[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 کاملMismatch Negativity (MMN) in Freely-Moving Rats with Several Experimental Controls
Mismatch negativity (MMN) is a scalp-recorded electrical potential that occurs in humans in response to an auditory stimulus that defies previously established patterns of regularity. MMN amplitude is reduced in people with schizophrenia. In this study, we aimed to develop a robust and replicable rat model of MMN, as a platform for a more thorough understanding of the neurobiology underlying MM...
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 (MMN) response studies in elderly subjects.
UNLABELLED Mismatch Negativity is an endogenous potential which reflects the processing of differences incurred in the acoustic stimulus. AIM to characterize MMN responses in elderly subjects and compare with adult subjects. MATERIALS AND METHODS prospective study involving 30 subjects, 15 men and 15 women, aged between 60 and 80 years and 11 months. Statistical test: Mann-Whitney. The subj...
متن کاملThe mismatch negativity (MMN) and the McGurk effect
The McGurk illusory percept is obtained by dubbing an incongruent articulatory movement onto an auditory signal. The Mismatch Negativity (MMN) of the auditory Event-Related Potential (ERP) reflects the detection of a deviant stimulus within auditory short-term memory (STM) and besides an acoustic component, possesses, under certain conditions, a phonetic one. The present study assessed the exis...
