[An electric T test topographic map study of the brain in uremia]

This paper reports the results of statistical mapping on cerebral electric power abnormal distributions in 35 cases of uremia, using cerebral electrical T test topographical map method. The results indicated that the abnormal wide distribution of cerebro-electric activity of uremia was significant (P less than 0.01). The power density of slow wave markedly increased in the right parietal region. The power density of alpha wave obviously decreased in the right parietal side. This study clearly showed that the brain lesions have both the generality of diffuse damage and the particularity of focal damage. A region was seriously invaded by the lesion. The brain lesions have metabolic and toxic encephalopathic features.
