The instrument is suitable for the forced swimming rats, mice or other laboratory animals, experimental animals were placed through a confined environment (such as water), the animal struggled desperately trying to escape this environment they can not escape, thus providing an unavoidable oppressive environment, some time after the experiment, the animals that showed a typical stationary state, called the behavior reflects a desperate state, recorded in animals that environment produces a desperate state of the process does not move a series of parameters. Products for video and image tracking experiment analysis, the resulting data is automatically output to a PC, you can analyze the experimental process and print test report. It can be widely used in large, secondary Medical School, research institutes experimental teaching and research work of antidepressant drugs. Instrument features: maximum 16 simultaneous experiments in mice, the first side of the image tracking algorithm is efficient and time-saving technology, effectively ensure the authenticity of the results of automated record retention to avoid the interference experiment videos subjective errors introduced by manual counting and animals, the experimenter can Playback checksum provide artificial trajectories, track and coordinate points index results export capabilities
