Abstract

Introduction: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects information processing in the nervous sys tem and the procedure of natural brain evolution. the processing and analysis of the brain function of these patients have captivated, Therefore the attention of many researchers. Qualitative Electroencephalography (EEG) is an evaluation method for determining functional brain abnormalities that is different from quantitative EEG. Chaotic tools are used in qualitative EEG whereas linear and nonlinear methods are applied in quantitative EEG. The purpose of the present s tudy is to compare qualitative EEG findings of healthy and autis tic subjects. Materials and Methods: In this s tudy, 19 channels Fp2, Fp1, F7, T3, T5, O1, O2, , of brain signals (Cz, C4, F4, Fz, F3, C3, P3, Pz, P4, T4, F8 At firs t 5-minutes. T6) of 6 healthy and 5 autis tic subjects were evaluated in two phases with closed eyes and then 5-minutes with opened eyes, the subject’ s EEG was recorded. After removing the artifacts, the correlation dimension of the signals was calculated, and . brain maps were plotted to analyze the changes of correlation dimension on the scalp surface Results: By comparison of the brain maps of the healthy and autis tic groups between the opened and closed eyes periods, we found there was a difference between the brain function especially in the T3 and T4 regions of the temporal regions as well as frontal, of the groups Conclusion: Using brain maps, correlation dimension mapping on. and pos terior areas the brain surface provides a better unders tanding of brain dynamics in autis tic subjects.
