Abstract

Cell phone emits electromagnetic radiation which could be harmful to human brain after an extensive exposure. The number of cell phone users has drastically increased all over the world. In 2012, the number of cell phone subscribers went up to 6 billion and the majority of them are children and young adults. The main concern is the health risk involved with the cell phone usage. In this paper, the effects of cell phone on human brain are investigated. 16-channels EEG was used to record the brain signal from 24 healthy participants under six different conditions (before experiment, during experiment: right ear with distance, right ear without distance, left ear with distance, left ear without distance and after experiment). After data were preprocessed, the signal irregularity for all the six conditions was computed. Three parameters were used to measure the signal complexity for time series data: i) Composite Permutation Entropy Index (CPEI), ii) Fractal Dimension (FD) and iii) Hjorth complexity. Based on these three parameters, the results showed that the complexity level is high during experiment when the cell phone is at Right ear without distance compared to Left ear without distance for all the brain regions (frontal, central, parietal, temporal and occipital). However, the complexity level decreases with distance when the cell phone is either on right or left ear. The increase in the complexity level explains the presence of high frequency components due to the cell phone radiation. Participants are more exposed to the radiation during the call when the cell phone is without distance. For the frequency domain, absolute power and coherence were used for the analysis. It can be observed from the result that delta, theta and alpha brain waves are lower at both frontal and temporal lobes during cell phone usage. But beta wave is higher during and after call. This is due to the effect of radiation from the cell phone.
