Effects of auditory hallucinations on the mismatch negativity (MMN) in schizophrenia as measured by a modified ‘optimal’ multi-feature paradigm

This is the first study to examine MMN in SZ and to report a significant difference in duration MMN amplitude between patients and healthy within the modified (Optimal-3) multi-feature MMN paradigm. This study corroborates previous research reporting a robust duration MMN deficit in schizophrenia and supports previous findings suggesting that AHs may contribute to MMN deficits in schizophrenia.

Resting-state EEG in schizophrenia: Auditory verbal hallucinations are related to shortening of specific microstates

Microstates of class D resemble topographies associated with error monitoring. Its premature termination may facilitate the misattribution of self-generated inner speech to external sources during hallucinations.

These results suggest that microstate D represents a biological state marker for hallucinatory experiences.
