DB113 automatically records the water maze Introduction: In recent years, China's research on learning, memory and its drugs has received increasing attention. In the fields of psychology, medical and preventive medicine, and toxicology, the above units are engaged in research in this area. One of the problems is the degree of instrument automation. Not high, affecting the scientific nature of the experiment and the accuracy of the results. This is one of the motivations we have developed to automatically record the “water maze”. There are many types of labyrinths. It has been used in learning and memory experiments for decades. It is still widely used today. Although electric fans and food lost are commonly used, there are many problems to be paid attention to during the experiment. Fasting before the experiment, the body weight is reduced to 85% of the original body weight. Otherwise, the animal has no driving force or motivation for feeding; if it is an electric labyrinth test, the experiment box should be cleaned after the end of the training to eliminate the animals. The smell left, otherwise the experiment is prone to false positives. The water maze can be used for anti-fatigue tests in addition to learning and memory tests. This is one of the important reasons for our development of water maze. In the study of domestic learning and memory, the use of water maze is less, and there is no water maze that is automatically recorded. In order to develop this instrument, scientists and workers design electronic circuits by reference to the water labyrinth box of West Germany. It has been improved while experimenting, and it has been finalized and it can be promoted. The automatic recording water maze instrument is a domestic creation, which automatically displays the number of errors in the mouse in the water maze and the time required to reach the end point. When the mouse has an error and swims to the exit, it can automatically alarm. Avoid exposure to sunlight in the dark for more than 8 hours. After repeated trials, the mice were continuously trained for 4 days, and 80% of the animals were able to learn to discriminate and reach the end point within 2 minutes. Intraperitoneal injection or oral administration of decaloid, scopolamine, alcohol and taurine can cause memory impairment, that is, the learning rate is greatly reduced, and the time required to reach the end point is significantly prolonged. Studies have also been conducted on certain nootropics, which have been shown to improve memory impairment caused by taurine. Brain Rehabilitation can improve memory impairment caused by scopolamine. The successful development of the automatic recording of the water maze can improve the scientific work of the research work and improve the work efficiency. Technical Parameters: 1, timing range: 0-99 minutes 2. Timing range: 2, 4, 6, 8, 10 minutes, 10 minutes ± 10 seconds 3. Power supply: 220V volts ± 10% 50 Hz. 4, function: <24 watts 5, the size of the shape: 320 × 120 × 250mm3, 800 × 210 × 490 mm3 6, the use of the environment: normal temperature, to avoid strong light, can work continuously for 8 hours.
