ZH-CPP type CPP conditioned place preference video analysis system conditioned place preference test (Conditioned Place Preference, CPP) experiment is currently evaluating drug psychological dependence classic 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 to give psychological dependence drugs (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 areas, black areas and the gray area where free shuttle wickets for animals. Animals in each zone will be administered under the action of the drug Rewarding effects of black and white areas generating preference position, its degree of psychic dependence and drug-related. 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, automated experimental procedure avoids subjective errors introduced by manual counting and interference in experimental animals, real and reliable results video retention experiment, the experimenter can playback leading core labor checksum algorithm, effectively ensuring Recognition of immunity and accuracy in a variety of ways to display indicators provide trajectories, track results and indicators point coordinates export function can be imported into Excel, user-friendly statistical analysis of new medical model every speaker in Excel, SPSS, SAS, etc. impact of the elimination of the external environment and experimental analysis of personnel to maximize flexibility and support for real-time analysis and off-line analysis, the timing of the termination and the artificial termination of support
