Video analysis system for elevated cross maze experiment

Rodents (such as rats and mice) exhibit exploratory behavior, and after being placed in an elevated cross maze, they actively explore the open arms, but are afraid of the environment where the open arms hang high and open. Anti anxiety drugs can increase the activity of open arm exploration, while anxiety causing agents can do the opposite. The elevated cross maze is a relatively new method for conducting anxiety research, with reliable results. This product uses video tracking technology to automate and quantify the elevated cross maze experiment, resulting in more realistic, reliable, and objective results.

Description Parameters Resources

1、 Hardware parameters:

1. Elevated cross maze rat size: Arm length: 500 x Arm width: 100 x Arm height: 300mm; Mouse size: Arm length: 300 x Arm width: 60 x Arm height: 150mm

2. Aluminum alloy frame and upgradable bracket for easy replacement of rats and mice

3. By using video camera technology, the experimental process has been automated

4. Container format supports AVI and MPEG-1 compression format

2、 Camera parameters:

1. Camera: Gun type

2. Color: Colorful/Black and White

3. Camera resolution ≥ 640 * 480

4. Camera adapter power supply: DC 12V

5. Camera type: 2.8-12mm zoom

3、 Software parameters:

1. One click drawing area

The labmaze center point drawing method is convenient for drawing the maze area required for experiments. After the experiment, it was found that a certain area was not drawn. You can temporarily add this area without re analyzing the video. The software can directly obtain the indicators of this area.

2. Intelligent AI algorithm

The software learns to autonomously recognize the volume and shape of animals and extract and save them from complex backgrounds. Has strong anti-interference ability and filtering ability, even if there are many ripples interfering with the image, it can accurately track animals.

Tracking method: Track the nose tip, center, and tail root at three points, and analyze the data corresponding to the three points simultaneously

3. Diversified experimental process design

The software is open for editing conditions such as time, region, speed, hardware, steps, events, etc., making it easy to edit any experimental process mentioned in the literature

4. Human machine interaction verification

The software automatically saves the recording of the experimental process, and the experimental recording and analysis indicators can be synchronously played back in the same window to verify the consistency of software analysis and manual calculation, ensuring the authenticity of the analysis results.

5. Rich statistical indicators

The software can analyze over 200 indicators such as visit frequency, stay time, percentage, moving distance, speed, inter regional rotation, trajectory map, time series map, hot zone map, event relationship, etc. in each quadrant or region;

6. GLP management

The software has permission management function, where the administrator assigns experimental user accounts and manages user permissions; Review the operation of the experimenter

7. Strong compatibility and scalability

Strong compatibility: It can be used to build platforms with similar products from other domestic and foreign brands. Convenient for future platform expansion and upgrading, with no additional costs incurred for secondary software expansion;

8. The software can be installed on multiple computers and supports Online and offline video analysis to facilitate data index statistics;

9. Data indicators: open arm and closed arm central area: distance, time, number of entries, incubation period
