Shanghai Barnes Maze Test
Shanghai Barnes maze experiment is one of the synthesis of the swantopure, the project experiment is operated by experience
[ 123] Shanghai Barnes Maze Experiment Principles: Animal uses the visual reference substitute, which effectively determines the part of the arm of the craft. The Barnes labyrinth consists of a circular platform, around the platform of the platform, covered with a lot of penetrating platforms. The diameter, thickness, and the width of the platform are different depending on the experimental animals. The number of holes is customized by the experimenter, typically 10 to 30. A box is placed at the bottom of one of the holes, as an evasive place of the experimental animal; the bottom of the other holes is empty, and the test animals cannot enter it. The experimental places are similar to other labyrinth experiments, requiring visual references to experimental animals. The experimental scheme is determined according to the habit of the experiment and the different experimental requirements. After each training, 70% alcohol is cleaned and converted to the correct hole, but the space position of the hole does not change, to prevent animals from finding the hole through the sense of smell . Barnes maze typically uses strong light, noise, and wind blowing such as experimental animals into the motivation of avoiding holes. Observation Index: Determination of the spatial memory capability of animals for the target. When the experiment was placed at the center of the high platform, the experimental animal found the time of the correct hole, and the number of times the income hole was entered with the spatial reference memory capability of the animal. The work memory of the animal can also be measured by recording the number of animals to repeat the number of holes into the wrong hole.
Advantages: No food deprivation and foot shocks are required, so the stress of the animal is smaller. The experiment is small for the physical strength of animals, which can lower the effects of physical strength degradation due to age factors on experimental results. The experiment has less time, and the entire experiment can be completed in 7 to 17 days. It can prevent the animals from completing the experiment with an odor.
