Concern about the effect of electromagnetic radiation on human brain increases due to the drastic increase of mobile phone usage. EEG signal is selected to analyze the dynamic changes in brain since EEG reflects the functioning of brain. Due to its non linear characteristics, non linear methods namely wavelet transform is used for analysis. Wavelet Energy of each electrode, relative wavelet energy...
The concern about the adverse effects of mobile phone radiation on the nervous system has increased due to the drastic increase of mobile phone usage. In this paper the mean value of permutation entropy of EEG data set of 21 channels with and without phone is used as feature. ANOVA test is used to compare the features at different conditions. The test is significant only for 5 channels out of 21 channels...
The concern about the adverse effects of mobile phone radiation on the nervous system has increased due to the drastic increase in the number of phone users. The electro encephalo gram (EEG), a record of the oscillations of brain electric potentials reveals the synaptic action that strongly co-relate with brain state. As the EEG signal is non linear, non stationary and noisy, non linear methods will...
The electroencephalogram (EEG) is a record of the oscillations of brain electric potentials. The EEG provides a convenient window on the mind, revealing synaptic action that strongly co-relate with brain state. Fractal dimension, measure of signal complexity can be used to characterize the physiological conditions of the brain. As the EEG signal is non linear, non stationary and noisy, non linear...
