Definition:

The Barnes Maze experiment is a test of learning and memory in mice. In the experiment, mice were placed in a disk with a diameter of 88 cm, and 12 round holes with a diameter of 5 cm were distributed equidistant along the edge of the disk, and an escape box was fixed below the disk. In the learning period (adaptation period), the mice were guided to enter the target hole, and in the research period, whether the mice could enter the target hole within a limited time was detected.
