Neuroanatomy
of Magnetoreception: The Superior Colliculus Involved in Magnetic Orientation in a Mammal
But as with many things in the colorful history
of magnetoreception research, only time will tell if the results hold up.
«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.

The phenomenon challenges biophysicists to formulate testable hypotheses for mechanisms responsible for
magnetoreception of inconsistencies
of the direction
of the MF direction.
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.
Magnetoreception is a type
of sensory perception when animals use magnetic fields to perceive direction, altitude or location.
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.
