This section contains all the necessary components to build a fiber photometry system.
This FPGA based data acquisition unit synchronizes the output control and the acquisition of the input data. This device seamlessly integrates with Doric Neuroscience Studio that provides user interface for multi-channel photometry experiments.
The fiber photometry experiments may require a different number of excitation and detection channels, an optional optogenetically synchronized activation/silencing channel etc., directly affecting the number of the fluorescence cube ports. The sample itself requires fixed or rotating port. As there are number of different possibilities of assigning these ports, our cube classification is based on a number of ports. So far, we offer fluorescence mini-cube models with 3, 4, 5, 6 and 7 ports.
Typically, the excitation optical power in mW range produces fluorescence response in nW range. The detection of such a low level signals requires a low-noise amplified photodetector (APD) or photomultiplier tube (PMT).
