自从1953年Evans1首次报道LAMBDA波以来，几项研究，特别是GreenZ和Gastaut和Bert的研究，为LAMBDA机制提供了进一步的信息。然而，目前的研究包含了比以前报道的更详细的λ响应的刺激参数的检查。此外，lambda波的定量主要是通过直接测量进行的，尽管将简要地参考求和技术。特别是，形式，大小，亮度，颜色和运动的视觉刺激所必需的产生λ波已被检查。研究了眼动与λ波的关系以及光响应和λ波响应的相似性。最后，研究了某些心理变量的影响，例如疲劳、心理活动和催眠状态。
SINCE LAMBDA WAVES were first reported by Evans1 in 1953, several studies, particularly those of GreenZ and of Gastaut and Bert,3 have added further information on the lambda mechanism. However, the present study contains a more detailed examination of the stimulus parameters of the lambda response than has been reported previously. In addition, the quantitation of lambda waves is undertaken mainly by direct measurement, although a brief reference to summation techniques will be made. In particular, the form, size, brightness, color, and movement of the visual stimulus necessary for the production of lambda waves has been examined. The relations between eye movement and the lambda wave as well as the similarity of the photic and the lambda responses were studied. Finally, the effects of certain psychologic variables, for example, fatigue, mental activity, and the hypnotic state, have been investigated.
