Electroretinograms (ERG) and visual evoked responses (VER) were recorded from 2 anesthetized dogs before and after surgical manipulation. The ERG was recorded from a corneal contact lens, and the VET, from 9 different scalp sites. The recordings were made on a signal averager as done in clinical situations. Surgical manipulation consisted of an alcohol block of the stimulated eye and enucleation of the nonstimulated eye. The results indicated that under the conditions of making the recordings, the major and consistent waves of the VER from all scalp sites were a far-field ERG and were not of cortical origin.
在手术操作前后，从2只麻醉的狗身上记录了视网膜电图（ERG）和视觉诱发电位（VER）。ERG通过角膜接触镜记录，VER从9个不同的头皮部位记录。记录是在信号平均器上进行的，就像在临床情况下一样。手术操作包括对受刺激眼进行酒精阻滞和摘除未受刺激眼。结果表明，在记录条件下，来自所有头皮部位的VER的主要且一致的波是远场ERG，并非源于皮层。
