The role of mirror neurons in autism impairment

Abstract

Introduction

The discovery of mirror neurons, considered to be responsible for empathy, intrigued researchers all over the world. Many studies have been developed associating mirror neurons to the incidence of Autism Spectrum Disorder (ASD).

Objective

Identifying a possible influence of mirror neuron in autism.

Aims

Reviewing the recent trajectory of neuroscience in relation to the connection of impaired mirror neurons in autism.

Method

Bibliographical review of studies in English, published in SciELO and LILACS databases, between 2008 and 2013. The keywords used were: autism, brain, cortex and mirror neuron.

Results

Different subjects explored the influence of mirror neurons in autism as shown below (Fig. 1). Among 17 studies, 12 were bibliographical reviews and 5 involved experiments. Seventy-six percent of the studies were favorable to the influence of these neurons, while 24% were not.

Conclusion

There was a balance in the distribution of themes explored in the articles and few studies exploring the role of mirror neurons in autism. Even though the current research may not be conclusive, it can be said that currently neuroscientists tend to agree that mirror neurons significantly influence ASD. Recent studies suggest that, if properly stimulated, ASD individuals can develop their social skill and, consequently, be socially inserted. According to most author studied, technological development is needed in order to enable scientific advances involving mirror-neurons and ASD.
