R821 Tricolor Multichannel Fiber Photometry System

Overview

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

Features

• Three kinds of excitation light sources, that is 410nm、470nm and 560nm, are respectively used for excitation
  of reference, green fluorescence and red fluorescence;
  Support up to 9 channels, suitable for simultaneous experiment of multiple animals or multiple brain
  locations;
• Dual highly sensitive detectors enabling independent and sequential detection to avoid interference of
  fluorescence excitation and detection, acquiring more accurate signal;
  Professional acquisition and analysis softwares are flexible and easy to operate with data processing functions
  available. No matlab programming is required;
• Supports multiple acquisition modes including continuous acquisition, interval acquisition, acquisition upon
  trigger, delayed acquisition and timing acquisition;
• Live display of DeltaF/F acquisition to check scale of signal changes during acquisition;
• Customized adjustment of output signal parameter, easily trigger and control external excitation equipment
  to achieve closed-cycle control of excitation and recording;
• Compatible with optogenetics for recording and stimulation at the same site.
