The Shepherd's Hook Phenomenon Pattern of Hair Roots: A Demonstration of Comparative Bioelectromagnetism Between Human Hairs and Mouse Whiskers by Means of the Photoelectric Effect

The study explored the biomagnetic fields (BMFs) emitted by human hair and mouse whisker follicles, highlighting cross-species similarities. Using a novel optical microscopy technique, researchers observed that both human hair and rodent whiskers exhibited spontaneous BMFs, expressed as light rays with greater activity on one side. The study employed Prussian Blue Stain mixed with iron particles to detect these fields, revealing that hair shafts and follicles, due to their diamagnetism, repelled diamagnetic crystals and attracted paramagnetic ones. This unique pattern of BMFs was consistently observed and attributed to the photoelectric effect, demonstrating a comparative bioelectromagnetism between the two species.
