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

Features

• World first commercial wireless fiber photometry
• Small headstage / good for mice, rats, marmosets, etc.
• Standard 2.5mm ferrule cannula
• Rechargable by a dedicated charger
• Adjustable excitation LED power
• Adjustable signal offset
• For GCaMP or GFP-like indicators

Stand alone / External recorder

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

We recommend the open-source pMAT software for delta F/F and PETH and analysis, developed by Dr. David Barker in Rutgers University. For more details please see the following support page:

Analyze TeleFipho Data in pMAT software

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)
