The Wireless Way: Fiber Photometry

Fiber photometry is a powerful ultra-fast technique used to measure calcium, neurotransmitters, and other molecules in vivo. To use fiber photometry, genetically encoded calcium indicators (GECIs), dopamine indicators (DLIGHT1), norepinephrine indicators (GRABNE), and other fluorescent sensors are first expressed at the location of interest. An optical fiber is then used to excite the sensor and detect the resulting fluorescence.

This eBook covers various topics including the benefits of wireless fiber photometry, the basics of fiber photometry, and more advanced topics.  Examples included are successful fiber photometry in mazes and other complex environments, the benefits of wireless systems in these complex environments, combining fiber photometry with behavioral measures for anxiety, research capsules and an ultra-fast technique used to measure calcium, neurotransmitters, and other molecules in-vivo.
