Illuminating real-time brain dynamics of neuropeptides with a fluorescent biosensor

Posted: 10 Feb 2022 08:40 AM PST

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). Researchers have now developed a fluorescent orexin biosensor to observe this molecule 'live' in the living mouse brain.
