T Maze and Y Maze

Assessing Working Memory

T-Mazes are widely used to assess working memory in spontaneous, rewarded, or delayed alternation tasks. Each T-Maze consists of two choice arms and one start arm mounted to a start compartment. Both choice arms are equipped with food cups for pellet reward. 3 manual doors are included – automatic doors are available on request. The T-Mazes are available in several sizes and colors depending on the color of the animal under study. A support frame can be combined with the maze for comfortable handling. Special IR translucent mazes allow tracking of animals under each light condition – even in complete darkness – when they are combined with the TSE IR-Boxes.

The T-Maze is operated together with the video tracking system TSE VideoMot2. The movement track of the animal throughout the maze is displayed and region visits are output in real-time. Control regions can be used to stop the experiment after the animal has reached the baited food receptacle (or any food receptacle). The Zone Monitor protocol calculates the number of correct and incorrect arm visits, average speed, latency to reach the food trough and outputs a chronological list of region visits.

The Y-Maze is an easy-to-use working memory test based on spontaneous exploration and alternation between arms – neither training nor food restriction are required. Three identical arms are mounted symmetrically on an equilateral triangular center. Rat or mice Y-Mazes in various colors – also translucent models for combination with TSE IR-Boxes – can be used together with the video tracking system TSE VideoMot2 that offers a dedicated analysis protocol providing results parameters such as the number of alternations calculated from overlapping triplets of arm visits. No need to use a macro to calculate this parameter from the exported zone visit sequence.
