R810 two-color multi-channel optical fiber recording system
Introduction: The optical fiber recording system uses calcium ion fluorescent indicator to record the activity of neurons in specific brain areas. In the study of neural circuits, the fiber-optic recording system can perform long-term stable monitoring of neurons in a group of freely moving animals, and then explore the correlation between neuronal activity and animal behavior. The R810 dual-color multi-channel optical fiber recording system has two excitation light sources of 410nm and 470nm, of which the unique 410nm can be used as a background signal to ensure effective acquisition of real fluorescence data. 9 channels of data can be collected at the same time, suitable for simultaneous recording of multiple brain regions or multiple animals. Features: 1. Using ultra-high sensitivity scientific research-grade CMOS camera, the quantum conversion efficiency is higher, and the acquisition frequency can reach up to 300fps. 2. It can support up to 9 channels of simultaneous acquisition, suitable for simultaneous recording of multiple nerve nuclei. 3. Two kinds of excitation light sources (4 1 0/4 7 0 nm), 4 1 0 nm light source as the reference light source, 470 nm light source excites G C a MP fluorescent protein, which effectively removes motion artifact interference and obtains real fluorescent signal. 4. Integrated digital interface, 4 Input interfaces, support a variety of external signal input and automatic marking, 4 Output interfaces, support outputting TTL signals to trigger external third-party equipment, support 3 signal communication methods: high level, low power Flat and pulse signals meet the needs of closed-loop research. 5. Professional integrated software, fluorescence data and animal behavior video can be collected and analyzed simultaneously. 6. The excitation light output mode can be customized to suit different experimental application scenarios. 7. The software supports the setting of multiple start and end conditions. 8. Support 10 kinds of manual marking and automatic marking, and you can customize shortcut keys, names and colors. 9. Different ROI regions can be set and named during behavioral video collection, and various behavioral analysis can be performed later. 10. The analysis results can be exported to CSV, Heat-map, df/f, Z-Score and other formats. technical parameter: Camera frame rate range: 0~300fps Camera resolution: 2048*2048px Exposure time setting range: 1-100 ms Excitation light wavelength: 410nm, 470nm Received light band: 500 – 550nm LED light power adjustment percentage: 0~100%
