The Y-maze is similar to the T-maze, but has three identical arms. Gradual turns of the Y-maze decrease learning time as compared to the sharp turns of the T-maze. The Y-Maze Test is used to test spatial learning and working memory in rodents. This working memory test is based on spontaneous discovery and alternation between arms. In this test no training or food is required. Three identical arms are mounted symmetrically on an equilateral triangular center.
