Dyslexic is a medical term referred to people suffering from dyslexia. Dyslexia is viewed as a neurological defect that causes the subject's electrophysiological signal of the brain to process information differently from that of normal children. In this paper, we introduce a two-dimension (2D) neural distribution method of analyzing normal and dyslexic children in reading, writing and spelling. The objectives of our experimental study are to extract the unique features, based on comparison between normal, poor dyslexic and capable dyslexic in frequency domain using Spectral Analysis and to study the potential brain area activation using electroencephalogram (EEG) brain imaging method. The 2D result shows that neural activities of normal subject are clearly highlighted on the left hemisphere. In addition, it is found that neural activities of capable dyslexic is higher on the right hemisphere than the left hemisphere, while contrasting result is found with poor dyslexic. © 2014 IEEE.
