Fiber photometry is an optical technique for measuring chemical signaling in the brain of a freely behaving animal.

After deciding on an experimental paradigm, you will need to cleave your fibers to reach your brain region(s) of interest.

Neurophotometrics makes 4-branch, 200 um core, 1.25 mm ferrule diameter patch cords that are sufficient for most experiments. If you would like a custom patch cord, we provide guidance on specifications and compatibility.

Important considerations to give you a jump-start on the road to learning how to identify good photometry data in real time.

The Neurophotometrics team is proud to announce the publication of our collaborative work with the Proulx lab at CERVO Brain Research Centre of Université Laval. Special thanks to our collaborators, Ekaterina Martianova and Christophe Proulx, for making this work possible!

Cui et al. record in the striatum of freely-moving animals using their newly developed in vivo photometry method.

Meng et al. design a spectrometer-based photometry system that allows for recording in multiple colors.

Pisano et al. utilize tapered fibers to achieve depth-resolved fiber photometry.
