The spatial distribution of the pattern-evoked potentials on the face was studied with a simultaneous 16-channel recording system. The potentials had the first positive component at a peak latency of approximately 55 msec, which was much earlier than the latency of the response picked up from the scalp. The maximal potential value in the maps was found at the region around the stimulated eye. This configuration of the equipotential map was not influenced by defocusing and check size of the pattern, but was altered by changing the contrast. Our results of equipotential maps constructed at around 55 msec after pattern reversal proved that the responses recorded in the facial region originated in the retina and were not a reflection of the scalp potentials.
使用同步16通道记录系统研究了面部模式诱发电位的空间分布。这些电位在约55毫秒的峰值潜伏期出现第一个正波成分，这比从头皮记录到的反应潜伏期要早得多。在图中，最大电位值出现在受刺激眼睛周围的区域。这种等电位图的形态不受图案散焦和尺寸的影响，但会因对比度的改变而变化。我们在图案反转后约55毫秒构建的等电位图结果证明，在面部区域记录到的反应起源于视网膜，并非头皮电位的反映。
