Abstract: Many animals have ability to percieve the magnetic field of the Earth and use this clue for both orientation and navigation. Yet little is known about physiological mechanism that underlies this sensory ability. Although physiological mechanism still remains unclear, there are three major hypotheses how animals can detect the magnetic field. In this study I focused on the radical pair theory. I analyzed how manipulation of the ambient magnetic field influence the expression of CRY 1, CRY 2 and c-Fos in the pigeon´s retina. I observed in incerased numbers of CRY1, c-Fos and CRY1+c-Fos possitive cells in the ihned nuclear layer (INL) of the retina in animals sbjected to the periodical manipulation of the magnetic field inclination. These data demonstrate that the INL constains a population of neurons that are responsive to magnetic stimuli and strongly suggest that Cry 1 is involved in detection of the Earth magnetic field.
