Information-Theoretic Approaches in EEG Correlates of Auditory Perceptual Awareness under Informational Masking

In informational masking paradigms, the successful segregation between target and masker creates auditory perceptual awareness. The dynamics of build-up perception is based on a set interactions bottom–up top–down processes that generate neuronal modifications within brain network activity. These neural changes are studied here using event-related potentials (ERPs), entropy, integrated information, leading to several measures applied electroencephalogram signals. main findings show awareness stimulated functional activation in fronto-temporo-parietal through (i) negative temporal positive centro-parietal ERP components; (ii) an enhanced processing multi-information cortex; (iii) increase content fronto-central cortex. different results provide information-based experimental evidence about during
