Sharing of the regional division of the animal behavior analysis system

Author：

The experimental results show that the animal behavior system can study and analyze the behavioral trajectories of animals, and realize the synchronization and visualization of physiological data. It is a set of general motion track recording and analysis software, using video camera and computer, using image processing technology to automatically track and record animal activities.

The system is sufficient to identify the active areas of the experimental animals, such as circles, rectangles, etc. set by the experimenter. The collected animal activity images are input into the analysis computer, which can record the position, speed, stay time, movement trajectory, movement distance and other parameters of one or more animals in one or more areas at different times; Design, the software automatically classifies these parameters into the animal activity status report.

The animal behavior system area is generally divided into four corners. Surrounding and central areas, the software automatically calculates the moving distance of the experimental animals in these areas. The dwell time and the number of entries. The average speed; it should be noted here that there are many different divisions of the area. method, many experimenters divide the bottom of the box into the 9th house, 16th house or 25th house.

1. Upright times: It reflects the vertical and horizontal movement state of the rat, and mainly reflects the exploratory behavior. Depressed rats showed reduced curiosity and curiosity about the external environment, so they showed a significant reduction in the number of erections.

2. Overall horizontal movement distance: the response to the rat movement state. For example, the horizontal movement distance of depressed rats will be greatly reduced, and most of them hide in the corners of the open field.

3. Transit time in the central region: the state of anxiety response to mice. Anti-corrosion agents can increase central zone dwell time in mice without affecting general motor status. In addition, the central zone residence time of the depressed rats was also significantly reduced.

4. Total number of transport entries in the central area: Response to anxiety conditions in rats. Anti-corrosion agents can increase the number of accesses to the central area of rats without affecting general motor status. In addition, the number of accesses to the central area of the depressed rats was also significantly reduced.

I hope the above content can help you better understand this system, and you are welcome to continue to pay attention to this site, we will regularly bring you more relevant product knowledge.
