Studies in the past have shown that wavelength related VEPs can be recorded from both cortical and noncortical sites. Elements of pattern-specific VEPs for both transient and pattern-reversal stimuli are also obtained from these sites. From the noncortical montage consistent responses are obtained with a major component at about 100 msec, which has been found for both the wavelength related and pattern related VEP. In contrast, the cortical VEP to both types of stimuli include two major components, at around 100 and 200 msec. In pattern reversal these components react quite differently to changes in spatial frequency. The component around 100 msec reacts strongly to a wide range of spatial frequencies when recorded from either cortical or noncortical sites. In contrast, the component around 200 msec, obtained with cortical recording, reacts very strongly to high spatial frequencies and very weakly to low spatial frequencies. This finding corresponds to recent results of single-cell studies in the macaque LGN and striate cortex.
过去的研究表明，可以从皮层和非皮层部位记录与波长相关的视觉诱发电位（VEP）。对于瞬态和模式反转刺激，也能从这些部位获得模式特异性VEP的成分。从非皮层导联可获得一致的反应，其主要成分在约100毫秒，这在与波长相关和与模式相关的VEP中均已发现。相比之下，对这两种类型刺激的皮层VEP包括两个主要成分，分别在约100毫秒和200毫秒。在模式反转时，这些成分对空间频率变化的反应差异很大。当从皮层或非皮层部位记录时，约100毫秒的成分对广泛的空间频率有强烈反应。相比之下，通过皮层记录获得的约200毫秒的成分对高空间频率反应非常强烈，对低空间频率反应非常微弱。这一发现与猕猴外侧膝状体核（LGN）和纹状皮层单细胞研究的最新结果相符。
