尽管有许多关于视觉刺激的人类平均诱发电位的报道，但这些头皮记录的电位与其潜在来源的关系尚不清楚，尽管刺激相关的视觉诱发电位（VEP）成分通常被认为起源于视觉皮层。猫和猴子等动物视觉皮层中的大多数细胞对轮廓敏感1-3，因此涉及图案或轮廓刺激的研究似乎最有可能提供此类信息。我在此报告一些初步结果，这些结果说明了视网膜刺激的位置对模式相关 VEP 的特征的巨大影响，并表明此类研究如何为这些 VEP 不同成分的来源的可能位置提供线索。
ALTHOUGH there have been many reports about human averaged evoked potentials to visual stimulation, the relation of these scalp-recorded potentials to their underlying sources is obscure, although stimulus-related visual evoked potential (VEP) components are generally thought to originate in the visual cortex. Most cells in the visual cortex of animals such as the cat and monkey are contour-sensitive1–3, and so studies involving patterned or contoured stimulation seem most likely to provide such information. I report here some preliminary results which illustrate the great influence of the location of a retinal stimulus on the characteristics of pattern-related VEPs, and indicate how such studies provide clues to the probable location of the sources of different components of these VEPs.
