Tested 16–18 mice, randomly selected from three to four different litters, for swim maze performance. The mice received five trials per day on 4 consecutive days. On the fifth day the platform was moved to the center of the northeast quadrant for reversal trials; otherwise the procedure was the same. Latency to locate the platform constituted the total search time of five trials, maximum 150 sec. Trials 1–20 (days 1–4) measured the mouse’s spatial learning ability and trials 21–25 (day 5) its relearning ability.
