TeleFipho

Fiber photometry is a powerful technique to detect calcium signal from specific neuron in awake animals using calcium indicator protein represented by GCaMP. In freely moving condition, the long optic fiber attached to the head of the animal can interfere with experimental setup, therefore can be a limitation factor of your project.

Our innovative new product, TeleFipho, includes all required components for fiber photometry - optic fiber, filter cube, light source, photo detector - and also wireless transmission circuit, in the very smal 3g body. TeleFipho definitely will not block free behavior of your animals, enabling novel experimental approach using fiber photometry.

TeleFipho receiver can be directly connected to PC via USB for fiber photometry data recording in TeleFipho software. TeleFipho software is good enough for simple raw data / low pass filtered data recording.

Data can be directly read from Matlab / Octave, or can be exported to ASCII format.
For more complicated online analysis and / or parallel recording of other physiological data, you can access photometry data as analog signal via BNC on the front panel of TeleFipho receiver so that you can connect external data recording system (e.g. PowerLab from ADI).
