T and Y Maze


Our fully automated T-Maze systems for mice and rats can be used to assess working memory in spontaneous, rewarded or delayed alternation tasks and can be modified for acoustic discrimination tasks.

Each T-Maze consists of two choice arms and one start arm mounted at a square center – a start compartment is optional. Both choice arms are equipped with food cups with integrated infrared sensors – software-controlled pellet dispensers are available as an option. Manual doors are included – automatic doors are available on request. The T-Maze software package provides predefined standard paradigms. Choice accuracy is presented in a results table together with time-based parameters such as response latency.

The T-Maze is also available as a non-automated system for use in combination with the video tracking system TSE VideoMot2.


This working memory test is 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 TSE Y-Mazes can be used in combination with the video tracking system TSE VideoMot2 that offers a dedicated analysis protocol.

Fully computerized systems equipped with infrared location sensors at the arm entrances which can be operated regardless of the ambient light level are also available. Data collection and analysis is done with the easy-to-use Y-Maze Windows software.
