Biophysical Mechanism of Animal Magnetoreception & EMF Bioeffects

December 29, 2024
Ref. Panagopoulos, D.J., Karabarbounis, A. & Chrousos, G.P. Biophysical mechanism of animal magnetoreception, orientation and navigation. Sci Rep 14, 30053 (2024) https://www.nature.com/articles/s41598-024-77883-9 Summary The authors describe a biophysical mechanism for animal magnetoreception, orientation and navigation in the geomagnetic field (GMF), based on the ion forced oscillation (IFO) mechanism in animal cell membrane voltage-gated ion channels (VGICs) (IFO-VGIC...

A Putative Mechanism for Magnetoreception by Electromagnetc Induction in the Pigeon Inner Ear

March 4, 2021
Magnetoreception in the inner ear of pigeons (Nimpf et al. 2019) Some animals can sense magnetic fields and use them for orientation. Various mechanisms have been discussed in this regard, yet little is known about whether and if so, where such sensory structures to detect static magnetic fields exist in these animals. The study by...
