Abstract

The present research has originated from observing a 25-year-old man who - after an electrotrauma-- showed a hydrocephalus internus in the pneumoencephalogram. The review of the literature available at that time resulted in obtaining only one information concerning this nexus of related problems; thus the search of patients suffering from this trauma began, but as well experiments on animals. Most of the cats being injured by A.C. actually showed a dilatation of the lateral ventricles. Further experiments on dogs have shown that not only in case of transcerebral but also of peripheral injuries by electric currents of certain strength, distinct states of paling on the brain surface could be observed occurring in consequences of the extreme vasosoconstriction of the meningeal vessels. By a further series of experiments on dogs, there was finally demonstrated that also after peripheral electric irritations resp. injuries of different variations, electric tensions in the brain can be measured by intracerebrally installed electrodes at varying irritatnt voltages; up to now, this possibility has been in contest. Neuropathological investigations showed intracerebral and subarachnoid haemorrhages of different size in all injured animals.
