Abstract

Phenomenon of augmenting-reducing was studied based on Livanov's concept on the spatial synchronization of biopotentials, multi-channel EEG recordings being used. Augmenting-reducing phenomenon is a certain type of response to any coming information. When single light flashes of increasing intensity were applied to 21 human subjects the phenomenon under study displayed wide spatial distribution. In experiments with rhythmical light stimulation the leading role of the spatially limited bioelectrical processes was shown. About 50% of the subjects retained interhemispheric asymmetry in the course of an experiment.

摘要

基于利瓦诺夫关于生物电位空间同步的概念，利用多通道脑电图记录研究了增减现象。增减现象是对任何传入信息的一种特定类型的反应。当对21名人类受试者施加强度递增的单次闪光时，所研究的现象呈现出广泛的空间分布。在节律性光刺激实验中，显示出空间受限生物电过程的主导作用。约50%的受试者在实验过程中保持半球间不对称。
