[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 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 کاملCuing the dimension of a distractor: verbal cues of target identity also benefit same-dimension distractor singletons.
Cuing the identity of an upcoming target speeds its detection. This effect is generally assumed to operate on the level of the target dimension, not of its feature identity. Here, we investigated whether that is the case, in a design in which preparing for a cued dimension would incur costs as well as benefits. Participants searched for targets that could be defined on several dimensions, but w...
