[Specific characteristics of mismatch negativity in infants].

The mismatch negativity component of auditory event-related potentials was studied in fulI-term infants of the first month of life and adults. Acoustic stimuli with large deviance in passive oddball task were used. Research data revealed distinctive features in morphology and specificity in parameters of positive mismatch component in children at early ages. Contrary to results from adult group infant component was manifested in two positive peaks, greater amplitude and longer latency. A significant positive correlation was observed between infant's conceptual age and amplitude, and significant negative correlation was found between gestation age and latency for this positive component. Results allowed proposing specificity in parameters of infant's positive mismatch component indicated proceeding maturational changes in auditory cortex at early ages.
