Abstract:In chronic experiments on cats, using the recording of local blood flow in different regions of the hypothalamus in the sleep-wakefulness cycle, it was found that during paradoxical sleep, the level of local blood flow in the posterior hypothalamus increased significantly, while at the same time in the anterior hypothalamus and in the preoptic region a sharp reduction takes place in local blood flow. In deep slow wave sleep the opposite pattern is observed: the level of local blood flow increases in the anteri… 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.
