Y-maze video analysis system

The three arms of the Y-Mazes video tracking and analysis system (Y-Mazes) are at an angle of 120 degrees to each other, and they are in a radial shape of three equal parts. A maze model for studying spatial memory in animals. It is widely used in learning and memory, Alzheimer's disease, hippocampal/external hippocampal research, intelligence and aging, new drug development/screening/evaluation, pharmacology, toxicology, preventive medicine, neurobiology, animal psychology and behavioral biology, etc. The fields of scientific research and computer-aided teaching in the discipline are the classic experiments for medical schools to carry out behavioral research, especially learning and memory research.

Description Parameters Resources

1. Hardware parameters:

1. Size of single arm of rat: 500×100×300mm

2. Mouse arm size: 300×60×200mm

3. Working voltage: AC220V

4. Electric grid current limiting adjustment range (optional): 0.0~1.0mA, adjustment step 0.01mA

5. Stimulation sound delay 0-255 seconds (optional)

6. The square wave stimulation frequency on each grid is 0-20000Hz, (optional)

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 by learning and extracts them from complex backgrounds. It has strong anti-interference ability and filtering ability. Even if there are many ripples that interfere with the picture, it can accurately track animals.

Tracking method: The tip of the nose, the center, and the root of the tail track three points and analyze 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;

Strong scalability

The software triggers electrical stimulation, gas stimulation, signal lights, horns, etc. through the input and output ports to achieve delay-free synchronization and expand behavioral experiments to a larger dimension;

8. The software is allowed to be installed on multiple computers, supports online and offline video analysis, and facilitates data indicator statistics;

9. Data indicators:

Active evasion time (latency period), number of active evasion, number of passive evasion, number of errors, etc.
