CHAPTER FIFTEEN higher animals, such as birds, fish and seals, can orient themselves by using the earth's magnetic pole. When it comes to humans, there is considerable evidence that we are sensitive to changes in electrical and magnetic fields and certain individuals have developed the power to detect minute fluctuations. Some dowsers who have been tested in the laboratory are able to detect electrical currents as these are passed through concealed wires. There is other circumstantial evidence which suggests that the complex electrical circuits of the human brain are influenced by radiation at various frequencies. In the USSR safety standards for non-ionizing radiation are far more stringent than in the West and their laboratories have reported such effects as nausea, headaches, 'buzzings' in the ears and mood changes in connection with low-frequency radiation. It is only within the last few years that any attempt has been made to study these effects in Western laboratories. - The Schumann resonance itself - that frequency at which the whole planet resonates with electrical energy occurs in the same frequency range as human brainwaves. ELFs which are produced in high-pressure areas on clear days have similar frequency to human rhythms. The socalled a-state is associated with a calm and alert brain. Delta rhythms associated with deep sleep fall into exactly the same frequency range as ELFS produced on cloudy, low-pressure days. The hypothesis that our brains are in a state of electrical sympathy with the electrical ocean outside, although not proven, is distinctly persuasive. Tesla's magnifying transmitter, which some people, claimed had been built in Riga, was supposed to operate in a similar frequency range. Could such a transmitter affect the human brain? Some scientists believed that radiation produced before earthquakes could induce mood changes for people in the surrounding countryside. I had read stories of animals and birds which desert an area hours or even days before an earthquake and of people who experienced nightmares of premonition. Now there seemed to be an edge of truth to these anecdotes. Stresses which are released shortly before the main quake would set up shock waves in the surrounding rock. Under compression certain rock formations produce electrical fields which would then travel as ELFs away from the potential quake centre. The possibility that animals and humans living in an earthquake zone 128
