Audiol., Commun. Res. [online]. 2017, vol.22, e1831.  Epub 24-Jul-2017. ISSN 2317-6431.  http://dx.doi.org/10.1590/2317-6431-2016-1831.

Introduction

Mismatch Negativity (MMN) is an electrophysiological potential that evaluates the brain’s capacity to discriminate sounds, regardless of attentional and behavioral capacity. Because it is an objective and user-friendly measure, it becomes promising in the study of auditory processing research in children.

Purpose

To verify the applicability of Mismatch Negativity (MMN) in children.

Research strategy

A search was conducted in August and September 2016 using the descriptors Evoked Potentials, Auditory AND Children, Event-related Potential AND Children and Electrophysiology AND Children in bibliographic collection of the electronic databases Portal BVS (Medline, IBECS and LILACS) and SciELO.

Selection criteria

The selection of articles was carried out in Portuguese, English and Spanish published up to September 2016 without initial date limitation and whose approach to Mismatch Negativity was with the child population.

Results

The search strategy resulted in the selection of 23 articles classified as original articles. The studies evidenced several applications of MMN in children, including autism spectrum disorder, auditory processing disorders, cleft lip and palate, prematurity, and language-specific disorder, being the majority of them in dyslexia.

Conclusion

Despite the great variability involved in the measures of MMN, there is a wide clinical applicability of this electrophysiological potential in the infant population.
