Summary

A patient is presented showing an altered oddball response while suffering from auditory hallucinations. The nontarget stimulus evokes a compound negative potential encompassing a normal early N1 component and an additional negativity within the categorization N2 range. These findings are discussed in reference to impaired mismatch processes and the deranged monitoring of inner speech theory, proposed in schizophrenia.
