Sensory memory during physiological aging indexed by mismatch negativity (MMN).
Physiological aging affects early sensory-perceptual processes. The aim of this experiment was to evaluate changes in auditory sensory memory in physiological aging using the Mismatch Negativity (MMN) paradigm as index. The MMN is a marker recorded through the electroencephalogram and is used to evaluate the integrity of the memory system. We adopted a new, faster paradigm to look for differenc...
متن کاملMismatch negativity
New perspectives in cognitive1,2 and clinical3,4 neuroscience have been opened up with the recent discovery of mismatch negativity (MMN),5 an auditory event-related brain potential (ERP) elicited by infrequent deviant sounds occurring in a sequence of repeated tones.1 The MMN appears as a negative displacement on the ERP to deviant sounds relative to that to standard sounds, with a peak latency...

متن کاملCommentaryI'Naatanen: ERPs and attention Sensory adaptation and mismatch eegatiwitf
Our commentary will dwell only on the interpretation of the elicitation of mismatch negativity (MMN) because the (automatic) detection of physical features of auditory stimuli represents the crucial precondition for all further steps of processing and thus this factor seems of special importance. In the target article, Naatanen proposes (sect. 3.1.1.) two alternative interpretations for the eli...
متن کاملMismatch negativity and late discriminative negativity in sleeping human newborns.
Event-related potentials were recorded from sleeping newborns to compare amplitudes and latencies of mismatch negativity (MMN) and late discriminative negativity (LDN) in active and quiet sleep stages. MMN and LDN were obtained in response to changes in semi-synthesized vowels from 20 healthy newborn infants. MMN and LDN responses were significant for both active and quiet sleep. The amplitude ...
