Equal numbers of responses were obtained from mice tested in the four symmetrical magnetic field alignments. The directional preference of each mouse was tested once in one of four magnetic field alignments by releasing it at the center of the maze with access to all four arms. Between trials, the training arm and magnetic field were rotated by 180 degrees so that the mouse had to swim in the same magnetic direction to reach the submerged platform. In each trial, a mouse was confined to one arm of the maze with the submerged platform at the outer end in a predetermined alignment relative to magnetic north. Naive mice were given two brief training trials. Here we show that C57BL/6 mice can learn the magnetic direction of a submerged platform in a 4-armed (plus) water maze. water maze, radial arm maze) have failed to provide evidence for the use of magnetic cues. However, assays widely used to study rodent spatial cognition (e.g. In rodents, nest building experiments have shown the use of magnetic cues by two families of molerats, Siberian hamsters and C57BL/6 mice. Magnetoreception has been demonstrated in all five vertebrate classes.
