Mismatch 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...
متن کاملMismatch 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 کاملOscillatory Underpinnings of Mismatch Negativity and Their Relationship with Cognitive Function in Patients with Schizophrenia
BACKGROUND Impairments in mismatch negativity (MMN) generation have been consistently reported in patients with schizophrenia. However, underlying oscillatory activity of MMN deficits in schizophrenia and the relationship with cognitive impairments have not been investigated in detail. Time-frequency power and phase analyses can provide more detailed measures of brain dynamics of MMN deficits i...
متن کاملData on deviance predictability in the assessment of mismatch negativity in patients with schizophrenia
We investigated the MMN at electrode Fz to 12% temporally predictable or unpredictable duration decrement deviant stimuli in 29 healthy controls and 31 schizophrenia patients. With a stimulus onset asynchronicity of 500 ms in the regular predictable condition, a deviant occurred every 4 s while it varied randomly in the unpredictable condition. Here we report detailed data tables and multivaria...
