Entropy analysis to study the effects of mobile phone radiation on brain

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 variation in feature parameter with respect to parameter at rest is greater in almost all of the channels while using phone-2 (CDMA). Asymmetry index (coefficient of variance) of left and right channels is compared to check the left right symmetry while using phone. The ratio of asymmetry index with phone to asymmetry index at rest lies within the range, so there is no change in symmetry of the brain due to mobile phone radiation.
