Photometric imaging
Fiber photometry is a calcium imaging technique that captures 'bulk' or population-level calcium (Ca ) activity from specific cell-types within a brain region or functional network in order to study neural circuits Population-level calcium activity can be correlated with behavioral tasks, such as spatial learning, memory recall and goal-directed behaviors. The technique involves the surgical implantation of fiber optics into the brains of living animals. The benefits to researchers are that … WebWhat is Fiber Photometry? Fiber photometry, as a technology, enables the measurement of population-level activity with calcium imaging (Gunaydin et al., 2014).Instead of …
