- After a three-day familiarization to one side, mice had free-choice access to a novel side of the apparatus. Mean (±SEM, n = 12 per group) activity rate (number of beam interruptions per second), time (%) spent in the novel side, and frequency of crossing to the familiar side, measured via photo-beam interruptions by mice on the testing day.
