Juxtaposing the real-time unfolding of subjective experience and ERP neuromarker dynamics.

Electroencephalographic (EEG) potentials remain a valuable source of data and theories about the neural correlates of consciousness (NCC). This review organizes published work on EEG-based markers of NCC according to the time course of brain potentials relative to stimuli for which awareness is measured or manipulated. Brain potentials are treated as both dependent and independent variables. A notable pattern across studies is that relative negativization of event-related potentials (ERPs) tends to mark NCC.

Abstract

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.
