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.
