The Zebrafish 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.
The SCI device is constructed using a steel impounder inserted into a Teflon base. The impounder is attached to the end of the hollow tube by a horizontal pin to guide the weight and to prevent it from bouncing on impact. The weight is made of Teflon coated stainless steel and is supported by a removable pin which is also used to release the weight. Rod magnet is used for retrieval of the weight after the injury.
