Illuminating Real-Time Brain Dynamics of Neuropeptides with a Fluorescent Biosensor

Neuropeptides play fundamental roles in modulating cellular and circuit functions within the brain. One such signaling molecule – orexin – regulates arousal and wakefulness, and its failure can lead to constant daytime sleepiness (narcolepsy). University of Zurich researchers have now developed a fluorescent orexin biosensor to observe this molecule „live“ in the living mouse brain.
