variation of topographical eeg in childhood
According to our grouping method of electroencephalogram (EEG), brain waves can be classified to any one group pattern. We have studied on the developmental variation of the EEG in normal and mentally retarded children, and recognized the EEG in mentally retarded children may be as developmentally as in normal. In childhood, the EEG pattern is irregular and asymmetrical, during the aging the slow and high voltage wave becomes more regular and symmetrical. We established the classification of EEG using the classical EEG record-charts and Computed Topographic Display of EEG. We can see the variation emplitude topogram in .delta. wave band, .theta. wave band and .alpha. wave band. From Type B3 to B3 .apprx. AType and to AType, this developmental variation are recognized.
