※Single maze system
There are two possible maze types available, one with 12 holes and the other with 16 holes. The Barnes circular maze is placed on a frame to set the final height to 90cm above the floor. This height is designed to prevent any effects from the experimenter’s movement on the subject’s behavior. In order to stabilize the subject before testing, the subject is first placed in a start box and then at the start of the experiment, the start box is simultaneously stored underneath the maze during testing. The software includes a navigation function, which provides for a fully automated experiment. The experimenter only needs to place the subject in the start box and place the escape box in the position assigned by the software.
