“A History of Psychotronic Weaponry” In 1974 the book ELF and VLF Electromagnetic Field Effects edited by Dr. Michael Persinger (1945-2018) was published. This book references and details many studies conducted with animals and humans pertaining to physiological and biochemical changes associated with electromagnetic (EM) fields in the extremely low frequency (ELF) and very low frequency (VLF) ranges. Dr. Persinger writes that ELF signals are preferable because they, “…have the capacity to penetrate structures which house living organisms.” He’s writing about hitting people inside of buildings with psychotronic weapons! https://www.activistpost.com/2024/07/the-abstract-episode-39-a-history-of-psychotronic-weaponry.html
