Abstract

To understand the precise roles of chemical messengers in the brain for communication, we need tools to measure the concentration and release events of neurotransmitters and neuromodulators with great precision. Fluorescent protein–based biosensors with high molecular specificity have been recently developed for direct, optical recording of brain chemistry. Here, we discuss the engineering and applications of the most recently developed genetically encoded neuromodulator sensors for in vivo studies.
