This research is significant because it explored EMF effects on the hypothalamic-pituitary axis, which regulates stress response and metabolism.
Kritikos JN, Schwan HP · 1975
Researchers studied how radiofrequency energy heats brain tissue by examining spheres with the same electrical properties as brain tissue across frequencies from 10 MHz to 1.2 GHz. They discovered that dangerous "hot spots" of concentrated heating occur inside brain-sized spheres, but only within a specific frequency range. The heating was never uniform, creating localized areas of intense energy absorption.

Scientists applied electrical pulses to algae cells (Valonia utricularis) and found their membranes broke down at 0.85 volts within one microsecond. The breakdown was temporary and reversible, with cells repairing themselves in about 10 seconds. This demonstrated that cell membranes have specific electrical thresholds where they fail.
