Mismatch negativity in chronic schizophrenia and first-episode schizophrenia.
BACKGROUND Mismatch negativity (MMN) is an event-related brain potential that is sensitive to stimulus deviation from a repetitive pattern. The MMN is thought primarily to reflect the activity of sensory memory, with, at most, moderate influences of higher-level cognitive processes, such as attention. The MMN is reported to be reduced in patients with chronic schizophrenia. However, it is unkno...
متن کامل[Mismatch Negativity (MMN) and schizophrenia: a revision].
The Mismatch Negativity (MMN) is an auditory Event- Related Potential which is generated as an automatic cerebral response to any change in the auditory stimulation that exceeds a limit corresponding to the discrimination threshold. It has been widely and consistently reported that patients with recent and chronic schizophrenia display smaller MMN amplitudes, suggesting that this component may ...
متن کاملGray matter deficits, mismatch negativity, and outcomes in schizophrenia.
Reduced mismatch negativity (MMN) in response to auditory change is a well-established finding in schizophrenia and has been shown to be correlated with impaired daily functioning, rather than with hallmark signs and symptoms of the disorder. In this study, we investigated (1) whether the relationship between reduced MMN and impaired daily functioning is mediated by cortical volume loss in temp...
متن کاملEffect of Aripiprazole on Mismatch Negativity (MMN) in Schizophrenia
BACKGROUND Cognitive deficits are considered core symptoms of the schizophrenia. Cognitive function has been found to be a better predictor of functional outcome than symptom levels. Changed mismatch negativity (MMN) reflects abnormalities of early auditory processing in schizophrenia. Up to now, no studies for the effects of aripiprazole on MMN in schizophrenia have been reported. METHODOLOG...
متن کاملMismatch negativity, social cognition, and functioning in schizophrenia patients.
BACKGROUND Cognition and social cognition have been found to influence functional outcome in schizophrenia patients. However, little is known about the underlying neural substrates that are associated with social cognition or daily functioning. Prior studies found associations between mismatch negativity (MMN), an event-related potential response indexing early auditory processing, and function...
