The T maze is an enclosed apparatus in the form of a T placed horizontally, similar to the Y maze. Animals usually start from the base (long arm) of the T and allowed to choose one of the goal arms. The test relies on either spontaneous alternation or rewarded alternation(1). See the video for how to grade this maze. Optional food wells, doors, and return to start arms can be added to your order a-la-carte. Non-reflective options are made in the interior of the maze on request.
