Welch Power Spectral Density of EEG Signal Generated from Dyslexic Children

摘要

Children with dyslexia or known as specific reading disability, have problem in recognizing some words compare to normal children. In this study, electroencephalogram obtained from dyslexic children during writing words, were analyzed. The EEG signals recorded from 4 channels; C3, C4, P3 and P4 were filtered using a band pass filter with frequency range of 14 to 30 Hz. The signals were analyzed using Welch Power Spectral Density. Analysis of EEG signals showed that dyslexic children use their right hemisphere brain during writing.
