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

- EEG based methods of finding NCC neuromarkers have remained productive.
- A review of the main ERP signatures as markers of NCC is provided.
- Pre-, peri-, and post-stimulus epochs of neuromarkers are covered.
- Bioelectric brain potentials negativity as possible NCC is emphasised.
- Problems and controversies in ERP/NCC research are dealt with.

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.
