EEG Based Cognitive Brain Mapping in Time Domain to Analyze EM Radiation Effect on Human Brain
A progressive rise in the daily usage and dependency over electronic gadgets has been witnessed across the world since a decade. Most of the electronic gadgets involve the direct exposure to extremely harmful levels of highly dangerous electromagnetic radiations (EM). The chronic exposure of these EM radiations may adversely affect the human health. An attempt has been made to investigate the EM radiation effect on human brain using electroencephalography (EEG) analysis. A detailed event related potential and topographic map analysis of acquired EEG signals has been done using MATLAB and studied as an outcome during two states viz., normal relaxed state and EM radiation exposure state. Significant rise in potential concentrations has been observed at frontal and frontal-temporal regions of scalp during radiation exposure state. This has also been inferred from three dimensional topographic scalp maps of human brain. This indicates that the time domain analysis of EEG responses possess the ability to be developed as a tool to assess the level of radiation exposure on cognitive functions of human brain. It could lead to explore and correlate a variety of health effects such as memory loss, cognitive impairment, brain tumors, headaches, frustration, anxiety, etc with the EM radiation exposure.
