In neurofeedback-based systems subjects can inhibit or enhance a particular rhythm of brain signal in according to operant conditioning principle and therefore control their EEG changes. Researches have shown that neurofeedback training can decrease symptoms of behavioral level in children with Autism Spectrum Disorder (ASD). In this paper neurofeedback training effects on EEG Gamma band in 9 male children affected with ASD by features such as average, variance and power have been assessed. Subjects were under 40 sessions of neurofeedback training and EEG has been recorded in three stages before neurofeedback training, in 20th and the last neurofeedback training sessions. In addition assessing behavioral level (Symptom Assessment Scale) SAS and (Function Assessment Scale) FAS have been done too, three times, before neurofeedback training and 13 times during the course of training once in every three session and three times after finishing neurofeedback training. Statistical analysis of ANOVA and T-test has shown significant variation (p<0.05) in Gamma band SAS and FAS results in children under training. Result shown the significant difference (p<0.03) in Gamma band and also in SAS and FAS tests.
