Video analysis system for suspended tail experiment

The hanging tail experimental video analysis system suspends the experimental animal's head downwards by fixing its tail, in which the animal struggles desperately to escape but cannot escape, providing an unavoidable oppressive environment. After a period of experimentation, a series of parameters are recorded during the process of the animal in this environment developing a hopeless immobility state, and the typical "immobility state" exhibited by the animal, It reflects a so-called "behavioral despair state". This Behavioural despair test is similar to depression, and is sensitive to most antidepressants. Its efficacy is significantly related to clinical efficacy, so it is widely used in the primary selection of antidepressants.

8. Camera type: 2.8-12mm automatic 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;

Strong scalability: the software triggers electrical stimulation, gas stimulation, signal lamp, horn, micro injection pump, automatic feeder, infrared sensor, gravity sensor, pressure bar, nose probe, touch screen, diet, drinking water, multi-channel electrophysiology in vivo, photogenetics, Calcium signaling and other equipment through the input and output ports. Implement delay free synchronization and expand behavioral experiments to a larger dimension;

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

9. Data indicators: experimental time, resting time and frequency, struggling time and frequency, climbing time and frequency
