In 15 cats, the brainstem auditory evoked potentials were registered in far-field and near-field technique after surgical exposure of the rhomboid fossa. By alterations of the stimulus side and change in position of the registration electrodes on the one hand as well as by tract severance on the other hand, some interesting findings could be obtained never published before. Our investigations indicate that the far-field potentials registered from the scalp are generated axonally and constitute summation potentials of several generators. Accordingly, one should not refer to individual generators with regard to the scalp potentials, but rather to brainstem segments in which the individual potentials are generated.
在15只猫中，在菱形窝手术暴露后，采用远场和近场技术记录脑干听觉诱发电位。通过改变刺激侧和记录电极位置，以及切断神经束，获得了一些以前从未发表过的有趣发现。我们的研究表明，从头皮记录到的远场电位是由轴突产生的，是几个发生器的总和电位。因此，对于头皮电位，不应提及单个发生器，而应提及产生单个电位的脑干节段。
