In an object recognition task mice were first allowed to explore a stimulus object. Then mice were removed from the arena, exposed to a magnetic field and replaced in the test arena, which contained a novel object in addition to the original familiar object. The role (familiar vs. novel) and position of the two objects was counterbalanced and randomly assigned.Three different exposure groups (each n=17) and one sham exposure group (n=17) were studied.
cognitive/behavioral endpoints: non-spatial working memory: spontaneous exploratory activity (object recognition task: mean exploration time of the familiar object and the novel object and mean total exploration time)
