Eight-arm maze experiment video analysis system


The eight-arm maze is a maze model used to study spatial memory in animals. It consists of a central area and eight arms connected around it. Application: It has been used in a series of neurobehavioral-based learning and memory, toxic effects of toxic chemicals and the effects of new drugs or new treatments. The traditional eight-arm maze experiment It is necessary to manually open the doors of each area and feed food manually; this will cause interference when tracking and analyzing with animal behavioral video software and affect the experimental results. The latest eight-arm maze designed by Beijing Zhongshi Technology, the doors of each area can be raised and lowered independently according to the needs of the experiment, and the end of each arm is equipped with an automatic feeding device. (Optional) When the animal reaches the end, the feeding device will throw a food pills. During the whole experiment process, there is no need for the experimenter to manually open and close the door and feed food, which is convenient to operate, reduces interference to experimental animals, and effectively improves the experimental effect.

2. Dimensions: Rat single arm size: length 500mm, width 100mm, height 300mm

Mouse arm size: length 300mm, width 60mm, height 200mm

2. Camera parameters:

1. Camera: gun type

2. Color: color/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 fixed-point drawing method is convenient to draw the labyrinth area required for the experiment. After the experiment, it is found that a certain area is not drawn, and this area can be temporarily added without re-analyzing the video. The software can directly obtain the indicators of this area.

2. Intelligent AI algorithm

The software automatically recognizes the volume and shape of animals through learning and extracts and saves them from complex backgrounds; it has strong anti-interference ability and filtering ability, and can accurately track animals even if there are more ripples that interfere with the picture.

Tracking method: Tracking at the tip of the nose, the center, and the root of the tail and analyzing the data corresponding to the three points at the same time, etc.

3. Diversified experimental process design

The software is openly edited for conditions such as time, area, speed, hardware, steps, events, etc., which is convenient for editing the experimental process mentioned in any literature.


4. Human-computer interaction verification

The software automatically saves the experimental process video, and the experimental video and analysis indicators can be played back simultaneously with the same window, verifying the unity of software analysis and manual calculation, and ensuring the authenticity of the analysis results.

5. Rich statistical indicators

The software can analyze more than 200 indicators such as visit times, stay time, percentage, moving distance, speed, rotation between regions, trajectory diagrams, time series diagrams, heat map, and event relationships of each quadrant or area;

6. GLP management

The software has the function of rights management, the administrator assigns the experimental user account and manages the user rights; reviews the operation of the experimenter

7. Strong compatibility and scalability

Strong compatibility: It can be used as a platform with similar products of other brands at home and abroad. It is convenient to expand and upgrade the platform in the future, and the secondary expansion software will no longer cost;

8. The software is allowed to be installed on multiple computers, the software is allowed to work on laptop computers, supports online and offline video analysis, and facilitates statistics of data indicators;

9. Data indicators:

Working memory error latency, reference memory error latency, total correct times, total arm advance times, working memory error times, reference memory error times, correct latency, correct rate, working memory error rate, reference memory error rate, correct rate before first error .
