Qeeg Differences In Cordless Vs. Corded Phone Users


Previous research that has measured brainwaves using electroencephalograph (EEC) equipment consistently show that electromagnetic fields (EMF's) of various ranges can alter the neuro-electrical system of the human brain. The results of brainwave research indicate that different levels or ranges of EMF exposure (e.g., 8Hz, 50Hz and 1200MHz) produce different types of corresponding EEG brainwave patterns. The cordless telephone emits an EMF of around 900-1200MHz and no previous research involving cordless telephones or EMF exposure at similar ranges could be found. This study was an empirical investigation of EEG characteristics resulting from 10 minutes of cordless phone (EMF of 900 MHz) exposure. The 10 minutes of exposure to the 900MHz cordless phone resulted in significant magnitude and power changes in the slow wave (Delta2) and the higher (SMR, Alpha, Beta1) frequency bands; However, slow wave theta was unaffected by the EMF exposure of the cordless phone. Overall total EEG power increased and magnitude reflected more instability.
