T maze test


In behavioral science, a T-maze (or the variant Y-maze) is a simple maze used in animal cognition experiments. It is shaped like the letter T (or Y), providing the subject, typically a rodent, with a straightforward choice. T-mazes are used to study how the rodents function with memory and spatial learning through applying various stimuli. Starting in the early 20th century, rodents were used in experiments such as the T-Maze. These concepts of T-mazes are used to assess rodent behavior. The different tasks, such as left-right discrimination and forced alternation, are mainly used with rodents to test reference and working memory.

The T-maze is one of a group of various mazes of differing sizes and many shapes. It is one of the most simple, consisting of just two turns - right or left. The maze is only able to be altered by blocking one of the two paths. The basis behind the T-maze is to place the rat at the base of the maze. By placing a reward at one arm or both arms of the maze, the rat must make the choice of which path to take. The decision made by the rat can be a cause of a natural preference within the rat. A study of alternation can be performed by repeating the experiment multiple times with no reward in either arm of the maze. Another experiment that can be performed is the alternation of rewards each time the experiment is performed, proving the rat will choose the arm that was not visited each time the experiment starts.

Rewards within the rats can be types of food, another rat within a cage, an odor, or a type of shelter. By performing this type of experiment, the rat's preferences can be determined. Examples of this could be a rat's food preferences, its familiarity with specific smells and scents, the attraction of the male and female within the maze, and whether a young rat prefers an adult female or an adult male. These simple experiments can determine the rat's psyche on multiple subjects, and ultimately divulge further into the rat's psychological characteristics. It is also important to consider the rodent's behavior. The use of spatial and non-spatial cues is very influential to research findings on memory, spatial learning and the long-term potential (LTP). These cues include the orientation of the maze, extra-maze cues and room configuration cues. Strategies may be affected by the rodent's ability to find cues in the room, the presence or absence of polarizing cues in the room, and the stability of the maze in the room. When analyzing and interpreting experimental data, researchers have to consider the orientation and configuration of the apparatus and cues in the room.
