Abstract

In this issue of Cell Reports Methods, Formozov et al. present an innovative fiber photometry system that uses a fused fiber coupler (FFC) instead of a dichroic mirror to split the excitation and emission light. The FFC-based photometry system is highly flexible and can be easily reconfigured to record from different biosensors.
