Mismatch 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 کاملAuditory Evoked Potential Mismatch Negativity in Normal-Hearing Adults
Introduction Mismatch Negativity (MMN) corresponds to a response of the central auditory nervous system. Objective The objective of this study is to analyze MMN latencies and amplitudes in normal-hearing adults and compare the results between ears, gender and hand dominance. Methods This is a cross-sectional study. Forty subjects participated, 20 women and 20 men, aged 18 to 29 years and hav...
متن کاملAuditory imagery mismatch negativity elicited in musicians.
A mismatch between auditory sensation and expectant imagery of syllables elicited a possible equivalent of mismatch negativity in a previous study. The purpose of this study was to verify whether auditory imagery from musical notation could also mediate such imagery-based mismatch negativity. Neuromagnetic recording was obtained from eight musicians, who were instructed to identify unpredictabl...
متن کاملSerotonergic modulation of mismatch negativity.
Neurochemical mechanisms mediating the interaction between emotional and cognitive processing are not yet fully understood. Here, we utilized acute tryptophan depletion (ATD) to reduce the brain synthesis of serotonin (5-HT), which is thought to have a central role in regulation of emotions and mood in humans. ATD effects on event-related potentials and magnetic fields were studied using a pass...
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 ...
