Introduction: Shuttle video analysis system DB079 Shuttle box system is an important means to quantitatively determine animal behavioral changes. It belongs to the classic joint learning conditional reflex, and animals can avoid harmful stimuli through learning. The bottom is a stainless steel grid that uses current plus unconditional stimulation to shock the animal's sole. A noise generator is placed on top to generate conditional stimuli. The condition stimulates an electric shock after a few seconds. If the rat escapes to the safe zone during the ringtone stimulation safety interval, it will take the initiative to avoid the reaction; if the rat does not escape to the safe zone during the safety interval of the conditional stimulus, the passive escape from the escape to the safe zone after the AC shock Positive reaction, otherwise negative for active and passive avoidance, this is a cycle. After repeated training, only the conditional stimulation, the rat fled to the contralateral safety zone to escape the electric shock, which formed a conditioned reflex or active avoidance response, the computer automatic control system can record the relevant animal action parameters. Active avoidance time refers to the length of time that an animal receives a conditional stimulus. The shorter the value, the faster the animal's active avoidance response and the stronger the learning and memory ability. Shuttle video analysis system DB079 This experiment is widely used in the study of memory function, cognitive neuroscience, neurophysiology, neuropharmacology, cognitive degeneration and degeneration of the cognitive function, easy to operate, easy to discriminate results, credibility High, can be used as a test parameter for testing experiments alone, or as an auxiliary or pre-screening experiment for other learning and cognitive function experiments. The shuttle experimental video analysis system is an analysis system through camera video tracking. The system is based on three major components: camera system, computer and stimulator. The experimental animals do not need to be specially marked during the experiment. The software identification algorithm uses trajectory prediction, local and global search technology, and can track and record the position of experimental animals (large mice) arbitrarily. It adopts open system and strong system scalability. The results can be imported into Excel and straightened. The processing of graph\curve\trajectory is convenient for users to further analyze and process in bioanalytical statistical software such as SPSS and SAS. Shuttle Experimental Video Analysis System Software Features 1. Multi-functional, in addition to the shuttle experiment, it is very convenient to make anxiety and learning helpless models. 2.

The software system is powerful and the indicator parameters are rich. 4. Standardized industrial design, hardware is sturdy and durable 5 leading core algorithms to effectively ensure the anti-interference and accuracy of recognition 6. Users can set up separate experimental data archive folders for easy experimental data management. 7. It can record video images at regular intervals, display indicators in various ways, and provide the function of exporting track maps, track coordinate points and index results. 8. The video file format supports AVI compression format, and the compression ratio is high, which can effectively reduce the storage space and facilitate long-term experimental observation. 9. For scientific research and computer-aided instruction (CAI), it can record original video images and provide complete experimental database functions as a real record of research and materials for future teaching demonstrations. Shuttle Experimental Video Analysis System Hardware Features: 1, the hardware system uses embedded microcontroller as the main control core, experimental constant current, constant voltage stimulation 2. The sound delay, voltage and current values are directly set by software. 3. Each electrode has a square wave signal with adjustable peak value. 4. Each electrode adopts a cyclic shift pulsation stimulation method, so that the current that the animal bears is a constant value, and the disadvantage that the animal can not be stimulated by standing on the same electrode is avoided compared with the conventional fixed electrode stimulation. 5. The transmission of all signals in the shuttle video analysis system uses a USB interface. 6. This stimulation system is suitable for animals of different sizes. Technical Parameters: 1. The grid voltage adjustment range: 30~120V (square wave peak), the adjustment step is 1V, and the peak voltage error is less than 5%. 2, the current limit current adjustment range: 0.04 ~ 3.5mA, adjustment step size 0.02mA, current error is less than 0.04mA, can be arbitrarily set according to needs. 3. The square wave stimulation frequency on each grid is 96 Hz with an error of 1%; 4, the stimulus sound delay 0-255 seconds. 5, the input voltage AC220V 6, the main box size: 360 × 300 × 130mm
