Evidence from auditory and visual event-related potential (ERP) studies of deviance detection (MMN and vMMN) linking predictive coding theories and perceptual object representations

►A joint review of electric brain potentials of auditory and visual deviance detection is provided. ►Electric brain signals elicited by sensory deviance are suggested to reflect prediction errors. ►Generative models of sensory regularities are proposed to serve as perceptual object representations. ►Sensory deviance detection results are interpreted in terms of predictive coding theories.
