The new findings show that the brain has group of neurons which has mirror properties; these neurons called mirror neurons. Despite the fact there is no reliable physiological symptoms associated with Autism , it seems deficit in the mirror neurons in the prefrontal associated with this disorder. The purpose of this survey was finding the evidence on disordered function of the neurons in the children with Autism. This study was conducted through review method. Examined 20 articles published in 2010 _2015, By use the keyword such as brain imaging, mirror neurons, autism, developmental disorder & search in sites such as pubmed, science direct and springer. Primary evidences were supported this neurons role to develop autism symptoms, however recent researches applying brain imaging demonstrated that some factors such as deficit in imitation or theory of mind are related to autism symptoms. Therefore in order to assessment "broken mirror neurons" hypothesis in autism patients and also disappearing the inconsistent evidences, we suggest that researchers note etiology of this disorder with more accuracy in Future investigations and use mixed methods for determining the role of neurons in brain; the methods that in addition to motor tasks assess other tasks too.
