贝格尔使用灵敏的电流计（埃德曼的大型弦线电流计以及“西门子 - 哈尔斯克线圈电流计”），已经能够记录人脑中产生的电流。他通过在先前做过手术的患者的环钻开口部位硬膜外插入针电极来获取描记图，并且通过将铅箔电极应用于剃光的头皮，从正常人身上也获得了几乎相同的描记图。在曲线中可以看到两种类型的波：“一级”波，约90微伏，最大电压约为0.00015 - 0.0002伏，以及“二级”波，约35微伏。贝格尔回顾了实验性脑电图学的文献，讨论并排除了他自己工作中可能的误差来源，并指出了这种技术方法在神经精神病学中可能具有的未来意义。
Using sensitive galvanometers (the large string galvanometer of Edelmann and the "Spulengalvanometer von Siemens und Halske"), Berger has been able to record the electric currents arising in the human brain. He obtained the tracings by introducing needle electrodes extradurally through the site of trephine openings in previously operated patients, and also nearly identical tracings from normal persons by the use of lead foil electrodes applied to the shaved scalp. Two types of waves are seen in the curves: those of the "first order," of about 90o and a maximum voltage of about 0.00015-0.0002, and those of the "second order" of about 35o. Berger reviews the literature of experimental electro-encephalography, discusses and excludes the probable sources of error in his own work and indicates the possible future significance of this technical approach in neuropsychiatry.
