Structure and function of the vertebrate magnetic sense

Article Abstract:

Research using a discrimination training process shows that the fish Oncorhynchus mykiss exhibits behavioural responses to the Earth's magnetic field. The rainbow trout is just one of several vertebrate species which has magnetic sence. Magnetoreceptor cells, identified on the trout's nose, are indirectly linked to the brain and participate in magnetic sense. Electrophysiological responses are also observed.

Magnetoreception and its trigeminal mediation in the homing pigeon

Article Abstract:

The study demonstrates that homing pigeons can discriminate between the presence and absence of a magnetic anomaly in a conditioned choice experiment. This discrimination is impaired by attachment of a magnet to the cere, local anesthesia of the upper beak area, and bilateral section of the ophthalmic branch of the trigeminal nerve, but not of the olfactory nerve.
