What is fiber photometry?

Fiber photometry is a neuroscientific technique used to measure neural activity in freely behaving animals. It involves implanting an optical fiber into a specific brain region to deliver excitation light and collect fluorescence signals emitted by genetically encoded calcium indicators (GECIs) expressed by neurons. Changes in fluorescence intensity correlate with neuronal activity, providing a measure of population-level neural dynamics. It is commonly used to study neural circuits involved in behavior, learning, and neurological disorders.

What other technologies are related to fiber photometry?

fiber photometry Competitor Technologies

Electrophysiology directly measures the electrical activity of neurons, providing more detailed information about individual neuron firing patterns than fiber photometry, which measures population activity via fluorescence.
