| 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).
