1. 1. ERP and MEG Correlates of Visual Consciousness : An Update

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Jona Förster; [2019]
   Keywords : Neural correlates of consciousness; Event-related potentials; Event-related fields; Visual awareness negativity; Late positivity; Global Neuronal Workspace theory; Recurrent Processing theory;

   Abstract : Two decades of event-related potential (ERP) research have established that the most consistent correlates of the onset of visual consciousness are the early visual awareness negativity (VAN), a negative component in the N2 time range over posterior electrode sites, and the late positivity (LP), a positive component in the P3 time range over fronto-parietal electrode sites. A review by Koivisto & Revonsuo (2010) had looked at 39 studies and concluded that the VAN is the earliest and most reliable correlate of visual phenomenal consciousness, whereas the LP probably reflects later processes associated with reflective/access consciousness.

3. 2. Event-related potential correlates of visual consciousness : a review of theories and empirical studies

   University essay from Institutionen för kommunikation och information

   Author : Granit Kastrati; [2012]
   Keywords : Visual consciousness; ERP; Attention; Phenomenal consciousness; Reflective consciousness; The global neuronal workspace theory; The recurrent processing theory.;

   Abstract : Two influential theories of consciousness disagree about if consciousness initially arises along the occipitotemporal cortex to later engage frontoparietal regions and attentional mechanisms, or if it necessarily requires the latter. Consequently, different predictions are made about the temporal emergence of consciousness. READ MORE
