Abstract

This work represents generalization and the analysis of the long-term own materials characterizing reaction of the brain on electromagnetic radiation of low intensity (energy flow density in the continuous regime or in the impulse approximately 500 microW/sm2) and a short exposition (approximately 30 min). A set of the experimental results received on separate neurons, formations and brain as a whole give an idea about the reaction of the central nervous system to the studied influence. Comparison of these data with the corresponding responses to the known incentives (light, sound, electric current) testifies to the electromagnetic radiation of low energy flow density and a short exposition as a sub-threshold irritant for the central nervous system.

Main findings

The paper summarizes and analyzes the authors’ long-term experimental materials on brain reactions to low-intensity electromagnetic radiation (~500 microW/cm2 in continuous or pulsed mode) with short exposure (~30 minutes). The authors report that comparisons with responses to other stimuli (light, sound, electric current) suggest this EM radiation acts as a sub-threshold irritant for the central nervous system.

Outcomes measured

  • Central nervous system/brain responses
  • Neuronal responses

Limitations
