“…The results of MMN latencies are in keeping with the findings of auditory cortex maturation found in normal hearing children (17,20), i.e., the MMN latency becomes shorter in association with normal auditory cortex development and 18 maturation (17,20,28). Moreover, such latency decreases from M3 to M6 correlated significantly with the increases in the CAP scores.…”

“…Previous studies have suggested that MMN group average method would improve the signal-to-noise and consequently provide clear MMN responses (17,23,28). Due to the nature of the present study, a combination of both individual MMN analysis and group average method provides a better approach to identify and determine a reliable individual MMN response for analyzing its characteristics.…”

“…The method of group average analysis has been used in previous studies for assessing MMN data in CI users (23,28) as this approach can reduce variability and improve reliability. In the present study, the group average of the different response (i.e., target response minus standard response) was performed using the data obtained from all CI children at the M0, M1, M3, M6 stages respectively.…”

Objective: The aim of this study was to investigate auditory cortical development using mismatch negativity (MMN) in pre-lingual severe to profound hearing-impaired children from switching on the cochlear implantation (CI) and 6 months post-CIs Results: Although the MMN incidence was much lower at the periods of M0 and M1, significantly higher MMN incidence was found in M3 and M6. The MMN latencies decreased significantly from M3 to M6, but no significant difference in the amplitudes was found between these periods. There was a negative correlation between the increment of CAP scores and decrement of MMN latency from M3 to M6.Conclusions: MMN incidence increases and latency decreases are likely to be the objective and noninvasive indicators for evaluating auditory central development at an 4 early stage in children post cochlear implantation. Moreover, the latency decreases from M3 to M6 correlated significantly with the increases of the CAP scores, indicating a fast maturation period, which might be a key period for auditory rehabilitation.

“…En este trabajo se observó que la forma de la respuesta (tanto latencia como amplitud) fue similar en los pacientes implantados y en controles. Además no presentaron diferencias de la amplitud del MMN registrado ipsilateral o contralateral al implante coclear, sugiriendo que la estimulación eléctrica del nervio auditivo activa ambos hemisferios en sujetos con hipoacusia profunda bilateral 53 . También se ha estudiado el MMN en niños con sordera profunda bilateral prelingual con implante coclear (tiempo transcurrido tras el implante fue de por lo menos 45 meses), comparados con niños normales, utilizando tonos de 500 y 2500 Hz, sin encontrar diferencias significativas en la magnitud del MMN 54 .…”

“…Estos trabajos muestran que el MMN en pacientes implantados es similar al que se obtiene en controles normales. Sin embargo, éstos han sido realizados en pacientes implantados con buen desempeño en tareas psico-acústicas [52][53][54] . Sin embargo otros estudios han encontrado que sólo en algunos de los pacientes con implantes cocleares se puede obtener un MMN.…”

El potencial de disparidad o mismatch negativity (MMN) corresponde a la respuesta eléctrica extraída del electroencefalograma que se produce frente a diversos cambios de las características del estímulo acústico. Se obtiene presentando al sujeto una secuencia de estímulos repetitivos de características acústicas similares (estímulo estándar) alternado en forma aleatoria con estímulos acústicos discrepantes que difieren del primero en alguno de sus atributos (estímulo discrepante). El MMN se originaría en la corteza auditiva primaria y se ha logrado registrar desde el nacimiento. No requiere la atención del sujeto, permitiendo evaluar en forma objetiva la discriminación de tonos y fonemas. En clínica se ha utilizado en evaluación del procesamiento auditivo central, pacientes con dislexia o trastorno específico del lenguaje, autismo, individuos con implante coclear e incluso en pacientes en coma. En el presente artículo se revisan las principales características, origen anatómico y utilidad clínica del MMN.Palabras clave: Mismatch negativity, potencial de disparidad, procesamiento auditivo central, corteza auditiva, memoria auditiva, potenciales relacionados a evento. ABSTRACTThe mismatch negativity (MMN) is a specific component of the auditory eventrelated brain potentials. It is elicited by an infrequent, physically deviant sound (deviantstimulus) occurring in a sequence of homogeneous repetitive sounds (standard-stimulus). MMN is probably generated in the primary auditory cortex and it has been successfully recorded in newborns. The MMN can be elicited even in the absence of attention and it can be used as an objective method to assess tone and phoneme discrimination. Some clinical applications of MMN are: evaluation of central auditory processing, patients with dyslexia or language specific disorders, autism, cochlear implant -users and even in prognosis of coma. In this article the main characteristics, origin and clinical applications of the MMN are reviewed.
