The influence of electromagnetic fields on human brain activity

Area of Science:

• Neuroscience
• Biophysics
• Electromagnetic Biology

Background:

• Growing use of electromagnetic field (EMF) emitting devices necessitates understanding their biological effects.
• Human brain activity is sensitive to external stimuli, including electromagnetic fields.

Purpose of the Study:

• To investigate the effects of electromagnetic fields from a therapy instrument and a mobile phone on human brain activity.
• To analyze changes in electroencephalogram (EEG) power spectra following exposure.

Main Methods:

• A single-blind, cross-over, placebo-controlled study involving 36 volunteers.
• Exposure to electromagnetic fields from a MediLine "MEGA-WAVE 150/1" device and a mobile phone.
• EEG recordings were taken during and after exposure, alongside a no-field control.

Main Results:

• The MEGA-WAVE instrument exposure led to increased EEG power in Alpha2, Beta1, and Beta2 bands during and post-exposure.
• Mobile phone exposure resulted in a delayed increase (approx. 15 minutes) in the same EEG frequency bands.

Conclusions:

• Both the therapy instrument and mobile phone electromagnetic fields appear to influence human brain activity.
• The findings suggest a need for further research into the neurophysiological effects of common EMF sources.
