摘要

摘要λ波是一种生理性的、三角形的、尖锐的瞬态波,当眼睛睁开时发生在枕部。在视觉扫描过程中,Lambda波与眼球跳动一起出现,当眼睛闭上和睡眠时消失。当被试者在视觉上扫描一幅复杂的图片时,它们最容易被激发出来,因此在视觉上探索一个明亮的物体或房间时就会被激发出来。这些波形的表达似乎是继发于大脑中一个共同区域的功能激活,可能位于顶枕区。

Lambda Waves
ABSTRACT. Lambda waves are physiological, triangular shaped, sharp transients occurring over the occipital regions when eyes are open. Lambda waves occur with saccadic eye movements during visual scanning, disappearing when eyes are closed and in sleep. They are best elicited when subjects visually scan a complex picture, therefore seen during visual exploration of a brightly illuminated object or room. The expression of these waveforms seems to be secondary to a functional activation of a common region in the brain, probably localized within parieto-occipital region.
