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 classical experimental model, it is also widely used for finding an effective tool for the anti-drug-seeking behavior. The experiment will test animals (rats, mice) in the conditioned place preference box of white observation area, and to give psychological dependence drugs (such as morphine), laboratory animals and then observe the condition of the position preference box black area and white between the activities area, the white area, the black area and the gray area where free shuttle wickets for animals. Every animal in the administration area will be under the influence of the drug reward effect on the black and white areas produce Preference position, its degree of psychological dependence and drug related. Features: maximum 8 mice experiments simultaneously, time saving standardization of industrial design, hardware durable, reasonable structure, no smell. Use a video camera tracking technology, automated test process avoids subjective errors introduced by manual counting and interference in experimental animals, the experimental results authentic record retention experiment, the experimenter can playback artificial checksum leading core algorithm, effectively guarantee Identification of noise immunity and accuracy in a variety of display indicators provide trajectory, the trajectory of the coordinate point indicator results export capabilities and can be imported to Excel, user-friendly statistical analysis of new medical type soundproof in Excel, SPSS, SAS, etc. to eliminate the influence of the external environment and laboratory personnel analyze maximize flexibility and support when real analysis and off-line analysis, support timing of the termination and the artificial termination
