Electrical potentials in response to single flashes and to pattern-reversal stimuli presented in Maxwellian view were recorded from several intranasal locations by withdrawing a nasopharyngeal electrode from the epipharynx through the nose in steps of 1 cm. From the anterior parts of the nose a waveform could be obtained resembling the corneal electroretinogram. In the epipharynx an ERG was recorded which was inverted in polarity. This reversal in polarity was explained by assuming an electrical dipole of the retina oriented parallel to the electrode path. When the electrode was below and behind the posterior pole of the eye ball a high-frequency activity of increased amplitude was observed the origin of which could not be explained by the retinal dipole. It is suggested that these increased oscillations originate from the optic nerve. Their behavior is explained by a hypothetical electrical dipole of the optic nerve oriented vertical to the electrode path.
通过将鼻咽电极从咽上缩肌经鼻腔以1厘米的步长撤回，在几个鼻内位置记录了对麦克斯韦视野中呈现的单次闪光和模式反转刺激的电位。从鼻前部可获得类似角膜视网膜电图的波形。在咽上缩肌记录到了极性反转的视网膜电图。这种极性反转是通过假设视网膜的电偶极平行于电极路径来解释的。当电极位于眼球后极下方和后方时，观察到振幅增加的高频活动，其起源无法用视网膜偶极来解释。有人认为这些增加的振荡起源于视神经。它们的行为是通过假设垂直于电极路径的视神经电偶极来解释的。
