The amplitude of the potential evoked by a moving grating, recorded from the occipital scalp, is less when it is oblique compared with vertical and horizontal. This inequality is not found by recording the electroretinogram. Thus, orientational effects must arise between the site of origin of the electroretinogram and the evoked cortical response.
从枕部头皮记录到的，由移动光栅诱发的电位幅度，在光栅为倾斜方向时比垂直和水平方向时要小。通过记录视网膜电图未发现这种差异。因此，方向效应必定出现在视网膜电图的起源部位与诱发的皮层反应之间。
