Test Description: A large arena (40 cm x 40 cm) with infrared beams at three different levels is used to record rearing, hole poke, and locomotor activity. The animal is placed in the center and its activity is measured. Data from this test is analyzed in 4 or 5-minute intervals. The total distance traveled (cm), vertical movement number (rearing), number of hole pokes, and the center:total distance ratio are then graphed. |  |
