Labyrinth detecting space positioning capability in cognitive function of experimental animals

Abstract

The invention discloses a labyrinth detecting space positioning capability in a cognitive function of experimental animals. The labyrinth comprises a labyrinth body. The labyrinth body is formed through enclosing of two or more closed separation walls from interior to exterior at intervals. A partition area between every two separation walls forms a foraging channel. The separation walls are provided with entrances leading to the next foraging channel. Baffles used for limiting passing are arranged between every two adjacent separation walls. The baffles are fixedly connected between the foraging channels, and an induction food disc is arranged in the center of the labyrinth body. The applicable object range of the experimental animals is wide, the labyrinth is not affected by the physiques, the sizes and other factors of the experimental animals, preciseness of experimental data is guaranteed, and the experimental efficiency is high.

Description

technical field [0001] The invention relates to an experimental device for studying animal memory, in particular to a maze for detecting the spatial orientation ability in the cognitive function of experimental animals. Background technique [0002] Animal cognitive function experiments are one of the indispensable and important means for studying the advanced functions of the human brain and other neurosciences, especially for the study of learning and memory functions. At present, maze experiments are usually used as animal experimental models to observe and record the spatial memory data of animals in the maze. [0003] However, there are still some deficiencies in the maze in the prior art, for example: 1, the commonly used three-arm maze, five-arm maze, eight-arm maze and twelve-arm maze can observe animals in this state under food induction or click stimulation However, most of the multi-arm mazes in the experiment are in the shape of straight arms, and the structure ...

[0003] However, there are still some deficiencies in the maze in the prior art, for example: 1, the commonly used three-arm maze, five-arm maze, eight-arm maze and twelve-arm maze can observe animals in this state under food induction or click stimulation However, the multi-arm mazes in the experiment are mostly in the shape of straight arms, and the structure is too simple, which cannot make an effective contribution to the experiment of spatial positioning ability, which affects the rigor of the experiment.

2. The commonly used water maze is experimented on the waterway. The experimental animals search for the path leading to the exit or station through the spatial reference memory marks on the maze, so as to obtain the data of the experimental animals during the experiment; however, in the actual experiment During the operation, since the experiment was carried out on the waterway, the experiments were performed on subjects with good physique, and the selection of model essays was very limited, which resulted in the lack of scientific rigor of the experimental data
