A preliminary report is given of a study in 10 normal subjects comparing the laterality of the P90 component of the PVEP as elicited by pattern reversal and pattern appearance stimuli delivered monocularly and binocularly in the central and peripheral portions of one-life field. P90 was shown often to appear maximally over the hemisphere ipsilateral to the stimulus field with pattern reversal stimuli in central targets viewed monocularly. Pattern appearance, peripheral targets and binocular stimulation provoked less consistently lateralized and sometimes differently configured responses. It is concluded that while all combinations provoked responses consistent with a dipole generator model similar to that proposed by Blumhardt et al. (1978), these different modes of stimulation cannot be considered to be equivalent.
本文给出了一项针对10名正常受试者的研究初步报告，该研究比较了在单眼和双眼条件下，在一个视野的中央和周边区域通过模式反转和模式呈现刺激所诱发的PVEP的P90成分的偏侧性。结果显示，在单眼观察中央目标时，模式反转刺激下P90通常在与刺激视野同侧的半球上表现最为明显。模式呈现、周边目标和双眼刺激所诱发的反应，其偏侧化程度较不一致，有时配置也不同。结论是，虽然所有刺激组合所诱发的反应都与Blumhardt等人（1978年）提出的偶极子发生器模型一致，但这些不同的刺激模式不能被视为等效的。
