The Y-maze test is a behavioral test based on animals' natural exploratory curiosity, in which spontaneous alternating behavior is thought to reflect short-term spatial working memory. It takes advantage of the nature of the tested animals to explore new environments. During the experiment, the tested animals need to remember the previously explored directions every time they switch to explore new directions. Therefore, the Y-maze test can well reflect the spatial working ability of animals.
The Y-maze apparatus consists of 3 arms of equal length, divided into i novel arm, start arm and other arm. The angle between two adjacent arms is 120 degrees, and there is a movable partition in the center of each arm, and different geometric figures are pasted in each arm as a visual mark for the tested animal.
