Labmaze Conditioned Fear Video Analysis System

Labmaze conditioned fear experiment system is a set of video camera and computer, using image processing technology, can automatically control the output of all-digital multi-function stimulator, can choose sound or light as prompt cues, software algorithm automatically determines Mobility, Immobility, Freezing three A system that tracks, records, and analyzes behavioral states and trajectories of multiple animals (which can be flexibly expanded to 16 channels). Labmaze is simple to set up, flexible to operate, and has a high cost performance.

Pre-consultation

Description Parameters Resources

1. Features of the software platform
1. The system can track, record and analyze the behavior status of up to 16 animals at the same time
2. The system can support sound and light signals as clue signals, and according to the experimental specifications, automatically complete the control of various signals such as sound and light required for the experiment
3. The system adopts advanced image processing algorithm to comprehensively process the shape change of the tested animal and other factors, and the obtained factor is used as the judgment condition. At the same time, it also has the function of eliminating electric fence. Its stability and reliability are usually the center of gravity tracking. Algorithms and Interframe Difference Algorithms are unmatched
4. The experimental program of conditioned fear is designed in a visual way, which is displayed in a graphical way, which is simple and intuitive, and can save multiple experimental programs so that they can be selected and reused in subsequent experiments.
5. The system has powerful data analysis and processing methods, which can be analyzed according to the event relationship of the stimulus, or segmented according to time, and the data can be exported to Excel for secondary analysis
6. Support real-time tracking with camera, and offline tracking with pre-recorded video files, resolution up to 640×480
7. While using the camera for real-time tracking, live video recording is possible
8. The original event relationship diagram function enables experimenters to better correlate external stimuli with animal behavior
9. The analysis indicators of the system are rich and varied, not only recording and analyzing Freezing indicators, but also recording and analyzing Immobility and Mobility indicators

Second, the characteristics of the hardware device
1. The all-digital multi-function stimulator is controlled by a microprocessor and outputs sound, light and electrical stimulation signals. There are two output control modes: program and manual.
2. It can output two kinds of electrical stimulation signals, sine wave and bipolar DC pulse, which are compatible with the index standards of Med and Coulbourn.
3.0～4mA constant current electrical stimulation output, adjustable step size 0.01mA, factory precision digital calibration, 9-electrode scrambling (alternate) output, which can effectively avoid short circuit between the "stimulation blind area" and the electric fence of experimental animals, and has a built-in Spliter, which can be used for shuttle Experiment (Shuttle Box)
4.31～16KHz frequency adjustable, volume adjustable sound stimulation output, 65536-level intensity adjustable light stimulation output
5. Standard soundproof box, made of polymer density board, with ventilation and lighting devices
6. The size of the experimental box can be customized according to the specific experiment, the bottom is equipped with a garbage tray, and the design is user-friendly
7. Optical stimulation module can be selected to increase the conditional stimulation mode of the experiment

3. Analysis indicators
Freezing state: Freezing state duration, Freezing state occurrence times, Freezing state latency
Immobility state: Immobility state duration, Immobility state occurrence times, Immobility state latency
Mobility Status: Mobility Status Duration, Mobility Status Occurrence Times, Mobility Status Latency
Others: duration, distance, average speed, trajectory graph, event graph
