Genetic manipulation in the mouse olfactory circuit reveals an intrinsic role of the circadian clock in the piriform cortex for daily changes in odor-evoked neural activity
Abstract:In mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus is generally thought to be the master circadian clock orchestrating the internal clock of the entire body. On the other hand, olfactory behavior and odor-evoked activity in the piriform cortex (PC) retain circadian rhythmicity in the absence of the SCN. How the circadian rhythm in the PC is achieved independently of the SCN, however, remains elusive. Here, to define neurons regulating the circadian rhythm of the odor-evoked activity in the PC, w… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
