R811 Dual Color Multichannel Fiber Photometry System
R811 dual color multichannel fiber photometry system is compatible with optoelectronics equipment. It has different wavelengths of excited light, 410nm and 470nm, of which 410 is used to acquire reference signal and eliminate noise. The system can record signal of green fluorescence indicator like GCaMP and dLight or neurotransmitter probe. And also it can be applied to record the neural signal for 9 sites at the same time.
The fiber photometry system records changes in the fluorescence intensity of neurons in a specific brain area to reflect neuronal population activity. In the study of neural circuits, the fiber photometry system can perform long-term stable monitoring of the neurons of freely moving animals, and explore the correlation between neural activity and animal behavior.
Main Applications Ca2+ and neurotransmitter signal detection Study the function of neural circuits Explore the mechanisms of neurological diseases Develop new fluorescent sensor probe Experiment of optical principle
