Electroencephalographic (EEG) potentials have remained a valuable source of data and theories concerning neural correlates of consciousness (NCC). The EEG based methods are far from being exhausted and are continually valuable in the quest for the markers of NCC. To set the background for the research presented in this issue, we review the published work on EEG-based markers of NCC. The article is organized according to the principle of the time-course aspect of brain potentials with regard to the stimuli for which subject's awareness is experimentally measured and/or manipulated. We treat brain potentials as the principal dependent measure as well as independent variable. More specifically, we also draw attention to the fact that in the overwhelming share of studies relative negativization of the ERPs tends to mark NCC.
脑电图(EEG)电位一直是有关意识神经关联(NCC)的数据和理论的宝贵来源。基于脑电图的方法远未穷尽,并且在寻找NCC标志物的过程中一直具有重要价值。为了为本期刊发表的研究奠定背景,我们回顾了已发表的关于基于脑电图的NCC标志物的研究。本文根据脑电位的时程方面的原则进行组织,该时程与通过实验测量和/或操纵受试者意识的刺激有关。我们将脑电位视为主要的因变量以及自变量。更具体地说,我们还提请注意这样一个事实,即在绝大多数研究中,事件相关电位(ERP)的相对负向化往往标志着NCC。
