After the 30-min magnet or sham exposure, mice were placed in an open Plexiglas cage (37 x 47 x 20 cm) with cob bedding in the same room as the magnet and sham– magnet. The locomotor behavior of the mice was video-recored for 2 min and the mice were then returned to their home cages in the animal facility room. Two minutes was chosen because in previous experiments  almost all circling behavior ends within 2 min. Behavior was scored for number of rears (with at least one paw touching cage side) or tight circling (complete turns with a diameter no longer than the body of the mouse) by an individual blind to treatment condition.
