ZH-CPP-type CPP conditioned place preference in video analysis system conditioned place preference test (Conditioned Place Preference, CPP) experiment is currently evaluating drug psychological dependence classical experimental model is widely used in the search for an effective tool of anti-drug seeking behavior. The experiment will test animals (rats, mice) in conditioned place preference box white observation area, and give psychological dependence medications (such as morphine), and then observe the animals conditioned place preference box in black areas and white between the activities of the district, the white area, the black area and a gray area where a small door for animal free shuttle. Each time an animal is administered will be in the area of ??action of the drug reward effect generated black and white areas on the position of preference, the degree of psychological dependence associated with the drug. Features: Maximum 8 mice experiments simultaneously, saving time and efficient standardization of industrial design, hardware durable, reasonable structure, no smell. Using a video camera tracking technology, the automation of the experimental process avoids the subjective errors introduced by manual counting and interference in experimental animals, the experimental results true and reliable record retention experiment, the experimenter can playback artificial checksum leading core algorithm, effectively guarantee Recognition of immunity and accuracy in a variety of ways to display indicators provide trajectories, track the results of coordinate points and targets export function can be imported into Excel, user-friendly statistical analysis of new medical type every speaker in Excel, SPSS, SAS, etc. impact of the elimination of the external environment and experimental analysis of personnel maximize the flexibility to support real-time analysis and off-line analysis, the timing of the termination and the artificial termination of support
