Recent emphasis upon the importance of the physical environment has
made science and the public even more cog nizant of the many
components of the biosphere. While much attention has been given to
ionizing electromagnetic stimuli which causes blatant and
unalterable changes in biological systems, relatively little
research has been concerned with those electromagnetic signals
whose frequencies overlap with time-varying processes in living
organisms. Extremely low frequency (ELF) electromagnetic fields can
occur as waves between about I Hz to 100 Hz or as short pulses
within this range of very low frequency (VLF) and higher frequency
sources. The natural occurrence of ELF signals is associated with
weather changes, solar disturbances and geophysical ionospheric
perturbations. Man-made sources have also been reported. Certain
physical properties of ELF signals make them excellent candidates
for biologically important stimuli. Unlike many other weather
components, ELF signals have the capacity to penetrate structures
which house living organ isms. ELF wave configurations allow long
distance propaga tional capacities without appreciable attenuation
of inten sity, thus making them antecedent stimuli to approaching
weather changes. Most importantly, ELF signals exhibit the
frequencies and wave forms of bio-electrical events that occur
within the brain and body. Thus resonance inter actions between
animal and nature become attractive possi bilities."
