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...
