Sensory attenuation deficit and auditory hallucinations in schizophrenia: a causal mechanism or a risk factor? Evidence from meta-analyses on N1 ERP-EEG component.

Sensory attenuation (SA), the dampened perception of self-generated sensory information, is typically associated with reduced ERP signals, like for the N1 component of auditory ERPs. SA, together with efficient monitoring of intentions and actions, should facilitate the distinction between self-generated and externally-generated sensory events, optimizing the interaction with the world.According to many, SA is deficient in schizophrenia. The question arises whether altered SA reflects a sufficient mechanism to explain positive symptoms like auditory hallucinations.
