Our results constitute evidence for the involvement of a specific mammalian brain structure
in magnetoreception.

«The radical - pair mechanism of
magnetoreception is still just a hypothesis, and arguably the best evidence we have for it so far is the effect of time - dependent radiofrequency magnetic fields on the ability of migratory birds to detect the direction of the Earth's magnetic field,» says senior author Peter Hore, an Oxford biophysical chemist specializing
in magnetic influences on chemical reactions.
But as with many things
in the colorful history of
magnetoreception research, only time will tell if the results hold up.

in mammals.

When extrapolated upon other animals and other experiments and observations on animal
magnetoreception, this might explain the non-replicability of many findings and high scatter
in others.
Since the MF is calm
in only about 20 % of the daylight period, our findings might provide an explanation why many
magnetoreception experiments were hardly replicable and why directional values of records
in diverse observations are frequently compromised by scatter.
A 2013 study published by scientific journal Frontiers
in Zoology and conducted by scientists from the Czech University of Life Sciences
in the Czech Republic and the University of Duisburg - Essen
in Germany showed that
magnetoreception might be the reason behind this circling behaviour.
