The EEG signature of sensory evidence accumulation during decision formation closely tracks subjective perceptual experience
Scientific Reports March 20, 2019 Chiara F Tagliabue, D. Veniero, C. Benwell et al.
How neural representations of low-level visual information are accessed by higher-order processes to inform decisions and give rise to conscious experience is a longstanding question. Research on perceptual decision making has revealed a late event-related EEG potential (the Centro-Parietal Positivity, CPP) to be a correlate of the accumulation of sensory evidence. We tested how this evidence...
