| Summary: | 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. |
